HMIGXU3500 04 Hex Error Code

ProjetosFortAutomação · ‎2024-06-04

Hello everyone. I'm having a trouble with almost every HMIGXU3500 we use in our machines. The device is connected to a TM200CE24R and an Ageon (Brazilian) Drive. The PLC is linked by RS485 and the drive is linked by a MODBUS cable. The problem is: the HMI is losing connection to the Drive and the Error Code 04 Hex pops up, but, in the Schneider support I could not find better explanation than "An unrecoverable error occurred while the server was attempting to perform the requested action." and I really need to solve this. We used to not have this kind of problem a couple months ago, but recently it got very frequent.

Thank you for your attention.

The HMI is the Modbus Client and the drive and the PLC are the servers? Did you use a resistor for termination on the Serial Line? Is the drive proper grounded? Did you use a shielded cable for modbus?
