I/O Module Stuck-at Error (Channel Specific)

What does E3-524 mean?

A 'stuck-at' error has been detected on an I/O bus module for a specific channel. This indicates that a signal line or a logic gate within that channel is permanently fixed at a high or low state, preventing proper signal transmission or processing. This leads to incorrect I/O values.
