68 Electrical installation: input / output
Digital inputs - general purpose DIN4 - DIN9
Location: OPT1, pin 3 (CREF0), pin 4 (DIN7), 5 (DIN6), 6 (DIN5), 7 (DIN4), 11 (DIN9),
12 (DIN8), 13 (CREF1)
These general purpose digital inputs are buffered by a TLP280 opto-isolator, allowing
the input signals to be connected with either polarity. Inputs DIN4 and DIN5 share a
common reference, CREF1. Inputs DIN6 - DIN9 share a common reference, CREF0.
When the MicroFlex e150 is connected to Mint WorkBench, the digital inputs can be
configured using the Digital I/O tool. Alternatively, Mint keywords including
DRIVEENABLEINPUT, RESETINPUT, ERRORINPUT and STOPINPUT 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.
