Failed Max Wait Run

What does E3-16128 mean?

The I/O bus module failed to complete its maximum allowed wait run time. This indicates a significant delay in processing or a communication deadlock, potentially causing I/O operations to time out and impacting system responsiveness or control. It suggests a performance or communication bottleneck.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Monitor the execution time of critical I/O operations and optimize application logic if necessary.

2. 4

   Consider replacing the I/O module if performance issues persist and cannot be attributed to configuration or load.
