NTXS with NT2S screen register

[manowar]

Hello. I'm using NTXS v1.4 software together with NT2S-SF122B-EV2 DISPLAY. I'm having problem with screen register. I would like to do somekind of return to screen1 if no key is pressed. I have this application working with NT2-ST software. In NT2-ST the screen is avtomatically linked to register DM0. In NTXS v1.4: In PLC I have register DM0 for screen number. I have used the "Copy Tag to STR" in global task. But the problem is, that I can't change screen using NEXT or PREV keys on display. Displayed screen is connected directly to DM0 register. I can change screens ONLY using DM0 in PLC. In NT2-ST software this register was refreshed from NT2ST to PLC, but if I changed DM0 in PLC the screen changed. What can I do?
