Timeout at read request

What does 12358 mean?
A read request to an I/O device or file timed out before the operation could complete, indicating that the system waited longer than the allowed period for a response. This IO_STATUS error suggests a communication issue, a slow device, or an unresponsive file system. The program will abort if the file_id is invalid.
Common Causes
- The I/O device or file system is slow, unresponsive, or experiencing high latency.
- Communication link issues such as damaged cables, improper termination, or network congestion.
- The timeout period for the read request is set too short for the expected operation duration.
- The file_id used does not correspond to a valid opened file, leading to an indefinite wait.
Repair Steps
- 1
Check the responsiveness and status of the target I/O device or file system through diagnostic tools.
- 2
Verify communication cables, connectors, and network settings for integrity and proper termination.
- 3
Adjust the timeout setting for the read request in the KAREL program if the device naturally has longer response times.
- 4
Use the KAREL command READ file_id(cr) to clear any existing IO_STATUS error condition.
