X3: Digital inputs - general purpose DI1 & DI2
These general purpose fast digital inputs are buffered by an opto-isolator, allowing
the input signal to be connected with either polarity. When the MicroFlex e190 is
connected to Mint WorkBench, the digital inputs can be configured using the Digital
I/O tool. Alternatively, Mint keywords including RESETINPUT, ERRORINPUT,
STOPINPUT, FORWARDLIMITINPUT, REVERSELIMITINPUT, DRIVEENABLEINPUT,
MOTORTEMPERATUREINPUT,PHASESEARCHINPUT and HOMEINPUT can be used.
The state of the digital inputs can be viewed using the Mint WorkBench Spy window's
Axis tab. See the Mint help file for details.
