Adding interface modules in PCS 7

Always switch off the power before you install the IM460 and IM461 interface modules,
external CP443-5 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. Change the hardware configuration offline (see section PCS 7, Step 2: Offline modification
2. Stop the standby CPU (see section PCS 7, Step 3: Stopping the standby CPU (Page 206))
3. Download the new hardware configuration to the standby CPU (see section PCS 7, Step 4:
4. To expand the subsystem of the present standby CPU:
5. Switch to the CPU with the modified configuration (see section PCS 7, Step 5: Switch to
6. To expand the subsystem of the original master CPU (currently in STOP mode):
7. Change to redundant mode (see section PCS 7, Step 6: Transition to redundant state
8. Modify and download the user program (see section PCS 7, Step 7: Editing and
210
of the hardware configuration (Page 205))
Loading new hardware configuration in the standby CPU (Page 206))
– Switch off power to the standby subsystem.
– Insert the new IM460 into the central unit and then establish the link to a new
expansion unit.
or
– Add a new expansion unit to an existing chain.
or
– Plug in the new external DP master interface, and set up a new DP master system.
– Switch on the power to the standby subsystem again.
