Exploring the Possibility of Getting Feedback from CMD/.bat Gateway on Ignition Automation

[Miguel_Cimildoro]

Hi, everyone

I am involved in a project where I need to determine if it is possible to get feedback by capturing the output of a CMD/.bat executed on the Gateway.

The idea is to disable a PCS through a script, and we need to know if the PCS has been enabled or disabled through a True or False value that can be displayed on the console.

How could we achieve this by associating that feedback to a boolean tag? I think this would be the perfect solution for our needs. Any suggestions or similar experience?

many regards

Pipe the .bat output to a file and then read the file?
myScript.bat > result.txt
I don't know how you would know when the task was finished though.

it works, but how can I pass it to the scada? by a tag? or is there another method that could be useful for what I am looking for?

You'll have to open the file in the Ignition gateway script, parse it and, if you want it in a tag then use system.tag.writeBlocking to write to that tag.

There may be some useful information in this thread:

Waiting in a Gateway Script

If you get an instance of GatewayContext (search the forums, I’m being deliberately vague here), you can get the shared ExecutionManager, which allows you to register a SelfSchedulingRunnable which has the same capability Kevin described built in. It would require some moderately advanced scripting know-how, but your scheduled task would also show up on Status → Execution.

Use Java's ProcessBuilder class to construct your external process call--it can expose the standard I/O streams for your use. Do not use system.util.execute for anything other than fire-and-forget operations.

thanks again Phil, I have used just the method you indicated, and after a few hours I have found just what I wanted.
