Summary:

This article describes how to set up simultaneous communication with Applicom and Profibus.
Details:

Certain configuration rules must be observed when PCs communicate simultaneously with PCI1500Pfb Applicom cards to a single PLC (type S135) on Profibus network with S5 or S7 messaging.

Solution

The rules are as follows:

  • For the PLC: the coupler must have a different communication ‘contract’ for each PC.
  • For PCs in the Applicom configuration :
    • Each PC must have a personal station number (TS) for the same channel. N.B.: the total station number on the network (HSA) includes the PCs and PLC.
    • Each PC must have a different ‘contract’ number (corresponding to the one declared in PLC’s coupler) for one device. This number corresponds to the LSAP and DSAP fields.

Example

This illustration shows the configuration of the Applicom cards (in the CONFAPLI.LST file) for both PCs:
