4.4.2.1. Example
The following example program illustrates how arguments can be specified
by variables.
In the program, a sequence of movements is performed. The motion
characteristics of each movement are dependent on the value of the digital
inputs. For each combination of digital inputs, a different set of values are
assigned to the variables that set the motion characteristics.
The main part of the program (lines 8 to 16) sets the profile velocity and
initiates motion. Once a pre-specified position has been passed, the speed
is reduced. Once the commanded motion has ended, a second motion back
to the origin is started. 500 ms after the second motion has ended, the
program restarts.
Most of the commands used in the main section use variables to specify the
value of the arguments. Depending on the initial state of the inputs, the
program calls (in lines 4 and 6) a different subroutine The variable values
are set under labels 3 and 4.
