2. 32-bit operation (DCML and DCMLP)
Each bit of devices specified as [
+1,
] is inverted (from 0 to 1 or from 1 to 0), and then transferred to
[
+1,
].
• When a constant (K) is specified as [
+1,
], it is automatically converted into binary.
• This operation is useful when a logically inverted output is required as an output from a PLC.
Program examples
1. When receiving an inverted input
The sequence program shown below can be written by CML instruction.
2. When four bits are specified for a device with digit specification
