I have a program that will have 20 parameter files for 1 page, and have 5 pages with 20 each. What i'm trying to figure out is how can i enable a bit in my plc when a certain parameter file is enabled. I know i can create an internal tag in the FTView which i'm doing, but wasn't sure how i can write a tag to the PLC when one is being used.
I have FTVIew ME and not SE. If i had SE i would use something like the 'Touch' animation for my screen change the loads the parameter file.

This should work but you may have to test it.
In the parameter file set a referance like #20 to be a PLC tag you want to set. Then for the screens Startup Macro set #20 to the value you want in the expression.
 
JaxGTO has a solution similar to what I would suggest. But in my method, you wouldn't write to the PLC from the parameter file. Instead, you might have:

#20 = 1 ----- That would be in one parameter file
#20 = 2 ----- In the next

That is using the example of #20 he used above. Then so on with each parameter file getting a unique value for #20. The number is entirely up to you. But that number still needs to get into the PLC. That's where a macro would come in. Create one macro with #20 going to the PLC tag and have that macro execute when the display opens.

This is how I would do it as well.
 
I created a macro just now. If {#101} == 1 then enable {[PLC]Parameter_File.1}, if == 2 then .2 and so on. About to try it out and see what i get.
Thanks all.

Well that didn't work like i was wanting. I just want to enable a bit in the PLC if a certain parameter file is enabled. I have HMI internal tags so that if parameter file A is enabled, then InternalTagA = 1, if file B is enabled then TagB is = 2, and so on. I am eventually going to have 20 parameter files that could be enabled. Just wish there was an easier way with ME.
