7-8 Genius Modular Redundancy Flexible Triple Modular Redundant (TMR) System
User’s Manual – March 1995
GFK-0787B
Example:
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:
16 x 6 = 96 words required.
If the Analog Input Table had a configured length of 1024, these inputs would be
located in the table as shown below..

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 Output Addressing
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.
