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.
You have various opportunities to prevent a data loss by saving the parameter settings in the me-
mory module:
Quick saving of all parameters at the push of a button
( 23)
Automatic saving of parameter changes
Manual saving of parameter settings
Automatic saving of parameter changes
When you set the selection "1: Active" in C141/1
, the automatic saving function is activated and
every parameter change is automatically saved in the memory module. Thus, manual saving of pa-
rameter settings is not required anymore.
Manual saving of parameter settings
The C002/7
= "1: On / start" device command saves the current parameter settings safe against
mains failure to the memory module of the controller.
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.
