When the MicroFlex e100 is connected to Mint WorkBench, the digital input can be configured using the Digital I/O tool. Alternatively, Mint keywords including RESETINPUT, ERRORINPUT and STOPINPUT can be used in the command window. The state of the digital input can be viewed using the Mint WorkBench Spy window’s Axis tab. See the Mint help file for details.
