MC42FS Error code R4:2 1:1:3 I/O startup test failed

Gijs van Beek 4 weeks ago in Master modules / MC4x • updated by Gustav Widén (System support) 3 days ago • 1

Got the R4:2 1:1:3 I/O startup test failed error on a MC42FS module.

Even when I only put power (24v external power supply) and a address tag on it.
Tried to put an empty program on the controller. The controller is installing the program but when it restarts it keeps coming back with the same error.

Is there anything I can try to fix this?

A suggestion is to check the current capacity on the power supply.
