I want to know how to use the 'values' to vue component's data

[ldj011210]

function valuesReady(anythingBad, values) {
if (anythingBad) { console.log("SOMETHING WENT WRONG READING VALUES!!!!"); }
console.log(values);
doneReading = true;
if (doneWriting) { process.exit(); }
}
Where does this values come from, and how can I apply it to vue's components data()

values is the object created and returned by nodeS7 with the variable values from the PLC.

To get this into vue, you'd probably want to build a vue + NodeJS project, where NodeJS is the web server for the project. There are lots of examples if you google "vue node.js server example" and at least one of these should show how an object that exists on the server can work the way you're asking.

I will leave the issue open in case anyone else wants to submit a PR with an example or wants to comment more, but we don't use vue.

Hi there! Just wanted to chime in here for anyone coming across this thread in the future.
As @plcpeople correctly pointed out, the values object lives strictly inside the Node.js environment (the backend).

The key concept to remember here is the separation between Server-side and Client-side.

• NodeS7 runs on the server (Node.js) to handle the physical connection to the PLC.
• Vue.js runs in the user’s browser (Frontend).

Because they run in two different environments, your Vue component cannot directly access the variables inside your Node.js script. You need a “bridge” to connect them.

To get those values into your Vue data(), your Node.js script needs to act as a web server (often using tools like Express). The most common pattern for PLCs is:

1. Node.js reads data from the PLC using nodeS7.
2. Node.js sends that data to the browser using Socket.io (for real-time updates) or a REST API.
3. Your Vue component listens for that data and updates its state.

If you are new to the backend world, I highly recommend searching for “Node.js Socket.io Vue tutorial” or asking an AI tool to scaffold a simple bridge for you—it’s actually quite straightforward once you see the code!

@ldj011210 Since this issue is from a while back, did you manage to get this working for your project? If you (or anyone else landing here) are still looking for a solution, let me know, and I’d be happy to share a small code snippet demonstrating how to bridge nodeS7 to a web frontend.
