Operands:
S
: Source of data
D
: Destination device
Explanations:
1. This instruction can be used for phase-reversed output.
2. Reverse the phase (0→1, 1→0) of all the contents in S and send the contents to D. Given that the
content is a constant K, K will be automatically converted into a BIN value.
Program Example 1:
1. When the user wants to perform the phase-reversed output operation, please use this instruction.
2. When X10 = On, b0 ~ b3 in D1 will be phase-reversed and send to Y0 ~ Y3.
