X3: Digital inputs - general purpose DI0 & DI3
These general purpose digital inputs are buffered by an opto-isolator, allowing the
input signals 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.
