How do you set up a Fetch/Write connection (S5-compatible communication) to the SIMATIC S5 via Ethernet for the SIMATIC NET OPC server with the SIMATIC NET CD 07/2001 or higher?
In this example, a standard Ethernet network card is used for the S5-compatible communication with the S5 station using the FETCH and WRITE services via the OPC server.
The procedure described here also applies for communication processors CP1613, CP1512 and CP1612.
You can choose between two different configuration tools:
- NCM PC:
NCM PC is supplied with the SIMATIC NET CD and permits you to create PC projects and open STEP 7 projects. However, it is not possible to use this software to edit the S7 blocks in the STEP 7 project.
- STEP 7:
STEP 7 is a separate software package and permits you to create S7-400, S7-300 and PC projects. It is possible to use this software to edit the S7 blocks.
Only one of these tools can be installed.
Please follow the instructions below for configuring the PC station.
