As a rule, limit value monitoring for those components to be measured by
the gas analyzer is factory-set. This requires that there be enough digital
outputs on the I/O modules to handle the number of sample components.
Note: Limit value monitors are factory-set or user-configured Limit Monitor
function blocks. The Technical Information "Function Blocks – Descriptions
and configuration" contains complete information on the individual function
blocks.
