I/O Settings (Edge)

The Turbine range of stations have configurable I/O's, i.e. you can choose if an I/O should be used as an Input or as an Output. By default all I/O's are set as Inputs.

• When configured to be an Input, the input actions are configured from Direct Access Key Settings.
• When configured to be an Output, the output operation is configured from the Edge Controller in an Edge system.

By default an input is triggered by a closing contact (referred to as "NO - Normally Open"). The input can be configured as "Input NC" (NC - Normally Closed) instead. (Requires firmware 8.1.3.0 or later).

Enable Advanced Configuration mode, and select Edge Configuration > I/O from the menu

For each of the six I/O pins the options are:

• Input (default)
• Input NC
• Output

Use Inputs As Key Matrix

If there is a need for more than the 6 inputs available, it is possible to use the Use Inputs As Key Matrix and combine inputs as in a diode matrix, and in this way create more DAKs. By for example using 3 inputs it is possible to get 7 DAKs.

This is enabled in Advanced Configuration Mode and IO Settings:

Enable IO Matrix

The different options are:

• 2 Inputs (input 1-2, DAK 1-3)

Input 2	Input 1	DAK key triggered
0	1	DAK1
1	0	DAK2
1	1	DAK3
0	0	Last DAK released

• 3 Inputs (input 1-3, DAK 1-7):

The DAK actions are configured from Direct Access Key Settings.
