10.1.2.12 Internal faults
F062 Fault in parameter memory
(active in all operating states)
Software monitoring of correct functioning of the EEPROM module (non-volatile memory) on the A7009 board.
The EEPROM values contains all data which must be protected in the case of a power failure (i.e. parameter values and process
data which must remain stored during power failures).
The following are monitored:
• Connection between the A7001 electronics board and the EEPROM on the A7009 backplane wiring assembly
• Whether the parameter values stored on the EEPROM are within the permissible value range
• Whether data are being correctly stored on the EEPROM. For this purpose, values are read and checked for correctness
after they are transferred to the module
• Whether the checksum of the non-volatile process data in the EEPROM is correct
Possible causes for all fault types:
Excessive EMC-related interference is present (e.g. due to unprotected contactors, unscreened cables, loose shield
connections)
