2.2.2 Parametrizing the CPX terminal with STEP 7
2-26
When the PROFIBUS system is switched on, the "start
parametrizing" of the CPX terminal is undertaken by the para-
meter set 1 saved in the PROFIBUS master. The field bus
node then distributes the parameters module-orientated to
the CPX modules 2.
Please note
After each interruption of the field bus system (e.g. after
interruption of the power supply to the field bus node), the
parameter set will be sent again by the PROFIBUS master
to the field bus node.
An exchange of individual CPX modules is therefore possible
without the need once again for manual parametrizing.
System parameters
1. Double click the symbol of the CPX terminal on the
PROFIBUS line 1 (see Fig. 2/9).
The dialogue window "Properties - DP slave" appears 2.
2. Select the register "Parameter assignment" 3.
The list with the parameters and the present active values
will be displayed.
3. Click the value of the parameter you wish to modify.
A dropdown list with the possible values will open up 4.
