Digital Output Signals
The PFDD robot provides 8 general-purpose optically isolated digital output signals in the 25-pin D-Sub
connector on the facilities panel.
These output signals can be individually configured as "sinking" or "sourcing" by means of a software
setting. (See above.)
As shipped from the factory, the output signals are configured as "sourcing"
,
i.e. the external equipment must pull down an output pin to ground and the controller pulls this pin to
24VDC when the signal is asserted as true.
