4.3 Main routine
The Main routine consists of four rungs of ladder logic programming. A rung description
briefly describes the Input and Return (output) parameters of the JSR instructions for each
routine called. Temporary tags have been entered for each input parameter and each return
parameter. The tag names entered in the JSR’s are not declared. The user must replace
these tag names with existing project tags or create new tags. The routine will show an error
until all input and return parameters are satisfied. The input parameters may also be entered
as actual values. If an input parameter is set to a value and not a tag, the value cannot be
edited in run mode. Values entered directly in the JSR should be constants that do not
change during machine operation. Specific formatting is required for values entered directly
in the JSR.
NOTE: For Application Module users, the tags in the JSR’s are predefined and configured for
operation. No additional integration is necessary.
Data Type Format Example
B = Boolean x 0 or 1
I = Integer x 123
R = Real (Float) x.x 3.4 / 13.0
If any signal scaling is required to interface the FM into the user application, the user may use
the main routine for this programming. Note; Scaling for inputs to the routines should be
done before the JSR and any scaling applied to the return values from the routines should
be done after the JSR.
4.4 Logic Routine
The Logic Routine is used to configure the Tension Control Function Module. In this routine
the selected tension mode is tested, constants for speed and torque scaling are generated,
and sections of code are enabled or disable depending on the tension mode selected.
