Hello Everyone.

Hello everyone
I am having a problem with my Vision V350, in the company where I work there are two PLCs, a V350 and a V1210 that communicate by MODBUS. We have a screen that alerts us when a communication problem happen and when we check our V350 it shows us an error that is:

O.S. (Stop Mode - Fatal Error)

Enum: 0x00001740

IP: 0x00250000 00076A2C

Ldr: 0x000000DE

Desc: Undefined Opcode

Some changes had been made to the program and then this error arose so it went back to the previous program, but the problem is still happening.

Does anyone have any idea why this happens?

By performing a reset of the equipment, the problem is solved momentarily but this is not recommended for our production.

I had a similar problem some years ago with unican communication. The communication cable was too long, the environment was also too noisy, I changed the baud and purhased a Phoenix Contact CAN repearer.
