Figure 78: Error message coding
Example of a module error:
•
The I/O LED starts the error display with the first blinking sequence
(approx. 10 Hz).
•
After the first break, the second blinking sequence starts (approx. 1 Hz):
The I/O LED blinks four times.
Error code 4 indicates "data error internal data bus".
•
After the second break, the third blinking sequence starts (approx. 1 Hz):
The I/O LED blinks twelve times.
Error argument 12 means that the internal data bus is interrupted behind the
twelfth I/O module.
The thirteenth I/O module is either defective or has been pulled out of the
assembly.
