3-32 Functional Blocks
Output Ranges
•
CVEUHI and CVEULO define the full range of CV in engineering units. If this block has a secondary, it brings the
secondary’s input range through the BACKCALC and sets its CV range to that. If it has no secondary, CVEUHI and
CVEULO track its own input range (XEUHI and XEULO).
•
OPHILM and OPLOLM define the normal high and low limits for OP as a percent of CV range; these are
user-specified values. OP clamps to these limits if algorithm’s calculated result (CV) exceeds them or another
function block or user program attempts to store an OP value that exceeds them. However, an operator may store
an OP value that is outside these limits.
•
OPEXHILM and OPEXLOLM define the extended high and low limits for OP as a percent of the CV range. These are
user-specified values. Operator is prevented from storing an OP that exceeds these limits.
