On board IO codes


Recommended Posts

Hi engineers,

I'm working with a US5-B5-RA28 PLC, i would like to known the meanings from "On board IO.IO" error codes, cause i'm facing some issues with this plc model. 

This PLC is running but sometimes the PLC gets On board IO.IO Status = 16 , after that all the digital outputs are freeze with their last state and the analog signals have wrong values, but the HMI go on working OK

Any ideas? Thanks
