Syntax:
Label (LBL)
Operands:
Action:
The CMF command is a conditional module call. If the logic accumulator = 0,
the iTNC calls the module that begins at the label that you have entered. If the
logic accumulator = 1, the iTNC does not call the module. The CMF command
interrupts a logic sequence.
Example:
This example also applies to the CM and CMT commands.
Depending on the state of the input I5, call the Module 10. Initial state:
Input I5 = 0
Function
Load the operand content
into the logic
accumulator.
If logic accumulator =0,
