Removal of interface modules

Always switch off the power before you remove the IM460 and IM461 interface modules,
external CP 443-5 Extended DP master interface module, and their connecting cables.
Always switch off power to an entire subsystem. To ensure that this does not influence the
process, always set the subsystem to STOP before you do so.
Procedure
1. Carry out the required changes/additions and update the configuration in HW Config
accordingly.
2. Click "Download to module" in HW Config.
3. Select "Download station configuration in RUN mode".
4. Select one of the redundant CPUs.
5. Select "Automatically continue".
The initial processing steps of the plant change are
performed automatically.
6. Click "Continue".
– The CPU is selected
– The standby CPU may be switched to RUN by a warm restart.
– The required system data blocks are generated.
– The selected CPU is switched to RUN.
– The new hardware configuration is downloaded to the CPU.
7. End the H-CiR wizard.
As you can only add the IM 460 and IM 461 interface modules, the external CP 443-5
Extended DP master interface module and the relevant connecting cables when the
system is de-energized, you can no longer use the H-CiR wizard from this point.
8. Follow the steps below to remove an interface module from the subsystem of the standby
CPU:
– Switch off the power supply of the standby subsystem.
– Remove an IM460 from the central unit.
– Remove an expansion unit from an existing line.
– Remove an external DP master interface module.
– Switch on the power supply of the standby subsystem again.
