Assignment can vary depending on the version of firmware of the sensor control unit.
* Applies to DMS2 only.
Memory of number of induced warnings and errors
– For all ascertained warnings and errors, DMS2.ED uses counters of occurrence of these warnings and errors during
operation of the system.
– Values of the counters are stored to the EEPROM memory and are preserved even in case of the power supply fall-out.
– Reading of the counters is possible by means of the program for PC
– Clearing of the counters is possible by means of the program for PC with the level of authorization “SERVICE”.
Memory of recently induced warnings and errors
– DMS2.ED stores three recently induced warnings and errors to the EEPROM memory.
– Recent warnings and errors can be displayed and erased by means of the program for PC.
