Hey,

As far as I am concerned, the s7plc driver works with S7-300/400 PLCs (with built-in Ethernet port or via a CP module). Not sure about the 200 series. Haven't tried it due to its absence.
I presume you should properly setup the connection in Step7 (in Netview if I'm not mistaken). The s7plc driver itself is run on a PC, which initiates the connection.
Either way, I have attached an S7plc-epics manual (using a CP), if that could be of help.

Hello everybody,

I'm new to EPICS and I am planning  to control Siemens Simatic S7-200 PLC. I have looked in EPIC documentation and found at least two ways to connect the PLC:

1. via MODBUS (Asyn) driver over the serial connection (using Siemens MODBUS RTU library)
2. using S7plc driver via TCP/IP and a CP 243-1 Ethernet module.

The programming of the PLC is done using Step-7 Micro/WIN V4.0. Unfortunately I can't open the example STEP 7 PLC project  (for S7plc driver) in Step-7 Micro/WIN.

Do you have any experience with such a configuration or maybe with S7-1200? Are there any better options?

Thanks,
 Konrad
