Logical Operations
Type Operator Example Explanation
Logical product AND 001AND002 When channel 001 = 0 and channel 002 = 0, 0
When channel 001 ≠ 0 and channel 002 = 0, 0
When channel 001 = 0 and channel 002 ≠ 0, 0
When channels 001 and 002 ≠ 0, 1
Logical sum OR 001OR002 When channel 001 = 0 and channel 002 = 0, 0
When channel 001 ≠ 0 and channel 002 = 0, 1
When channel 001 = 0 and channel 002 ≠ 0, 1
When channels 001 and 002 ≠ 0, 1
Exclusive OR XOR 001XOR002 When channel 001 = 0 and channel 002 = 0, 0
When channel 001 ≠ 0 and channel 002 = 0, 1
When channel 001 = 0 and channel 002 ≠ 0, 1
When channels 001 and 002 ≠ 0, 0
Logical negation NOT NOT001 When channel 001 = 0, 1
When channel 001 ≠ 0, 0
Bit Output (Firmware version R3.03 or later)
Type Operator Example Explanation
Bit output * BIT C001BITB02 When bit 2 (LSB = 0) of communication input channel
C001 is 1, the computed result is 1. When bit 2 of
C001 is 0, the computed result is 0.
* If data is 0 or negative, the output value is 0.
