Jakeed86 (Customer) asked a question.
How can I display a lot of array tag values on C-More HMI?
I have history arrays in my PLC recording test values and I would like to be able to display/scroll through them on my HMI. Is this possible without assigning a numeric display to each tag?
How many is 'a lot?'
How many values to show in one view?
I have 4 arrays with different test values and a time stamp array I would like to be able to read. The arrays have 5000 columns, but if I could read through 1000 of each array that would do it.
I have some projects that do this. I need to know a bit more about your PLC/HMI.
I have a description in a text file. It is almost quitting time. I can do a bit more tomorrow, if you do not get more guidance this evening.
What PLC?
Sry, I should have asked this in the first response.
Use a buffer array on the screen as a display. Maybe 10 values or whatever you want on a single screen.
Manipulate that in the PLC as you see fit. Each time you press "back" do some math to change index on the arrays(ie, add 10 to index) being referenced and move them to the buffer. This will be scalable to any size array and require the least amount of work in the HMI programming. Working within the PLC is much easier than the HMI.
