I am putting this in the General forum because it is really vague and sort of nebulous and could technically apply to other software besides Ignition, but that is what I am using.
I am a software engineer by trade and was put in charge of Ignition for a new plant we’ve built. I am not looking for specific answers to questions, but instead I am looking for direction on where I can read and learn about how to answer these questions. Any and all guidance is appreciated and I hope you can bear with me through what might be a painful explanation…
I have a device in a plant that I need to program/schedule using Ignition.
I have a mixer, ran by a motor, and the motor is driven by an Allen Bradley Powerflex 755.
I need to run the mixer on a schedule:
- If the mixer is set to ‘Auto’
- Run Forward/Reverse depending on the schedule
- Set a specific speed for the mixer
The scheduling is taken care of in Ignition, that was actually quite easy with a couple of emails to IA support. However, figuring out how to exactly control the motor/mixer has left me vexed.
I’ve read over the documentation and I am coming up short on everything.
I look in Ignition and I see a lot of tags for the motor/mixer. Tag examples:
My question is, how do I know what values to write to which tags? I mean, I can infer some of what I need to do based on tag names and some previously written software in Ignition. But if I want to run the mixer in forward how do I know that I am supposed to write ‘x, y, z’ to tags ‘a, b, c’.
Where would that be documented? I don’t see anything that even remotely resembles those tag names in any of the docs that I have access to. Is this something that I am just supposed to know as a controls/scada/etc person? Am I missing a a piece of the puzzle?
I have documentation on the Powerflex, the mixer/motor, and I have Ignition. Is there more documentation I should be looking at? Is there another piece of software I can use to look at the configuration of the tags and what the mean?
I hope this isn’t too incredibly convoluted and I know my lack of knowledge is showing but I am running out of resources.
