The desired string assignment is generated and saved for
commissioning. In this way the appropriate addresses are
assigned to the connected CPI modules.
Save the string assignments as follows:
1. Leave the power supply for the CPV Direct switched off for
the time being.
2. Make sure that the CPI cables are fastened properly with
the union nut.
3. Switch on the power supply for the CPV Direct and, if
necessary, for the CPI/CP modules with load voltage
connection.
The fault LED P on the CPV Direct will flash if CPI/CP
modules are connected or if the string assignment is
modified.
4. Use a small screwdriver or similar tool to press the SAVE
button for at least 1 s (see section Fig. 1/3).
This will save the current string assignment as the nom
inal string assignment in the CPV Direct.
The fault LED Pno longer flashes.
The status LEDs of all the recognized CPI/CP modules
light up.
5. Power OFF/ON
Note
After saving the string assignment, check the address
assignments of your CPI system before starting user
programs.
