Getting Started

Before opening CODESYS, flash the board with the CODESYS runtime using the neXo Firmware Flasher — the runtime must already be running on the board.

1. Install the device description

1. Download CODESYS_Control_Pico2_W.devdesc.xml — [link da inserire].
2. In CODESYS: Tools → Device Repository → Install…
3. Select the downloaded .devdesc.xml file and confirm.

The device then appears in CODESYS Control devices as:

Name	CODESYS Control Pico2 W
Vendor	nexo S.r.l.
Device ID	167e 2008

2. Create a project and add the device

1. File → New Project… → Standard project.
2. As the device, pick CODESYS Control Pico2 W.
3. Under the device node, the Peripherals module (I/O, analog inputs, LED, temperature, WiFi parameters) is added automatically — see IO Mapping and WiFi Configuration.

3. Configure WiFi and connect

1. Set the WiFi SSID/password and IP settings — see WiFi Configuration — and download the application once (over USB) so the board joins your network.
2. In the device editor’s Communication Settings, scan for the device on the network and select it.
3. Login and download subsequent updates over WiFi.
