All,
Thanks for reading this post and for any ideas and suggestions. As stated on one of my previous post, I am in the process of upgrading an existing HMI system. I am needing to change over from the normal tag configuration of (i.e. Start Motor = B3:1/2) over to a parameter list configuration of (i.e. Start Motor = {2} and {2} = ::[Presses]ProgramROGRAM_1.B3[1].2)
In the correct configuration, it is a 1 to 1 PLC to HMI ratio. But I am going over to a 1 PLC controlling 23 HMIs. All HMI will have the same screens so this is why I am using the parameter list functionality so I can just create one Studio program and have just one runtime file.
Problem I am starting to see (and read) about is that there a 500 parameter limit when using parameter list. And the old HMI tags have a count of about 780.
I can trim some tags down but I will still be over the 500 count. Any suggestions how I can get around this and/or do this another way to accommodate these tags?
Thanks for all the help!!
