Figure 27 - PLS Values
In this example, the PLS variable is given a dimension of [1..4]. This
means that the HSC can have four pairs of High and Low Presets.
Once again, your High Presets should be set lower than the OFSetting
and the Low Preset should be greater than the UFSetting. The
HscHPOutPut and HscLPOutPut values will determine which outputs
will be turned on when a High Preset or Low Preset is reached.
2. You can now build and download the program into the controller then
debug and test it following the instructions for the last project.
Forcing I/Os Inputs are logically forced. Status indicators do not show forced values, but the
inputs in the user program are forced.
Forcing is only possible with I/O and does not apply to user-defined variables
and non-I/O variables, and special functions such as HSC and Motion that
execute independently from the User Program scan. For example, for motion,
Drive Ready input cannot be forced.
Unlike inputs, outputs are physically forced. Status indicators do show forced
values and the user program does not use forced values.
