Chapter 2 Instructions
CMP instruction compares the contents of the internal register with the value speci-
fied by the operand, and turns ON/OFF the special utility relays (2009, 2010, 2011)
according to the result of comparison.
Comparing the current value of the counter and CMP value
1) Output relay 0500 turns ON when the counter value is smaller than "1000" (C001
< #01000).
2) Output relay 0501 turns ON when the counter value is equal to "1000" (C001 =
#01000).
3) Output relay 0502 turns ON when the counter value is greater than "1000" (C001
> #01000).
4) Output relay 0503 turns ON when the counter value is equal to or greater than
"2000" (C001 ≥ #02000).
