Function Boards

Function boards are small plug-in circuits that use an I/O channel in it’s native I/O mode. The function board may use one or more signal lines (digital in, digital out, analog in). The web gateway has no way of knowing which function board is plugged in and the usually the matching widget need to be tailored to suit the function. For example, when a Temperature Probe function board is attached, a user will need to set the Scaling for that channel’s analog input to Temp F or Temp C. This will convert the normal raw value, 0 to 1023, in to a temperature that can be displayed.


On the Modules tab, find your web gateway and verify that the channel mode is set to “I/O” and connect function board to that channel. The default channel mode is “I/O” after a hard-reset.
