OR#: OR contact status bit operation
◆
Overview
Whether the OR# instruction is enabled is determined based on the bit logical operation result (a node
connected to another node in parallel).
OR# S1 S2
OR contact status
bit operation
Applicable model:
H3U
S1 Data 1 Element number of source data 1 16-bit instruction (5
steps)
OR#: Continuous

S2 Data 2 Element number of source data 2
Note: The # comparison operator can be &, |, or ^.

Function
A logical operation (AND: &; NOT: |; XOR: ^) is performed on [S1] and [S2]. The instruction is enabled if the
operation result is not 0; if the operation result is 0, the instruction is disabled. The execution results are as
follows:
16-bit Instruction 32-bit Instruction
Enabled State
Condition
Disabled State
Condition
OR& ORD& S1&S2 ≠ 0 S1&S2 = 0
OR| ORD| S1|S2 ≠ 0 S1|S2 = 0
OR^ ORD^ S1^S2 ≠ 0 S1^S2 = 0
