8.15.70 CALL MODULE IF LOGIC ACCUMULATOR = 0 (CMF)
January 2012
Syntax: CMF (CALL MODULE IF FALSE)
Operands: Label (LBL)
Action:
The CMF command is a conditional module call. If the logic accumulator = 0,
the control calls the module that begins at the label you have entered. If the
logic accumulator = 1, the control 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,
jump to LBL 10.
Resume main program
after module execution.
End of main program
