Analog Discrepancy Reporting

When the GMR software compares analog input data, it checks each channel against discrepancy limits provided as a part of the configuration for that input group. Any channel that varies by more than a configurable percentage from the intermediate value is reported.

Discrepancy signals are filtered for a configurable time period, to eliminate transient discrepancies caused by timing differences.

Non-Voted Analog Inputs in GMR Input Groups

If a system includes analog inputs that do not require redundancy, they are usually located on individual analog blocks. However, they can also be located on channels of blocks in a GMR analog input group that do not require redundancy. For example, a group of three 6-channel analog input blocks might use only four voted inputs on each block. That would leave inputs 5 and 6 available for connection to other sensors not requiring voting.

Non-GMR Analog Blocks

Individualanalog blocks can be used as input blocks or combination input/output blocks. All of the operating features of these blocks are available.

Individual non-voted analog blocks can be included in the GMR configuration.
