Inputs, Outputs, and Modules is the hardware source of truth. This is where you can define what you will connect to each of the hardware pins and how it should be interpreted throughout the controller.
UI path
- Open Configuration.
- Select Connections.
- Expand Inputs, Outputs, and Modules.
- Add or edit the hardware module(s). You can use the “add multiple” toggle to add multiple modules without having to re-open the window each time.
- Set IDs, types, pins, addresses, channels, and bus settings.
- Click Apply I/O Changes (This will automatically reboot the controller and refresh the page).
| Hardware | What this section defines |
|---|
| Digital inputs | Buttons, switches, latches, beam breaks, and contact sensors |
| Analog inputs | Potentiometers, sliders, sensors, and variable-level sources |
| Digital outputs | Relays, solenoids, E-magnets, and trigger lines |
| Matrix keypads | Row/column keypad modules and key layout sources |
| RFID readers | Reader modules, bus settings, and reader IDs |
| Sound modules | Audio hardware, pins, and module IDs |
| Pixel outputs | Addressable LED data outputs and strip IDs |
| Expansion modules | I2C, SPI, relay boards, GPIO expanders, and similar modules |
