I've used the "offset" feature for this type of thing. On one of your objects, open up properties and go to the Extended tab. You can set up an addressing offset register that can be a PLC or screen device. The offset works just like indexing in the Mitsubishi PLCs. For example say you set up the offset on a momentary pushbutton with address M100. The offset address is D100. If D100 = 37, then touching the pushbutton operates M137 (i.e. M[100+37] ). Offset works for bits and data registers. What I've done is create a manual valve control popup, with an offset set up on all the devices on the screen. The offset device was GD100, which is a register on the HMI itself. Then on the screen that calls the popup, I created a multifunction button that opened the popup and set GD100 to what offset value I needed for the valve that the user touched. Note that this requires that my valve controls be set up consistently. For example, each valve has a range of 10bits that control manual/auto, on, off, etc. My popup uses bits M700-M709. If I want valve 1, I set GD100 to 0 (for M700-M709). If I want valve 2, I set GD100 to 10 (for M710-M719). If I want valve 3, I set GD100 to 20 (M720-M729). And so on and so forth.
