Addition of interface modules
You can only add the IM 460 and IM 461 interface modules, the external CP 443-5 Extended
DP master interface module or the relevant connecting cables when the system is de-
energized.
De-energized means that the power supply for an entire subsystem must be switched off.
This is only possible without affecting the process if the subsystem in question is in STOP.
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. Proceed as follows if you want to expand the subsystem of what has been the standby
CPU:
– Switch off the power supply to the standby subsystem.
– Insert the new IM460 in the CPU and establish the link to a new expansion unit
or
– Add a new expansion unit to an existing line
or
– Plug in the new external DP master interface and establish a new DP master system.
– Switch the power supply to the standby subsystem back on.
