Can the  MODBUS driver be used with TCP on that family of PLCs?

Subject: Connection to Siemens S7 PLC

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
