Configuration
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. Technical Bulletin “AO2000 Function Blocks – Descriptions and Configu-
ration” (publication number 30/24-200 EN) contains complete information on the
function block.
