Architecture

The individual functionalities of the IPESOFT D2000® system are divided into function-oriented processes in two main categories:

IPESOFT D2000® Application Server Processes

User Interaction Processes

IPESOFT D2000® Kernel

  • IPESOFT D2000® central process – the configuration, data and coordination base of the IPESOFT D2000® system
  • System object management – creating and updating the states and values, maintaining linkage between objects in DODM
  • Asynchronous distribution of real-time values to individual IPESOFT D2000® processes
  • Monitoring of the system operations and significant system inputs by operators
  • System configuration database management
  • System monitoring database management
  • Launching and stopping the IPESOFT D2000® processes, controlling the system software component features (WatchDog)

  • Parallel processes load management (load-balancing)
  • Data synchronization with a standby server, HOT/STDBY Failover arbiter
  • User access management via role hierarchies

IPESOFT D2000® Kom

  • 3-level communication architecture: I/O tag, station, link
  • Openness for devices on the management process level
  • Over 80 communication protocols (IEC 60870-5-101/104, OPC client/server, OPC UA, MODBUS, PROFIBUS, TASE.2, Simatic S7, BACnet etc.) implemented
  • Supports unlimited number of parallel protocols and connected systems, enables communication via multiple serial port
  • Open communication interface allows simple supplementation of communication protocols by the implementation of DLL/C, C++ library over the IPESOFT D2000® KOM-API interface
  • Conversion, filtering, deadbanding and defining replacement values allow effective input data pre-processing with an option to define replacement values in case of a communication outage
  • Change of communication object configuration online during the operations
  • Support for protocols with time marks, time synchronization
  • Support for the data backward uploading method after an outage and communication recovery
  • Support for redundant communication on the communication link as well as RTU station levels

IPESOFT D2000® Alarm

  • Alarm logic with 5 statuses (Normal, Alarm, Acknowledged/Confirmed, Unacknowledged/Unconfirmed, Blocked)
  • Alarm archiving, structured overview of individual alarms
  • Critical and non-critical alarms, alarm priorities, categories
  • Actions launched by the alarm state changes
  • Alarm access controlled by user rights
  • Alarm presentations and notifications in various forms: acoustically and visually on the operator's console, via sending SMS or email

IPESOFT D2000® Calc

  • Real-time processing of mathematical expressions and equations (automatic calculation for the input value change, periodic calculations)
  • Support for the large number of mathematical and objective functions, expressions and conversions, etc.
  • Cascading calculations
  • Bulk calculations over structured data

IPESOFT D2000® Archive

  • Usage of relational SQL databases PostgreSQL, Oracle, Sybase SQL Anywhere, MsSql etc.
  • The basic object is called an archive object. It is used to archive values of any object (I/O tag, calculated point, alarm, etc.).
  • Separately defined storage parameters and archiving depth for each archive object
  • Accessibility of archive object values for all users
  • IPESOFT D2000® Archive supports 4 types of archive objects:

Primary archive – on-change archiving of values, periodic archiving of values with arbitrary time periods
Statistical archive – periodical application of statistical and balancing functions over the data in a source archive (weighted average, integral, etc.). Any type of archive object can be a source archive.
Computed archive - on-change or periodic archiving of values calculated from source archives using mathematical expressions with the same syntax as used by D2000® Calc
Script-filled archive - archive filled only by script from D2000® Event process

  • The depository – time-unlimited archiving in SQL databases, long-term archiving of values on an external backup media or on NAS/SAN. The depositories are implemented as separate databases (PostgreSQL, Sybase SQL Anywhere) or as tablespaces (Oracle)
  • Support for the analysis and data processing by external MS Excel tools (using the IPESOFT D2000® XLS Workbook plugin)
  • Support for processing of delayed data in the IPESOFT D2000® Archive by means of backward calculating of all dependent values in statistical and computed archive objects
  • Automatic mutual synchronization of redundant archive values
  • Bulk archiving of structured data
  • Support for the load distribution between the archives working simultaneously (load-balancing)
  • Internal parallelization of archive's work using several tasks (multi-read and multi-write archives)
  • Implementation of advanced cache intended to minimize database-load and increase read performance (isochronous archive cache)

IPESOFT D2000® Event

  • Custom real-time scripting language ESL (remote procedure calls, standard expressions)
  • JAVA support and its integration with JVM
  • Script launching at a particular event or periodically (seconds to days)
  • Parallel event processing
  • Optional script tuning by users in full system operation (debugger)
  • Integrated libraries used for XML files, libraries for the file operations, etc.
  • Integrated libraries used for relational databases (ODBC, OCI)
