I am in the process of migrating a Quickpanel Jr screen that has a few dead pixels resulting in hard to read numbers. The current PLC is a old GE 90/30 utilizing the SNP communication protocol. I never used a GE as I am a Allen Bradley boy but it looks rather straightforward. I plan on using a G307K2 Red Lion HMI.
So I have created my screen in Crimson 3.0 and everything looks good but I have some questions on data tags, Double integers and decimal places.
For Example:
On the Quickpanel JR there is a variable called RLUI10 which is the the R0010 register on the GE 90/30. They have it set up for a DINT on the PLC and the HMI. Now the tricky question is they are using decimal points on both the display and user input of this register. It is shown as 00.000 (2 before DP, 3 after DP) with a entry limit of 0.010 to 10.000. In Crimson 3.0 I set the tag as .LONG and I used the scale to floating point option so I could set my limits correctly with the decimal point. I am assuming out of the PLC that number could be a 00010 to a 10000 (Based on the HMI data limits) and the HMI will use the data format to place the decimal point. Then if the operator enters a 1.25 the HMI will send a 01250 to the PLC. Please let me know if I am on the right course.
I am new to a GE 90/30 and Red Lion as I normally use C-More touchscreens.
