Thanks. I think that's exactly what I need.

Support Questions / AHMI using Rasberry Pi local IO?
« on: September 01, 2019, 05:14:44 PM »
Is it possible to address the local IO of a rasberry PI?

Here is an article that I think is very interesting and might just fit what you want to do:
https://www.dreamincode.net/forums/topic/395260-idustrial-process-regulation-using-a-vbnet-pid-controller/
I haven't tried to use it yet but it's on my list. I did write a 'pi' control in 6809 assembler back in the 80's but I got the equation with the constants from our company mathematician who modeled the process. I was just the implementor.
I don't normally like the HMI to do the work that I could easily do in the PLC, but there might be times that this would be appropriate.

I think what you put on the screen depends very much on your audience. I have one customer that has roaming technicians that assist the operators. They want 'big' flashing lights when the machine is not running. Another has managers that look at numbers and love digital panel meters.
Personally, I like numbers and charts. Production rates might also benefit some. For those that use statistical process control the trending charts are what they use to optimize their processes. I also like a little color but I use it sparingly. I try to add just enough to give the screen a little flavor without being overwhelming.
When given total freedom of the design I almost always try to show as much P&ID as possible with pertinent data . I don't do all that much with graphics as I believe that should not be the focal point of the screen and sometimes it takes up valuable space. Also I'm not very good with graphics.

Set the property 'enable logging' to false.

I haven't approached them about that. They've had some bad experiences in the past with other integrators so I'm trying to not scare them off too soon
thank you for the suggestions.

Yes I would have done it exactly as you described. I'm working with someone else's plc program.
I don't have a choice in the matter either as the customer won't take their equipment down for a software change. I either have to make my end work with what's there or not incorporate that data into the final solution.
I just ran a histogram on the output in the plc and it's rock solid. the machine is idling right now so the value is not changing. My display however is changing from 2375 to 9. Perhaps there is something about how the driver handles reading a whole output word versus bits.
I'm reading the value into a digitalpanelmeter and also a meter. The results are the same.

I almost have it. I had to use just the module number '2' in this case... I am still having a problem where the value isn't stable. It flashes between the actual value in the plc and another number. Still chasing that down. Perhaps I just can't reliably read directly from this type output.

The output module can be addressed by 3 different SCPs depending rung logic. Each scaling module uses a different integer for the input value so the only thing common to them is the actual output. I'm thinking I just don't know how to address it properly in AHMI. I'm just trying to read the entire word from the output module.
I'm attaching a sample.

Is there a way to read an Allen Bradley output module value? I'm wanting to use output 2.0 and read the value directly into a digital panel meter. I can modify the plc program to make an integer but it's hard taking this equipment down to do so.

Haha! Yeah but did you see apple stock today 
My customer is currently using a brand name HMI and paying around $700. I was hoping it would be in that range. I obviously don't know the market

there is no hurry. It may be over their budget anyway if it's going to be around the 10" cost. I'm still planting seeds for a switch.
I'll just keep an eye out for the release and go from there.
thanks
