Implemented new ESL functions for manipulation with JSON format

D2D-5322 KOM
The functionality of the ""Check Receive Length"" parameter for I/O tags reading binary Modbus registers using functions 1 (Read Coils) and 2 (Read Discrete Inputs) has been corrected.

D2D-2162 EDA
Compiled functions of calculated vectors can be stored in global cache of EDA Server. This, depending on type of calculation, can result in significant speed up of calculations.

D2D-5274 EDA
Logging information about access to EDA vectors has been extended by computer name.

D2D-5275 EDA
Access rights to EDA vectors can now be defined using computer name mask.

D2D-5297 System

D2D-5311 CNF, KOM
A new communication protocol Siemens SIMATIC 3964 (R) CW (Control Web)  has been implemented for serial communication with Siemens Simatic S5 and S7 PLCs. This protocol was implemented to migrate Control Web to D2000 technology.

D2D-5151 KOM
In the OPC UA protocol, the ""Client Type"" parameter has been added which can be set to the ""Secure"" option. This mode supports advanced authentication, encryption, and message signing capabilities.

D2D-5487 CNF, KOM
In IEC 62056-21: 2002 Serial protocol, new parameters have been added that allow more flexible configuration of data reading from profiles:

  • Profile Read Mode (standard/block reading + variants with sending password P1)
  • Profile Read Block Length (block size for block reading)
  • Profile Read Formatted Execution (specification of special command)

The value of a variable defined at the schema level can be defined by an expression.

D2D-5405 KOM
A support for a new protocol - KNX - has been added. See online documentation for more info.

D2D-5788 EDA
Functional vector is new, special type of EDA vectors, that uses vector read parameters (interval and step) as parameters of vector calculation.

D2D-5783 EDA
VBA interface for EDA has been extended with function for calculation of selected statistic over vector values (EDA_StatVector) and with function calculating sum of vector values in group or scenario (EDA_SumGroupOrScenario).

D2D-5272 ARC
The Tell command REOGANIZE has been enhanced so that a tablespace can be specified. Now it is possible to move a table to a specific tablepace on the PostgreSQL platform.

D2D-5283 CNF, KOM
Support for hexadecimal notation of Selector in the address of the I/O tag  was implemented in the LonTalk protocol . The hexadecimal Selector begins with a ""#"", e.g. #1AD.

D2D-5271 KOM
Remia KME protocol has been extended to support reading of generic instant data. These can be of different types (BYTE, SBYTE, WORD, SWORD, DWORD, SDWORD, FLOAT, DFLOAT, RTD). A new protocol parameter ""Generic Actual Data Object ID"" has been implemented to activate the functionality. The address of the I/O tags for generic instant data starts with ""GA"".
The possibility of reading from the event logs has also been added. A new protocol parameter ""Generic Event Object ID"" has been implemented to activate the functionality. The address of the I/O tag that activates reading from the event log is ""RECNR"".

D2D-5287 KOM
In the OPC UA protocol, an option to specify multiple hosts separated by a comma or semicolon in the line configuration has been added, similar to the TCP and UDP line configuration.

D2D-5332 ARC
The calculation of archive objects for the archive with depositories has been optimized. If an archive object has never had a value, when calculating archive objects which depend on it , the archive will not try to read the value from the depositories, even if they are available.

D2D-5391 KOM
Support for writing to array items has been implemented in the OPC UA Client protocol. Only one item can be written at a time; via the output I/O tag with the ""Array Index"" set to a single value.

D2D-5321 HI
AutoCompletteList adapts list width to entryFiled width. A horizontal scroll bar has been added to the list.

D2D-5243 ESL
The ON CHANGE action allow to watch the changes  the local unstructured variable.

The system text length limit has been increased from 20 to 30 characters.

D2D-4706 EDA
EDA-L functions %Replace and %Remove has been improved to support comparison of non-equality against invalid value. Further optimization led up to 15% speed improvement.

Object list can now be sorted using point address.

D2D-5437 CNF, KOM
In the IEC 62056-21: 2002 Serial protocol, a new ""Time Date Mode"" parameter has been implemented that extends the date and time writing capabilities (necessary e.g. for Schrack LZQJ)

D2D-5328 KNL, CNF, KOM
The Honeywell C-Bus protocol, which was only supported on the ""Honeywell C-Bus"" link (a proprietary ISA card was required), was supported on the Serial / SerialOverUDP lines using either a KPX02 communication computer or an RS-485 port computer directly.

D2D-5170 CNF
An ability to copy filtering conditions in dialog for displaying dependencies between objects have been added. Copying can be turned on/off at any time by using the ckechbox.

D2D-5392 KOM
In the Modbus protocol, the ""standard"" version of the 8-byte little endian format   <B8>  was supported using the modifier ""D"" in the address of the I/O tag . Until now, only the format  was supported using the ""d"" modifier.

D2D-5454 HI
Functions %HI_SetBrowserAutoRefresh and %HI_GetBrowserAutoRefresh are also available in the HIX version.

D2D-5514 KOM
In AMiT ATOUCH32 DB-Net protocol, optimized matrix readings (INT_MX, LONG_MX type variables) were also supported for Di, Dout I/O tags.
If there are multiple configured /O tags (not only Di, Dout, but also Ci, Co, Ai, Ao) with the same WID and Type, and if the ""Enable Matrix Read"" parameter is enabled on the station, they will all be read by one optimized matrix reading.
At the same time, the crash of the KOM process during matrix reading (variables of INT_MX/LONG_MX types) into Di, Dout I/O tags and writing Dout I/O tags into matrix was corrected.

D2D-5535 HI
Text mode for RFID readers was supported in the HI process. Mode selection is possible by setting the ""RFID parameters"" parameter string.

D2D-5566 ESL
ESL action LST_CREATE can now create list of all object with possible alarm state.

D2D-5270 System
Support for Kerberos authentication has been implemented in the D2000 Server on the Linux / Raspberry PI platform.

D2D-5614 KOM
A new parameter /KKVOE has been added to the KOM process. It will cause the values of the I/O tags not to be invalidated after a communication error.

D2D-5620 KOM
A newly implemented parameter /KDBC disables the cache for browsing values (Kom Disable Browser Cache) in selected protocols that support spontaneous sending of values without prior request or with group request (IEC101, IEC104, KNX, DNP3). By default, caching is enabled for these protocols, so spontaneously incoming values are stored in it. In configurations with many objects, the cache can take up a significant amount of memory, which this parameter can prevent.

D2D-5619 CNF, KOM
In the IEC870-5-101 (client, server, balanced mode) and IEC870-5-104 (client, server) protocols, the possibility of browsing in the address dialog of the I/O tag and station has been added.

D2D-5643 ARCSynchro
A new parameter /XADC has been added to the arcsynchro utility, which allows you to specify a condition for the ArchivDef table (a table with definitions of archive objects in the archive).
Example of use: when using arcsynchro to copy data from depository segments (e.g. from an Oracle database) to depository segments (e.g. PostgreSQL database) it is possible to specify /XADC ""TRZ_SEG=2"". Only objects that are in depository segment no. 2 will be synchronized. This can speed up data copying (the source depository segment is not queried for object data that is in other depository segments).

D2D-5653 CNF, KOM
A new data type for I/O tags - CHARARR has been implemented in the Siemens SIMATIC S7 ISO on TCP protocol, which allows working with an array of CHARs as if it were a string (STRING).
BCD and LBCD data types have also been implemented, which enable work with 2-byte and 4-byte BCD coded numbers.

D2D-5683 CNF, KOM
In the Siemens SIMATIC S7 ISO on TCP protocol, the possibility of communication with redundant PLCs has been added. Several line parameters for secondary PLC configuration have been added.

D2D-5718 KOM
Support for communication with a device Siemens Microbox (model IPC427C) has been implemented in the ""Siemens SIMATIC S7 ISO on TCP"" protocol. The support is based on ignoring empty answers.

D2D-5801 KOM
Within the callback calling of  GetPoint/GetFastPoint, the value of PointPar.ppPtVal (of KomUniVal type) was set according to the current value of the I/O tag. This can be used for slow protocols using reading in blocks (e.g. Modbus type) to detect if the Transient flag is set. If so, writing to the I/O tag is in progress and setting the value of the I/O tag due to reading should be avoided.

D2D-5825 KNL, CNF
Column filtering allows you to use extended syntax (for example: C [^ o] *).

D2D-5836 CNF, KOM
Support for TCP/IP-TCP line was added to the L&G Toccata protocol

D2D-5866 KOM
Support for DTL format (12-byte date and time with nanosecond accuracy) has been implemented in the ""Siemens SIMATIC S7 ISO on TCP"" protocol.

The S5TIME data type has been added to the ""Siemens SIMATIC S7 ISO on TCP"" protocol. This is a double-byte time - Simatic S5 format (0.001 - 9990 seconds with variable accuracy 0.01 - 10 seconds).

D2D-5915 KOM
A new ""Max Pending Publish Requests"" parameter has been added to the OPC UA protocol, which causes the connection to be closed if the number of unconfirmed consecutive ""Publish request"" messages exceeds this value.

D2D-5943 CNF, KOM
A new parameter ""AcceptReplyToBroadcast"" has been added to the M-Bus protocol. It allows the processing of a specific station's response to broadcast address 254. The default value of the parameter is True (the response to the broadcast is received from any address).

D2D-5991 CNF, KOM
The ""Max Hist Read 1min"" and ""Max Hist Read Others"" parameters have been added to the ESC8816 protocol, allowing you to set the maximum depth for reading historical data (standard 1 hour for 1-minute averages and 30 days for others).

D2D-6011 CNF, KOM
Support for Moire Labs P1AT/P1AP temperature and pressure sensor has been implemented in the LoRaWAN protocol.

D2D-6024 KOM
In the Modbus Client protocol, it is possible to change the ""Addressing Model"" parameter online (without the need to restart the KOM process).

D2D-6019 CNF
Copying of browsing results has been improved in the OPC UA protocol. In addition to copying objects in the current branch of the OPC UA tree (Ctrl+C), copying of all traversed branches of the tree and objects in them (Ctrl+Shift+C) was implemented. The ""Copy tags"" and ""Copy all"" buttons with this functionality have also been added.

D2D-6035 KOM
A new command RELOAD has been implemented in the D2000 KOM process. It is used for internal cancellation and recreation of the configuration of the station and I/O tags, or of the line/stationI/O tags. It is usable after configuration changes that the D2000 KOM process does not have implemented dynamically and that previously required a restart of the D2000 KOM process.
So far the implementation has been tested for IEC-101, IEC-104, ICCP/TASE-2, OPC UA, Modbus Client, and Modbus Server protocols.

**************** Bugs ****************

D2D-5911 CNF
Support for deleting objects in the D2000 CNF via the DELETE key

D2D-5415 DBM
In the DbManager process, several bugs related to reconnecting to a database after a connection breakdown have been fixed. All errors were related to connections opened by SQL_CONNECT using a connect string (as an alternative to a Database object).

D2D-5326 DBM
A crash of DbManager process due to calling SQL_BINDIN without previous SQL_PREPARE was fixed.

D2D-5331 KOM
If a structured control object (default value or output control) was configured for I/O tag, it was not functional after the start of the KOM process. Only the change of its value during the running of the KOM process (or saving of the I/O tag) caused the change of the I/O tag value.
Similar problems could be encountered with evaluating of the I/O tag limits if the limits were configured as structure items.

D2D-5428 DBM
An error was fixed in DbManager that caused it to crash when empty operations for PostgreSQL or an unknown database were turned on. At the same time, empty operations for PostgreSQL database were implemented.

D2D-5430 KNL
The list of alarms was displayed in the D2000 HI before user login.

D2D-5474 KOM
A bug that led to the KOM process crash has been fixed. The crash occurred after changing the value type of the I/O tag (eg Ci -> Ai), which had the destination structure configured, when a new value arrived.

D2D-5285 KOM
The functionality of the inverted polarity output I/O tag (Dout) has been fixed.
At the same time, the behavior of the output I/O tags in the Modbus Server protocol was corrected. The values of the output I/O tags after the correction correspond to the assigned values and not to the values sent to the communication (these are different if the inverse polarity for Dout is activated or the conversion to technical units for Ao, Co is configured).

D2D-5477 HI
Fixed HI crash when Windows time format setting uses more than 12 characters.

D2D-5503 KOM
The following error that occurred on Serial and Moxa IP Serial lines when setting Handhaking = Custom was fixed:
If DTR/DSR handshaking was selected, the DTR setting was dependent not only on the Invert setting but also on whether DTR=0 or DTR=1 (while these settings were disabled in the CNF).
If RTS/CTS handshaking was selected, the RTS setting depended not only on the Invert setting but also on whether RTS=0 or RTS=1 (while these settings were disabled in the CNF).
After correction, the appropriate setting is 1 (ON) or 0 (OFF) if the Invert option is checked.
In practice, these settings were used for older types of converters (eg RS232 / RS485), where the access to the bus was controlled by DTR or RTS signal.

D2D-5571 KOM
An error has been fixed in the IEC 62056-21:2002 Serial protocol, which caused the loss of values at the time of the transition from winter time to summer time (e.g 29.3.2020 at 2:00 am).
The error occurred if the electrometer also sent a winter/summer time flag (characters '0' or '1' at the beginning of the date).

D2D-5592 KOM
The behavior of the I/O tag with an active default value when switching redundancy has been fixed. The incorrect sending of the last telemetric value was fixed - while in the case of an I/O tag with a default value, it was necessary to send the current value, not the telemetric value.

D2D-5608 HI
Calling the% HI_GetPictureWindowState () function crashed the D2000 HI process.

D2D-5627 KOM
A buffer overflow bug was fixed in the Johnson Controls N2-Bus protocol . This error could lead to a KOM process crash if data longer than 1kB was received.

D2D-5644 ARC
The malfunction of the calculated archive object has been fixed. The malfunction (archive object stopped being calculated) occurred with the following sequence:

  • an XML import of the archive object was performed (without changing the configuration, i.e. maintaining the modification time)
  • the archive object was subsequently edited or an XML import was performed with a configuration change.

Such an archive object stopped being calculated until the archive was restarted.

D2D-5647 DBM
A startup parameter /NMI has been added to the DbManager process. This parameter causes a text NULL value read from the database to be interpreted as Invalid. The default behavior (Oracle compatible) is that a NULL value is interpreted as a valid string with a zero length.

D2D-5655 KOM
A  bug in the BACnet protocol was fixed. This bug could cause reading of values on a particular BACnet station to stop working.
The error manifested itself on UDP lines in a configuration with a larger number of stations and a higher communication load.

D2D-5656 HI
In the expression of EXPRESSION variable type no function could be used.

D2D-5679 KOM
A bug was fixed in the IEC-104 Server protocol on the Linux platform, which manifested itself in the fact that after switching KOM redundancy, the process still received one client (despite the fact that it was no longer supposed to listen on the defined TCP port).

D2D-5685 KOM
An error in the OPC protocol was fixed, which could lead to a crash of the KOM process at the start of browsing (depending on the specific OPC server).

D2D-5723 KNL, CNF, KOM
A new parameter ""Immediate Disconnect"" has been added to the Modbus Client protocol (TCP variant). It permits immediate closure of the TCP connection after reading the station, or after writing. The parameter makes sense on unreliable GPRS lines.

D2D-5728 ARC
The following error in the archive has been fixed: if the source for the statistical archive is another statistical or calculated archive with storing of the interval start time, then the calculation was not corrected after calculating the source data for a specific interval. During the first calculation, not all data may have been available yet, after the calculation of the source data, the correction recalculation did not take place. The workaround was to manually trigger the correction calculation with the RECALC tell command. The error only concerned continuously calculated archives.

D2D-5745 ARC
An error in the calculation of on-change calculated archives was fixed in the D2000 Archive. This error could have caused the value not to be calculated. The error occurred if one of the source archived objects was a self-referencing calculated archive.

The crash occurred when the dialog for comparing differences was displayed and by moving the mouse cursor from the object type display area to the object list display area.

D2D-5784 ARC
An error in the archive that affected periodic script-filled archives has been fixed. Their local cache was filled when inserting into archives and was never deleted.
If an isochronous cache was configured in the archive, its depth was gradually reduced and subsequently the memory consumed by the archive increased.

D2D-5786 KOM
A bug was fixed in the KOM process that caused it to crash if the I/O tags were deleted, while all stations with a specific protocol on the parent line were turned off from the start of the KOM process.
The error applies to protocols:
OPC UA Client
OPC XML Data Access 1.01 Client

D2D-5790 KOM
The StOff station status is treated correctly now in several protocols. The current treatment may have caused the communication not to start after the transition from the StOff state:
Generic User Protocol
Honeywell PCNM

D2D-5794 ARC
In the D2000 Archive process, the TrezorReadSinceCreate parameter has been added, which allows you to restrict reading from depositoriess to those depositories that are not older than ""Create Time"" - the time of creation of the respective archive object.

D2D-5815 KOM
A bug was fixed in the KOM process that could cause the occurrence of values with ValType=NaN (but gValType is correct, e.g. Bo) if the I/O tags were configured with process alarms.

D2D-5731 KOM
In the D2000 KOM process, the memory leak that occurred when using text I/O tags in OEM protocols was fixed. A memory leak was inside the callback function PointNewValue.

D2D-5708 KOM
The KomAPI function WriteToLine caused the KOM process to crash if it was called with the parameter Len=0. Sending zero-length data on a TCP line should cause the TCP connection to close.

D2D-5795 KOM
A bug in the Modbus Server protocol was fixed. It could cause clients that connected to the Modbus Server to read incorrect register values after restarting the KOM process.

D2D-5756 KOM
A bug in Modbus Client / Server protocols was fixed. It caused an I/O tag to be ""forgotten"" after editing (or XML import) of another I/O tag that had the same address, differing only in the Modbus function number - e.g. I/O tag with address I3.0 caused malfunctioning of an I/O tag with address I4.0 (register on address 0 in the address spaces Holding register (3) and Input Registers(4)).
In the Modbus Server protocol, the ""forgotten"" I/O tag became Invalid when a new value was written to it.
Workaround: a restart of the KOM process after an I/O tag was edited.

D2D-5676 KOM
A crash of the KOM process in IEC-101 and IEC-104 protocols (client / server), which could occur on redundant lines, was fixed. The bug was present in binaries from 15.6.2020 and later and it was a consequence of the modification of D2D-5619 (implementation of browsing support).

D2D-5821 KOM
Several errors have been fixed in the KOM process that could cause the KOM process to crash in different states (eg when switching redundancy) if stations with different communication protocols were configured on the line.
The error concerned protocols:
Fisher-Rosemount RS3 SCI
Honeywell Excel C-Bus
OPC Data Access 2.05 & 3.0
OPC Historical Data Access 1.20
OPC XML Data Access 1.01

D2D-5826 KOM
A new ""Read Mode"" parameter has been added to the OPC UA protocol. It allows values to be read by polling (ReadRequest) instead of sending notifications by the OPC UA server. This method of reading values has a higher overhead and is only recommended in case of problems with the standard method of reading.

If the calculated archive used the %Arc_GetValue function over the periodic/statistics archive that was calculated on-read and the time used in the %Arc_GetValue function did not match the times for which the source archive was to be calculated, then the %Arc_GetValue function could return bad results.
The fix handles the time specified in the %Arc_GetValue function and adjusts it to the periodicity of the source statistical/calculated archive.
Possible workaround: alignment of time used for the %Arc_GetValue function to a required period.

D2D-5847 ARC
An error in the archive that caused an interval recalculation malfunction (e.g., for the RECALC tell command) was fixed for a calculated archive that did not use other archives in the expression (i.e., a constant computation or a value derived from @EvalTime).
Possible workaround: artificial addition of source archive (e.g. change of expression ""Hour(@EvalTime)"" to ""Hour(@EvalTime) + H.Day - H.Day"").

D2D-5831 HI, KNL
A bug was fixed in temporarily blocking system alarms. The alarm configuration with the Block parameter enabled was incorrectly saved during temporary blocking. After automatic unblocking (after the time limit has elapsed), this parameter remained set. As a result, the alarm could not be blocked again (it was necessary to edit the configuration of the Alarm object and unblock it).

D2D-5887 CNF
A bug was fixed in CNF that made it impossible to enter a negative UTC offset (in objects of type Database, Historical value, Eval tag and Station).

D2D-5889 DBM
A bug that caused the DB (S) _UPDATE_BLOB action to malfunction on Linux/Raspberry PI platforms was fixed.

D2D-5917 KOM
Communication path flags have been added to the OPC UA Data Access Client protocol. If several IP addresses are configured on the line (communication via several redundant networks, or communication to a redundant OPC UA server), then the FLB flag on the station indicates that an alternative IP address (i.e. the second or next one entered) is used. The FLN, FLO, FLP flags indicate which of the alternative IP addresses is used (if more than 2 IP addresses are configured on the line).

D2D-5927 CNF, EVH
The new value assigned to the index local variable did not appear in the ESL debugger.

In multiple protocols, the behavior of changing the address of the I/O tag, which could lead to errors, was corrected. The workaround was a restart of the KOM process. List of affected protocols:

D2D-5814 ESL
Performing a GETARCHSTRUCT, GETARCHROW, or GETARCHCOL action did not free memory. Its size is directly proportional to the number of archive objects that are read.

D2D-5980 ESL
If parameter substr was empty, function returned invalid value

D2D-5997 KOM
In the BACnet protocol, the behavior for I/O tags with their own Read/Subscribe period in the event of a communication failure has been fixed. The fix is to prevent the generation of read requests when such requests have already been generated. The fix prevents the queue from being overflowed with requests to read such I/O tags.

D2D-6018 ARC
A bug was fixed in the implementation of the INSERTARCHARR action. If this action was called with an empty structured variable, requests to recalculate dependent archive objects were generated unnecessarily.

D2D-6033 KOM
An encoding error in the GetVariableAccessAttributes-Response message has been corrected in the ICCP/TASE-2 protocol. The error resulted in a malfunction of the I/O tag with the ""Autodetect"" data type when processing a value with the ""Real"",  ""DiscreteExtended"", or ""RealExtended"" data types.

D2D-6045 WBK
D2000_WorkBook did not accept the Windows language setting. Always use Slovak.
