5.2.3 Error numbers
Detailed information on module−specific diagnosis can be
found in the manual for the relevant module.
Possible faults of the CPX terminals are divided into three
error classes with different priority depending on the seriousĆ
ness of the fault. If a fault occurs, the system error LED
(SF LED) will flash depending on the error class.
Error class Flashing sequence of the
SF LED Error weighting Priority
1 1 * flashes, pause time Simple (e.g. simple user fault) low
2 2 * flashes, pause time Medium (standard diagnosis
and extended diagnosis) medium
3 3 * flashes, pause time High (hardware fault/internal
fault) high
Tab. 5/7: Error classification
If several errors occur together, the error with the highest
priority will have precedence. This means that:
ć The system error LED flashes according to the higher
priority
ć The number of the error with the higher priority will be
entered in the system diagnostic data under function
number 1938 (error number).
Within an error class, errors of modules with a lower module
number have higher priority, e.g. errors of module number 0
have the highest priority within a specific error class. Errors of
module number 1 have the second highest priority, etc.
