S7 and HMI presence

Zoldex Posts: 9 Rating: (0)	Hello, I've noticed that some machines, from different vendors, have different behaviours with HMI loaded / not loaded on the various panels (speaking of OP12 and 840D). Someone requires (checks) that HMI is running to let the machine works, others seems don't care if I exit from HMI/MMC, reboot and go to windows mode and play solitaire. How could I implement this kind of check? I've looked thru some docs but I didn't find anything useful. I guess there should be some kind of "life bit" from MMC and looked in DB59 (UDT59) and DB19 (UDT19) without luck. Any help? Thanks in advance
