Installing and connecting up the CP
The steps for installing and connecting up the CP are explained below.
1. Turn off the power supply when you have configured the CP for PROFINET IO
communication.
Note
CP as PROFINET IO controller when used with a CPU version < V6.0
If you operate the CP as a PROFINET IO controller with a CPU version < V6.0, note the
following points during installation with respect to the power supply:
When using the CP in the central rack or in a universal rack operating as central rack, you
should not insert or remove the CP when the power is on. If you remove the CP when the
power supply is on, the CPU changes to STOP and indicates "I/O error".
After inserting the module with power applied, it is essential to turn the power supply off
and on again.
Note:
If the CP is operated without PROFINET IO, it is possible to insert and remove the CP when
the power is on without affecting the CPU.
2. Plugging in the CP:
Fit in the CP onto the rack from the top and push it in at the bottom.
Note
Racks / suitable slots in the rack
• The CP can be plugged into all racks with slots for P and K bus connection.
• With the exception of the slots reserved for the power supply, the CP can be operated
• When using the universal rack UR1 or UR2 as an expansion rack, a communication bus
3. Secure the CP with screws.
4. Turn on the power supply.
5. Connect the CP to Industrial Ethernet via one of the RJ45 jacks.
Note
Operation with security on the external network
Make sure that the interfaces function correctly if you use the Security function of the CP.
If you use the security function of the CP, only connect the gigabit interface port X1P1 to
the network after the configuration with security enabled has been loaded.
You can find connection examples in the general Part A of this manual /2/ (Page 103).
6. Where necessary, connect other components to the remaining free RJ45 jacks.
Result: The CP is installed in the rack and the interfaces have been networked.
