PLC to HMI, multiple tags with indirect addressing.

Dear all,

I'm aware that you cannot "multiplex" structs or UTDs. You cannot address faceplates indirectly either.

But is there any way around this? I just don't want to have to multiplex each tag by itself. I can make a solution in the PLC which would change the data targeted by the HMI tags, but I'd rather do it in the panel.
So, I want to be able to address an array/struct or similar, indirectly.

I use TIA v13 sp2 upd4. Comfort panel 1200 and a 1500 PLC.

I don't mind it being script heavy, as long as it doesn't slow down the communication or panel too much.

All ideas are welcome. Thanks!

 I realize that this post is several months old, but for anyone who comes across it looking for an answer, there are ways to do this in SP1. If you can get away with creating an array of UDTs in your PLC, you can multiplex a UDT on your HMI to different elements in that array. See here for an example.
