3.In a redundant CPU system, RCMs cannot be configured in expansion racks.

4.Rack 7 cannot be seen nor edited.

Redund Type

This parameter specifies whether the CPU is configured as the primary controller or the secondary controller. The Redund Type has three possible choices: PRIMARY, SECNDARY, or SIMPLEX. The default value is PRIMARY.

When this configuration item is set PRIMARY, all configured redundant Genius Bus Controller(GBC) Serial Bus Addresses (SBA) must be 31. If any one of the SBAs is not 31, the message ºSBAs of all redundant GBCs in a primary system must be 31: modify (Y/N) ?. Answering ºYº automatically changes all SBAs to 31. Answering ºNº leaves this field unchanged.

When this configuration item is set to SECNDARY, all configured redundant Genius Bus Controller(GBC) Serial Bus Addresses (SBA) must be 30. If any one of the SBAs is not 30, the message ºSBAs of all redundant GBCs in a secondary system must be 30: modify (Y/N) ?.º Answering ºYº automatically changes all SBAs to 30. Answering ºNº leaves this field unchanged.

The third choice is SIMPLEX, which is currently not a valid mode for the CPU 780. You can configure the Redund Type for SIMPLEX, but the choice will be rejected when you attempt to STORE the configuration.

Background Window

The default for this parameter for CPU redundancy systems is 5 ms (limited Window mode). The background window runs several diagnostic tests which can be disabled by setting the the background window time to 0. These tests are run in Constant Window and Constant Sweep mode only if the window/sweep time is large enough.

Normal Sweep Mode

The Sweep Mode for the redundant CPU has to be selected. Below is the detail screen (page 2) of a redundant CPU configured for NORMAL sweep mode.
