If it is a Profibus network, the Profibus address is entered. If it is an MPI network, the MPI address of the PLC is entered here.
be determined as follows:Ĭlick with the right mouse button on the network and select object properties. The subnet ID of the destination network must be specified here. S7 subnet IDĮach subnet in the S7 receives a subnet ID, which is automatically generated by Step 7. Here, settings are made for the destination PLC, the controller from which values are to be read out or written to the values. Slot of the CPU Destination PLC results in the Dest TSAP However, the TSAPs would have to be assembled manually. For the connection path, information of the destination network and the destination station must be known. In S7 it is not necessary to create a connection. For the FETCH / WRITE communication, a connection must only be configured on the OPC side. It does not matter how many gateways it has and how many are between the Ethernet network (where the OPC server station is located) and the destination network. OPC communication is possible with all stations that can be reached via gateways. Routing is the ability of the OPC server to address PLC controllers across subnet boundaries as well.
