Hi folks, I am using Done and Error as condition to call the next Mudbus_master. After a while the communication stopped because one of the Modbus_masters got stuck on Busy. Does anyone know why this is happening? According to someone I talked to at the SIEMENS Support then this is not supposed to happen. The Blocked_Proc_Timeout is supposed to prevent this. This Blocked_Proc_Timeout is set default to 0.5 (I am guessing that is seconds.) How does this differ from the RESP_TO that you set in the Modbus_Comm_load? Because that is set default to 1000 (1s). In attachment (Download from WeTransfer) is a project where I am shifting between two devises. In NW3 I added a condition that if MB_master is busy for more 1s then it goes to next device. This seems to work but I don’t want to have it if there is a better way. Perhaps someone can send me a project they have done with multiple master block that works.

Hi, Can you attach the program once again? It has expired. |

I had faced a similar problem ( Busy bit gets stuck ). The TImer output is used reset and re-trigger communications. |
There is no such thing as the last bug in a program |

Hi Navnag. How do you go by reseting and re-triggering the communication? |

New question published by andersonpss is split to a separate thread with the subject How to reset Modbus_Master in the ET200SP. Best regards |
