Aret Posts: 2348 Rating: (264)	Well, if i understood correctly you have following situation - you need to define current status of devices on a request. In this case you should use SFC51, which allows to monitor status of modules/slaves/H-system status etc., and call this SFC on some regular basis. SSL-ID for SFC51 would be different according to your requirements - if you can specify what exactly are you trying to monitor constantly perhaps i can help you with SSL-ID selection.

Roman.Chernov Posts: 11 Rating: (0)	Aret, you see my point. Current status of devices on a request it's good. For it we use SFC51 and a system status list. When a system status list is updating? On a request or on an hardware interrupt?

Aret Posts: 2348 Rating: (264)	Let's say it's updated constantly. I.e. it has actual information on every moment you can call SFC51. I'm not sure, but my guess is it would be updated on interrupt in the middle of the cycle, but tests needed to make it sure.
