Hi
I use IoT2040 and figure out good work.
What I'd like to know is how to develop input/output module via node.js.
I could work OPCUA server and client in IoT2040 via node.js. So I also want to work I/O module via same language.
Which module(node.js) I use to control input/output pin?
Thank you.
It's great to hear you've had success with OPC UA on your IoT2040! To control input/output pins directly via Node.js, you'll primarily utilize the onoff Node.js module.
onoff provides a simple and effective way to interact with the GPIO pins on the IoT2040. Here's a quick overview:
npm install onoffYou can find examples and further guidance on accessing GPIO pins with Node.js specifically for the IoT2040 within the Siemens documentation and community forums. Search for "IoT2040 Node.js GPIO" on Siemens Support and Siemens Community.
Considering your OPC UA experience, you might also explore building a Node.js layer *on top* of onoff to expose I/O control via OPC UA, providing a unified interface.
