Hi, I am having an issue with Omron CJ2m Cpu32 serial communication. I'm not receiving the data from pc to plc. sometimes during the production. When I recycle the power its working fine. Is there any Flag to reset the Serial port and clear the buffer on Cj2m VPU32. I contacted tech support and they told me to use A526.00n to clear the port. But I think A528.00 is not for CJ2m cpu32. I'm new to Omron programming and serial communication any reply or response would be helpful. thanks in advance.

Pc is just a standard RS-232 (It parses the commands it is sent once it receives a CR/LF). No Host link/ Fins etc. Eg; For the PC to perform an inspection it is sent a 1 with a CR/LF and It responds with a 1 digit numeric code with a trailing CR/LF.

I don't see any external card on the plc please check the attached image.

Sorry I am using A526.00. I posted it wrong.
