Hi,

I'm using a CV of a SFC Type (A) to trigger start another sequencer of a SFC Type (B). This CV is connected to a PV and the PV is used as the Start Condition of the sequencer of the SFC Type B. It works as intended but I just couldn't control it (Hold/Stop/Abort). The triggered sequencer is running, but the Operating State is in IDLE. Did I miss out something? One condition is that the Operating Mode must be in MANUAL.

Hi,

you're using a pretty old-style approach. I'd recommend to use Technological Engineering for this. Then you can create an EMT for SFC type A (or EPHT if you want to see it in Batch) and add an EMT for SFC type B as a role.

With technological actions you can now pretty simple control the underlying EMT B from EMT A. I'd recommend to read the SIMATIC PCS 7 Process Control System Compendium Part C - Equipment Phases with SFC Types

 Hi Trivial,

Thanks for replying, I've read Compendium C but still don't know where to start with the EMT. Is there a better manual for this? I'm not using Batch by the way.
