Hmi tags
Just wondering I am from an RSView32 world so I feel a little lost here. In RSView32 every tag is counted with the exception of the "internal tags" I use the internal tags to open Visibility things such as if Button A is pressed the make Visible button B.
I am trying to migrate my RSView32 project into Factorytalk ME and the graphics and operation look and work great. I have the processor TAG Online and offline files working.
Now comes the interesting part I need to make a file within the TAG Browser for my "internal tags" These tags will also be used inside a recipe screen, things that do not need to goto the PLC. So RSLinx Enterprise will not let me make a new file, I can only place this file under the HMI named file in this case: Tension_Control_HMI I place a file there called BITS, I then click on the right side window and add my "Bits" BIT12, BIT13 etc these are all memory type some will be retentive.
So far so good. So i proceed to use them with a button on my screen: Value beside the arrow it states BITS\BITS12 I then add = 1 to it to make it an expression. When I save it and re-open the button the program has added parenthesis around the instruction that in my mind says if pressed BIT12 = 1.
I then create a runtime file and run it on my computer and when it starts to run I get an error message : Problem writing value 1 to item BITS\BITS2=1
pressing it again the error is: problem writing value 0 to the item BITS\BITS = 1
So my question is if you use DATA SERVER TAGS from the PLC can you not also make internal tags ?? If I can i must have missed a step as I just spent 4 hours trying every which way and I am still not making any headway.
Any help would be appreciated as always.
