The ibaLogic project (ibaLogic V5) contains two programs:

• P1_DP_Simulation:

  The data is evaluated by the DP master and the response data to the DP master is generated. The data is exchanged with the P2_DP_Communication program as arrays with 244 bytes. The following tasks are carried out:

  • Definition of the slaves to be simulated

  • Converting the received data (arrays) into the slave-specific data structures (see table above).

  • Processing the received values and generating the data to be sent (simulation)

  • Collecting and converting the data structure to be sent into the 244 byte arrays for data transfer

• P2_DP_Communication:

  The TCP/IP communication with ibaBM-DP is handled here. The user data is sequentially processed, i.e., the headers are added and the data is sent consecutively to ibaBM-DP via TCP/IP. The following functiond are performed:

  • Process control of sending and receiving TCP/IP telegrams.

  • Selection of output data per slave

  • Calling the macro “transmit/receive”

    The macro adds the headers before sending, and evaluates and removes them after the reception.

  • The receive telegram is copied into the slave specific data array.
