tModular Redundancy Flexible Triple Modular Redundant (TMR) System 

An application has sixteen analog input groups (each of which is a 6–input group),
including spares. The total number of analog inputs from these blocks would be:

If the Analog Input Table had a configured length of 1024, these inputs would be
located in the table as shown below..

Voted Analog  Inputs = 96

Bus “C”  inputs = 96

Bus “B”  inputs = 96

Bus “A”  inputs = 96

Available for single

Genius  analog  inputs

or other use

As with discrete inputs, all of the analog inputs are available to the PLC application program.

Analog blocks with outputs can be used in a GMR system, but they do not operate in GMR
mode.

They can be configured for Hot Standby CPU redundancy operation. In Hot Standby mode,
an analog block accepts outputs from a bus controller at serial bus addresses 31. If that bus
controller stops sending output data, the block accepts outputs from bus controller 30.

Remember that each PLC in the GMR system normally executes the same application
program.
