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

Ladder Symbols
CMP(20)
Cp1
Cp2
When comparing a value to the PV of a timer or counter, the value must be in
BCD.
When the execution condition is OFF, CMP(20) is not executed. When the
execution condition is ON, CMP(20) compares Cp1 and Cp2 and outputs the
result to the GR, EQ, and LE flags in the SR area.
Placing other instructions between CMP(20) and the operation which ac-
cesses the EQ, LE, and GR flags may change the status of these flags. Be
sure to access them before the desired status is changed.
