Example
The following example shows the comparisons made and the results provided
for MCMP(19). Here, the comparison is made during each cycle when 00000 is
ON.

COMPARE – CMP(20)
Cp1: First compare word
IR, SR, AR, DM, HR, TC, LR, #
Cp2: Second compare word
IR, SR, AR, DM, HR, TC, LR, #
Ladder Symbols
Operand Data Areas
CMP(20)
Cp1
Cp2
Limitations
When comparing a value to the PV of a timer or counter, the value must be in
BCD.
Description
When the execution condition is OFF, CMP(20) is not executed. When the exe-
cution condition is ON, CMP(20) compares Cp1 and Cp2 and outputs the result
to the GR, EQ, and LE flags in the SR area.
Precautions
Placing other instructions between CMP(20) and the operation which accesses
the EQ, LE, and GR flags may change the status of these flags. Be sure to ac-
cess them before the desired status is changed.
CMP(20) cannot be used to compare signed binary data. Use CPS(––) instead.
Refer to 5-17-8 SIGNED BINARY COMPARE – CPS(––) for details.
