MSG_Modbus block Error ID21 in Micro850

Started by sonia, 20 Aug 2014

Posted 20 Aug 2014

Hi Everyone, I am using the block MSG_Modbus RTU in a Micro850 Allen Bradley PLC to read data from an OMRON PLC via modbus. The Allen Bradley PLC is the master. As I want to start the block operation I am getting a error code ID55 that says from the manual: "The message timed out in the local processor. A link layer timeout." Is there something to do with the modbus mapping? Can anyone please assist on this issue? Sonia
