The following shows the functional block diagram of the DI (digital input) and internal contact:
Handling Precautions
Even though three internal contacts 1 to 3 are provided, the number of
digital inputs determined by the optional model is 0 to 2 points.
With the default settings before shipment, the operations of digital input 1
to 2 have already been connected to internal contacts 1 to 2.
To utilize the operation of internal contact 3, it is absolutely necessary to
set the DI Assignment.
