The COMP CNST (Compare Constant), ANY, ALL, and DELAY CNST input
condition qualifiers are two-stage qualifiers. Additional programming is
necessary in order for these qualifiers to work correctly. When selecting these
qualifiers, you must press Enter to program the second stage. In this second
stage there are four additional fields with the following choices: Analog Points,
numbers, relational qualifiers, and Lists. The choices for the different fields are
related directly to the qualifier selected.
When using the input condition qualifier COMP CNST, a statement is true when
the value of the Analog Pseudo point in Field B is the proper relationship
(dictated by the Field C relational qualifier) to the number in Field D (see Figure
3-27). The choices for Fields B, C, and D are as follows:
• Field B – Analog Pseudo points 20-01 through 20-25 (20-05 through 20-25
are reserved for future use)
• Field C – Relational Qualifiers EQ (Equal), NE (Not Equal), GT (Greater
Than), LT (Less Than), GE (Greater Than or Equal), and LE (Less Than
or Equal)
• Field D – Number Value (00000 to 65535)
