B. Parameters and data of the CPX terminal
System parameters: System start
Function no. 4402
Description With this parameter you can determine the start−up reaction of the CPX terminal
and save all current parameter settings and the current CPX equipment status.
Bit Bit 6
Values System start
Bit 6 Description
0 System start with default parametrizing (factory set
ting) and current CPX equipment status; external
parametrizing is possible (presetting)
1 System start with saved parametrizing and saved CPX
equipment status; parameters and CPX equipment
status are saved remanently; external parametrizing is
blocked; the M−LED on the field bus node lights up.
Note If bit 6 is set to 1, the current parameter settings will be frozen" (write−pro
tected) and the current CPX equipment status will be saved, except for bit 6 itself
and the module parameter Force channel X".
Recommendation: Select System start with default parametrizing and current
CPX equipment status". The desired parametrizing can then be created in the
start−up phase or after field bus interruptions e.g. by the plug−in module or the
scanner/bus master (depending on the field bus used). If System start with
default parametrizing and current CPX equipment status" is active, the factory
settings for all module and system parameters will become valid after Power On.

This parameter does not exist with the CPX−FEC in the operating modes Stand Alone and Remote
Controller (control function active).
