4 Instructions 4.3.1 Contact Comparison
Use the 32-bit instruction ANDD
☼
to compare 32-bit counters (C200–C255). If a different instruction is
used, an error will occur.
OR
☼
: Data comparison
◆
Overview
The OR☼ instruction compares two operands and outputs the comparison result as a logical state. The
variables in comparison are processed as signed numbers.
OR
☼
S1 S2
Parallel contact
data comparison
Applicable model:
H3U
S1 Comparand 1 Data source to be compared or data variable unit 1
16-bit instruction
(5 steps)
OR=: Continuous

32-bit instruction
(9 steps)
ORD=:

S2 Comparand 2 Data source to be compared or data variable unit 2
The
☼ comparison operator can be =, >, <, >=, <=, or <>.

OR= 240 ORD= S1 = S2 S1 ≠ S2
OR> 241 ORD> S1 > S2 S1 <= S2
OR< 242 ORD< S1 < S2 S1 >= S2
OR<> 244 ORD<> S1 <> S2 S1 = S2
OR<= 245 ORD<= S1 <= S2 S1 > S2
OR>= 246 ORD>= S1 >= S2 S1 < S2
Example:
[OR= D2 D4]
(M20)
[OR>= D6 K123]
ǒSET Y10Ǔ
M10
M20
M20 = ON when M10 = ON or D2 = D4.
Y10 = ON and remains in this state when
M20 = ON or D6 > K123.
Use the 32-bit instruction ORD ☼ to compare 32-bit counters (C200–C255). If a different instruction is
used, an error will occur.
