GPIO Signals
The sbRIO-9687 GPIO signals are unidirectional. The signals can only be read by the GPIC.
On the inverter side, the signal has a pull-up to 24 V for SKiiP 4, Semikube GB, Semikube
GD, Semikube SL GD inverters, and it is open collector for SKiiP 3 GB and SKiiP 3 GD
inverters. The following figure is a schematic diagram of the GPIO signals.

The GPIO signals can be read on one of the sourcing digital input lines. The following table
shows the mapping between inverter GPIO signals and GPIC sinking digital input.
