Ok. Looks like PID it is not a problem for WAGO 750-833. Still have a doubt: In general, is it good idea to use WAGO PFC for a local control? Does it have Pass-through protocol? Would I be able to see and modify the code from my office through the Ethernet – SLC Profibuss Scanner – WAGO 750-833? As an alternative we can use AB cheapest Compact or Flex Logix and get rid of the WAGO at all. My company prefers AB, but cost is an issue. And for me WAGO looks like an elegant solution.
