Hi Testermax ,
Could look strange to have blocks in same CFC belonging todifferent runtimegroup in same CFC, but not so strange. Depend of your choice. When dvelop SFC in slower RuntimeGroup your question disappear itself, no reason to be worried about execution time (because depends from slower execution - SFC). In your case, if i understood well, SFC read values from CFC located in previous runtime group, elaborate data, then writeSFC output to CFC block in previous runtime group, everything in same OB: that means you loose one SCAN cycle and nothing else (CFC elaborate SFC output data the next cycle). If you want optimize porgram elaboration it possible MANUALLY split FC block into 2 different runtime group whitout change CFC programming (or split CFC also - just your choice) At the end, Runtime group is a great instrument I checked and never used Regards |
