3.2.18 PLS
Definition
The PLS (programmable limit switch) block sets outputs or variables accordingly based
on the Encoder property. The Encoder property is typically the main axis position;
however, any variable can be used. A maximum of eight outputs can be programmed
per block. To control more outputs, connect PLS blocks together or assign additional
programs for the PLS function.
Properties
Encoder: The encoder/variable that determines the state of the outputs.
Typically this is the main axis position.
Maximum Position:
The greatest value of Encoder which sets the state of the output
according to the Output property.
Minimum Position:
The smallest value of Encoder which sets the state of the output
according to the Output property.
Output #: The output to be set when Encoder is within the range.
State: Select either ON or OFF. The output is set to this state when
Encoder is within the range, otherwise it is set to the opposite
state.
