Hi all, new to PLCs and to Wonderware, but I'm learning. I have a question about displaying a historical value, not as a trend, just a value. I have implemented a rain gauge into the Wonderware HMI, but now I want to show a rain count for the past 24hrs.
The rain gauge simply counts up by 1 whenever a small bucket is filled. So, the input to the PLC (Unity Pro xl, Schneider Quantum) is just +1. I have converted that to mm for the HMI display, which works.
How can I also display a count for the previous 24 hrs? I know I could display a trend, but just want to display the number.
Make any sense?
Thanks, looking forward to being a part of the forum.
