Experimental Physics and
Industrial Control System

Hi Jens and Saeed,

I asked nearly the same question few months ago on this tech talk. The principal obstacle I found is that I chose "old" material, a CPU 314C 2PN/DP. In the same time, by lack of experience I chose the last version of SIEMENS Software environnement, TIA Portal. With this configuration I failed to use the common solution advised, S7 PLC driver.

The "good vibrations" from  T. JOANNEM (CEA Saclay), D. BRODRICK/N. LEVCHENKO (ESS) , R. LE GEN/E. M. TABAR (Australian Synchrotron) and P. TAYLOR pemitted me to progress in testing many cases. I take advantage of this mail to thank you again for all your precious help.

I finally arrived to establish a communication between EPICS and my PLC by building an IOC using the S7nodave driver. In fact you have not to declare or configure something in TIA Portal, that's why I think it worked with my CPU, and you don't need a 343-1 communication module, because you mentionned that your CPU has the PN port.

But, If you use old material with the old "STEP 7" software, I also recommand you to follow the Yu-Han Lin's PLC configuration document at http://epics.web.psi.ch/software/s7plc/, which would work fine with S7 PLC driver.

With the TIA PORTAL software I recommend to use S7-1200 or S7-1500 PLC at best wich permit a configuration of a new tcp communication required for building an ioc using S7 PLC driver.

Hope this will help you.

Hi Saeed,

all of the 343-1 communication modules should work fine with the s7nodave driver. Actually if you have a S7-300 CPU with DN/DP you don't even need such a communication module because you can communicate in the same way with the Ethernet ports of the CPU directly.

Regards,
Jens

Betreff: Connection to Siemens S7 PLC

Hi all,

I'm new to EPICS and I want to integrate the S7-300 PLC into EPICS. I have read that it can be done by S7 driver via TCP/IP module. But there is some kinds of these modules like 343-1 Lean, 343-1, 343-Advanced. Is there any difference between these kinds of modules in operating with S7 driver? Does CP343-1 Lean work well with s7nodave?

Best regards,
S. Haghtalab
