Let me try to help you. I would like to get something clear first. 1. what type of connection do you have for hardware? Profibus gsd? Hardwire? 2. what is your local settings? should be 2. 3. I think MotL can be tripped by Signal code 16#0 too. you can try. You can test it in plcsim. can you take a picture on your faceplate to illustrate better? Hope it helps you. |

Dear PLC2011, Control error happens when the block sent stop signal but the feedback is still running with a monitoring time of MonTiDynamic (in your case, 20seconds) To have local mode control, you must first set to LOCAL mode first, but it seems like you are having manual mode now. Please see attached Link Page 1077 for MotL Modes. |

Dear PLC2011, The reasons I said Local mode is, you are using Start Local and Stop Local in your function block. I assume you are using hardwire signal. So to start the MotL in manual, first, the local Motor wiring design should set to remote. It is not possible to have both local and remote mode function together. Then, MotL in the faceplate, start, you should trigger 1 to start the motor, which output are you using to connect to output channel driver block? P_Start mean pulse start. I don't think you can function normally using P_Start. Then the Motor should return a feedback one 1 when the Start = 1. During this period, the motor should not be operable in Local. Hope this helps. |

Dear PLC2011, When something happened to the signal, you cannot stop the motor via the faceplate. So you trigger the stop command, the MotL “Start” change from 1 to 0, then the output is sending to the DO modules from 1 to 0, but now the motor did not react according to the stop command. I bet it relates to the external issue but not the function block issue. I hope I understand correctly. Did the signal quality change from 16#80 to 16#0? bad quality? which showing red spanner in the faceplate or block icons? And then when these kinds of issues happen, it happened only on one device or multi devices? Is the motor local remote wiring done correctly? any overcurrent settings which will cause the motor an issue? trip or something? Just brainstorming some possibilities for you. Hope it helps. |
