Configuring the Redundancy CPU for Non-redundant Operation

he Redundancy CPU can be used for both redundant and non-redundant applications. For non- redundant applications, do not configure Redundancy Communications Modules in the system. If a Bus Transmitter Module is configured set the Remote RCM Present parameter to NO. Keep all redundancy-related parameters in their default settings.

Genius I/O in the non-redundant system can be configured for either no redundancy or externally paired. (If a GBC redundancy mode other than RED CTRL or NONE is selected, it will be necessary to select the GDB control strategy. When that is done, the programmer may display messages that %Q and %AQ must be included in the data transfer. These warnings can be ignored when configuring the CPU for non-redundant operation).

Rack Module Configuration Parameters

Interrupts cannot be ENABLED when the configured CPU is a Redundancy CPU. When a redundant CPU is configured, any interrupts enabled in the configuration are set to

DISABLED.

For redundant applications, a Bus Transmitter Module must be configured and its Remote

RCM parameter must be set to YES. (see the previous discussion for non-redundant

Tapplications.)

For redundant applications, a Redundancy Communications Module must be configured in rack 0 of each system. For a given unit, the Local RCM is the one configured in that unit; the Remote RCM is configured via the Bus Transmitter Module's Remote RCM parameter. Remote RCMs appear as being in slot 1 of rack 7. (see the previous discussion for non-redundant applications.)

Bus Controller Configuration Parameters

When configuring the PRIMARY PLC, all Genius Bus Controllers configured for redundancy must have Serial Bus Address 31.

When configuring the SECONDARY PLC, all Genius Bus Controllers configured for

Tredundancy must have Serial Bus Address 30.

Non-redundant busses with a bus controller in only one of the PLCs do not need to use Serial Bus Address 31 or 30.

For single Genius bus networks, all Genius Bus Controllers in the system must be configured for RED CTRL Redundancy with the redundant pair set to EXTERNAL, or they must be configured for no redundancy.

For Dual Bus Genius networks, all Genius Bus Controllers must be configured for Dual

Bus/Redundant Controller (DB/RC).

(It is possible to configure bus controllers in a Redundancy system with Redund Type set to NONE, but this bypasses some important integrity checks, which are desirable for optimum system operation).
