Hello! I have a problem with Modbus RTU on my S7-1200 with CB1241 module. Once a day modbus sequence freezes (Modbus_Master is busy and my sequence identifier #i stopped changes). After several times "Stop CPU" -> "Run CPU" sequence continues successfully. I can not find mistake in my modbus sequence. Is it possible to reinitialize CB1241 or Modbus sequence or something like this to fix this problem. For example: if #i is constant for 5 second -> Reinitialize CB1241. My modbus sequnce in attachment to this post. Thanks for any suggestions. S7-1200: 6ES7 212-1HE40-0XB0 Firmware version: V4.2 CB1241: 6ES7 241-1CH30-1XB0 Firmware version: V1.0 Modbus_Comm_Load V3.0 Modbus_Master V2.4 Tia Portal v.14 AttachmentModbus_Sequence.pdf (269 Downloads) |
