Hello everyone,
I’m trying to develop a module for Ignition 7.9, which would integrate an already existing Ignition-based solution.
The current problem is that I want to “handle” an existing Standard Tag Provider from this module: I thought I found something promising in the 8.0 Tag API Examples of the SDK Programmers’s Guide, like Read and Write Tags - Ignition SDK Programmer's Guide - Ignition Documentation, but anyway I was not able to adapt them for version 7.9, which is mandatory.
Afterward, I tried to use the simple-tag-provider example module (v. 7.9) as a starting point to achieve the same goal, but I came to the conclusion (I probably reinvented the wheel) that I can’t use a brand new Tag Provider instance to manipulate the existing provider. In my attempt, I used the same name to generate a Tag Provider from the module, hoping that somehow it would have been able to “detect” the other one in Ignition and “fallback” on it: when I opened the Designer, there was effectively a Tag Provider with the right name but without any tags; after I uninstalled the module and restarted the Designer, the original (Standard) Tag Provider reappeared correctly.
In the end, I’ve come across this thread Creating Standard and Remote (Not Managed) Tag Providers Using SDK, where @pturmel post seems to be the final answer to my problem (despite the different context).
So, even sounding like completely dumb questions, I have to ask:
- is it possible to achieve the handling of an existing Tag Provider from a module in Ignition 7.9? And in Ignition 8.0/8.1?
- in case it is indeed possible, can someone please provide a small example (or a link of where to find it)?
