Explanation of function and operation
1. 16-bit operation (CML and CMLP)
Each bit of a device specified as
is inverted (from 0 to 1 or from 1 to 0), and then transferred to
.
• When a constant (K) is specified as
, it is automatically converted into binary.
• This operation is useful when a logically inverted output is required as an output from a PLC.
