You have to create a sequencer which is started when abort is pressed. And you can make one if stop is pressed. But you can also make one sequencer which is started when abort or stop is activated. For this you have to set the start condition of the sequencer. And in the sequencer you can create the logic to stop everything. If you press stop or abort, the SFC goes from Run to Aborting (stopping) and then to Aborted (Stopped). In order to restart the SFC again, you have to set the SFC to Idle before you can start the SFC again. Please find enclosed the SFC OSL-> Operating State Logic. This is how a SFC responds to actions and you can see which states are possible. This is how the SFC operates.... |

AgrS, Please find enclosed (and in my next post) attachments. I think your start condition is not set correct. AttachmentSFC(1)1.pdf (506 Downloads) |

Hi Sorry for the confusion... In my example, the correct syntax should be: SFC(1).ABORTING = ABORTING, where SFC(1) is the SFC name and ABORTING is the output status of the SFC. You can even use input "ABORT" as well...numerous ways... This way, the SFC is set to ABORTING state, and then the sequencer is started and executes the logic. After that the SFC is automatically ended to aborted state. Hope this is clear? |

Well, in this case "Abort" means the signal = "1". If you are right clicking the sequencer on the left bottom of the screen and then select: Sequencer properties, it will take you to the correct screen where you can select the start condition.
No, this is not correct, you must get the start condition of the sequencer. You now have set 47SFC1_SEQ(1).ABORT = Abort to the step initialization. That is not correct, you must set this in the starting condition of your sequencer: "ABORT". Access this by right click on "ABORT" in the left bottom of the screen and then select: Sequencer properties. The sequencer will start when the SFC is in Abort and executes the steps in that sequencer |

Well, that is a counter block which I do not know off. But normally in a step you have a "Initialization", "Processing" and "Termination" sequence. When a step is activated, all commands under "Initialization" will be processed. Then the step is in the "Processing" step and executes all commands under "Processing". Finally, when the transition of the current step is fulfilled, the step is in the "Termination" sequence. So, if you want to count something, you can set Count=1 in the initialization and Count=0 in the termination. |

New question published by AGrS is split to a separate thread with the subject Where I could define an input byte. Best regards |

Also the counter does not work. What do I do wrong if I keep trigger and count_ok on 1 and give count a 1 at the end of my sequence and later make it 0 again? |

Hey AGrS! Please observe the SFC OSL. I think I attached this in one of my previous posts... It's the Operate State Logic for the SFC. In the diagram you can see that a Reset command is only valid when the SFC is in the ABORTED state. The SFC is then set to IDLE. The reset in your picture is connected properly. |
