I am trying to configure a simple Modbus RTU message and I am getting an error status of 16# 8281 on the Modbus Master block. I have searched both the forum and the S7-1200 manual, but I cannot find this error code.
I attached the program. Does anyone see what I am doing wrong? Thank you in advance. AttachmentModbus Test.zip (1176 Downloads) |

Dear Saint Germain This is regarding Error (Status) 8281 Again. In your last conversation you havent updated weather your problem has solved or not?? As i am getting same problem,implemented remedy suggested by "Sion".. """" Hi , I also faced a problem when i was unsing the Modus RTU blocks V3.0 My problem was fixed when i changed the Static parameter Mode to the value 4 in the Modbus_Comm_Load_DB. The value 4 means that you are working with the Modbus protocol. To be shore i move the value 4 to the " DB Modbus_Comm_Load_DB . Mode " at First Scan. I hope this was helpfull. Greatings"""" Still My problem is not solved.Please help. |
