Description
Precautions
The branching structure of this diagram is important in order to ensure that
000200, 000201, and 000202 are controlled properly as the timer counts down.
Because all of the comparisons here use the timer's PV as reference, the other
operand for each CMP(020) must be in 4-digit BCD.

Cp2
When the execution condition is OFF, CMPL(021) is not executed. When the ex-
ecution condition is ON, CMPL(021) compares the eight-digit content of Cp1+1
and Cp1 to the eight-digit content of Cp2+1 and Cp2 and outputs the result to the
GR, EQ, and LE Flags in the Auxiliary Area.
CMPL(021) is an intermediate instruction, like CMP(020). Intermediate instruc-
tions are entered between conditions or between a condition and a right-hand
instruction. Intermediate instructions cannot be placed at the end of an instruc-
tion line.
CVM1D CPUs are equipped with a similar non-intermediate instruction:
CMPL(029).
Constants are expressed in eight digits.
When comparing a value to the PVs of timers or counters, the value must be in
BCD.
Placing other instructions between CMPL(021) 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.
Note Refer to page 101 for general precautions on operand data areas.
