Re: Siemens S7-300 PLC and EPICS

Hi Florian, 

We had approximately the same project, controling pumps and gauges with EPICS via a S7-300. 

My feedback. The best solution depends on which software you use to program your PLC, STEP7 or TIA PORTAL. 

If you use TIA PORTAL, you can have compatibility problems with older S7-300 communication modules series (In addition legacy STEP7 software may be compulsory).
 

The solution we found was using s7nodave driver, which fits any TCP communication module, including that of the controller module itself, as well as any STEP7/TIA PORTAL version.

Objet: Siemens S7-300 PLC and EPICS

Hey all,

for the vacuum system of our tracking detector we want to use a PLC. We
decided to use a Siemens S7-300 which should control the pumps, gauges
and valves of our system.

The main question now is how to connect the PLC to our EPICS system?
I've seen that the CPU module has PROFINET or PROFIBUS DP interfaces. Is
there a device support available for those? Is there a better/easier
interface available maybe via an additional communication processor?

Any feedback appreciated!

Best regards,

Florian
