Hi Delphoe , chech in SFC properties please. Maybe you can see "autostart" box checked? if not, can you post some screenshot about SFC properties or CFC link P.S.: there is an working example program for SIMATIC Batch application in PCS7. Have a look for "zen33_01.zip"usually located in "C:\Programmi\SIEMENS\STEP7\examples", and look "SIMATIC BATCH - Getting Started" manual in PCS7 documentation. It explain very well a lot ofabout SIMATIC BatchApplication Regards |

Hi Delphoe ,
SFC properties in Autostart means CFC will start itself when plc goes from STOP to RUN (only if SFC is in manual mode too)
When Batch is turned in manual mode means it will not start the step that follow the step just completed; for example: 1) Operator swith batch in manual mode (operation reportend in Opeartor List Messages) 2) Step in progress completed 3) The following step it will not start (Batch doesn't give the start command to next step)
Switch Batch in manual mode doesn't means switch SFC Type in manual mode. SFC Type workc indipendent from Batch status (only start/stop/pause/abortcommand exchange from Batch & SFC) Switch SFC Type in manual mode means Batch will give error/waiting message to allocate step when needed. All eventare recorded in message log, both from operator or automatic event, like start/stop/pause/abort command coming from plc logic. Regards |

Hi Delphoe , when you want manage SFC from faceplate or Engineering Station, need SFC in manual mode. when you want manage SFC from CFC logic, need SC in auto mode to use external command, like start/stop/pause/abort from Batch application, you still need SFC in auto mode. If your batch is still running means SFC never terminated/completed and put itself in IDLE status (with SFC in auto mode). That should be the reason Batch never teminated. Try to reset steps from Batch interface and restart again from there; you should be able to repeat last step/SFC and complete the Batch Regards |
