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.

Hello,

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.

Hello everyone

I also encountered the same problem (causing customers' troubles)
Is the communication cable too long? Is it the power cord of the device or the power cable of the HMI?
The environment is too noisy? Is there usually a decibel that regulates the use environment?
I changed Porter? How do I change it?
Is there any other way to improve?

That is generally caused by noise in the system somewhere usually coming in on the I/O wires.

How long has this system been in use?  Do you have VFD's connected?  Large inductive loads such as contactors or solenoids?

Joe's ask is a critical question that needs to be answered asap.  The relevance is "did it work OK before, and if so, how long before the gremlins appeared?"

Dear Joe

The system has been in use for half a year.
There are also links to VFD
Ok, I will check the noise.
Thanks to JOE for your support.

And did the use for half a year have the problems all the time, or have they only just started happening?
