Changing alarm values in confi dialog of monitoring and controller function
A description of this resolution:
- Confi handling
- Carry out confi intervention in those functions that address the changed monitoring and controller function (e. g. sequence flow).
Carry out station reset. Thus coupling is effected anew.
This concept will not be changed.
"Changing alarm values in confi dialog of monitoring and controller function" resolves the following:
When entering or provisionally deleting alarm values in monitoring or controller functions in the confi dialog the system image addresses of all alarm amounts will shift within the configured function.
This affects functions addressing these alarm amounts since functions already coupled do remember the previous system image address.
Example: Writing on a wrong alarm value by a sequence flow.
The GH1 of a monitoring function is to be written on by a sequence flow. If then the GH2 in the monitoring function is deleted GH1 will move to another address. The sequence flow writes on another value (e. g. GL2) as far as available.
- Concerns all types of monitoring and controller functions in all firmware versions. Only concerns the alarm value amounts; Addressing with GH2…GL1; GDS, GDD, GHT, GLT, GW1…GW4.
The signal statuses (e. g. SH1, SH2 etc.) are not affected.
The underlying cause is:
- Principle of monitoring and controller function
