4.1.3
Save parameter settings
If parameter settings are changed in the controller, those changes will be lost after mains switching
of the controller unless the settings have been saved explicitly.
Manual saving of parameter settings
The
= "1: On / start" device command saves the current parameter settings safe against
mains failure to the memory module of the controller.
Automatic saving of parameter changes
When you select "1: active" in
, automatic saving is activated and every parameter change
is saved automatically in the memory module. Thus, manual saving of parameter sets is not re-
quired anymore.
4.1.4
Importing EPM data
The
= "1: On / start" device command activates the automatic import of parameters
from the memory module after the error message "PS04: Par.set incompatible".
= "0: Off / ready" device command deactivates this function again.
Note!
How to prevent a data loss:
• Do not switch off the supply voltage during the saving process.
• Only unplug the memory module if the device is switched off.
Stop!
Activating this function is not permissible if parameters are changed very frequently
(e.g. in case of cyclic writing of parameters via a bus system).
The maximum service life of the memory module amounts to one million writing cycles.
Make sure that this value will not be reached.
