Figure 58: Error message coding

Example of a module error:
•
The I/O LED starts the error display with the first flash sequence (approx.
10 Hz).
•
After the first pause, the second flash sequence (approx. 1 Hz) starts:
The I/O LED flashes four times.
Error code 4 indicates "data error internal data bus".
•
After the second pause, the third flash sequence starts (approx. 1 Hz):
The I/O LED flashes twelve times.
Error argument 12 means that the internal data bus is interrupted behind the
twelfth active I/O module.
The thirteenth I/O module is either defective or has been removed from the
network.
