3. Set the IP address of the CN1 port on the backup CPU. Use default settings
(0.0.2.0 is added to the address of the primary CPU), unless your network
administrator requires otherwise. See IPConfig online help.
4. Start your 800xA Workplace.
5. Create a representation of the controller in the Project Explorer hardware tree.
Make sure the PM861/PM864/PM865/PM891 processor unit is defined as
redundant. See Control Builder online help.
6. In Project Explorer, set the IP address of the controller to the IP address of the
primary CPU. See Control Builder online help.
7. Switch on the secondary CPU. Check that you have communication with the
controller.
I/O Systems
There are several methods of connecting I/O systems to the AC 800M Controller:
• S100 I/O via CI856.
• S800 I/O units via the ModuleBus. Support for hot configuration during run,
redundancy on all levels, HART routing, and Sequence-of-Events (SOE).
• S800 I/O units via CI854/CI854A and CI840/CI840A, PROFIBUS DP.
Support for HART routing, redundancy on all levels, and hot configuration
during run.
If network redundancy is used, the IP address of the CN2 port of the primary
processor cannot be set using IPConfig . This address must be set in Control
Builder
If network redundancy is used, you also have to set the IP address of the CN2
port of the backup processor using IPConfig. See IPConfig online help.
There is no need to set IP address(es) for the backup CPU in Control Builder.
The IP address of the backup CPU, CN1 and CN2 ports will only be used for
internal communication between the primary and backup CPUs. When the
backup CPU takes over, it also takes over the primary IP address that is defined
in Control Builder. Other units on the control network will never notice the
switchover.
