Would be it enough to provide the communication with a CU320? That is the question…

You would need to control the drive via hardwired IO if you wish to use this module. Who knows though maybeSiemens will release a Profibus Master or Profinet IO controller for the S7-1200 in the future. In the meantime why not look at the ET200S CPUs for a small footprint PLC to control a CU320.

I for one doubt very much thatS7-1200 hasProfinet I/O controllercapability butwould love to stand correctedwhen the offical manual/technical data sheets are released. The information that is available on the Siemens onlylists S7 communication protocol capabilty via the onboard ethernet interface (i.e. you can talk to other S7 PLC's and HMI's). Cheers Fritz

To make matters worse, Siemens has - for reasons that shall forever elude me -dropped STL as a programming language for S7-1200 (only LAD and FBD can be used, not too sure what is going with Siemens butI for one am starting to get concerend).

Idoubt it, S7-200 never had this ability nor werethese little "suckers" meantto have lots of (distributed) I/O stations but instead aimed at the small machine market. Anyway,I don't really care to be honest. Let's face it who would want to program them if they don't have STL available? schnek ...about the STL, I hope the same will not happen to the new series of S7-300 and S7-400... Me too (or otherwiseI will need to consider acareer change). Cheers Fritz
