I wonder if storing the operator entry as a string would work, padded out to the left with zeros.
That way no digits are lost, and the value can be recovered at any point downstream.
Does the plc ever make any calculations with the value?
Storing them as strings and transferring that string to the PLC was one of the thoughts I had. I do some simple arithmetic in the PLC with the numbers to calculate the indicated volume for each meter, then return the value to WW
Steve Bailey is correct that the operators are transcribing a number, so I don't think incrementing counters would be helpful here.
I have RSLogix5000 v16.04.00(CPR 9).
