Split from MM440, speed of a Motor through the MM440 VFD to PLC.

Hello Fast Track;

The S7-1200 CPU family would be a good combination of processing power and module flexibility. It is programmed with TIA Portal software, which is now at v.13.

You will find a few pages of module description from this link, with further pages showing the different S7-1200 CPUs and I/O modules; if you open the link to  the S7-1200 Special Modules you will find the various Siwarex loadcell modules that can be attached to a S7-1200 CPU.
