COMP CNST, ANY, ALL, & DELAY CNST
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.
COMP CNST
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 (Field
C relational qualifier) to the number in Field D (see Figure 8-28). The choices
for Fields B, C, and D are as follows:
• Field B Analog Pseudo points 21-01 through 21-25 (20-01 through
20-07 are system Analog Pseudo points)
• 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)
[COMP CNST] [20-01] [EQ] [00001]
Figure 8-28
Example: When the value of the Analog Pseudo point equals 1, then
execute the output.
