How to change the AC800F CPU internal date and time
There are two ways you can set Freelance controller time (1) via CBF commissioning mode (2) Diagnostic cable
Anyways for setting up controller time and synchronise time systemwide check or follow following points.
1 All your freelance system resource should be on 172.16.x.y/255.255.240.0 for default timesynchronisation
2 All stations CBF/DigiVis must be enabled for timesynchronisation - Timesynch can be enabled from configure tool. pls note while enabling timesynch cbf/digivis needs to be closed. so if user enables timesynch when cbf/digivis is open please close and open once.
3 Make sure correct timezone is configured. - In configuration mode in Ptree right click on CONF > header > window opens select timezone button. check for correct timezone and select check box for daylightsavings if applicable. if not set this > save configuration and download to controller.
4 Now if you have more than one controller on network then controller at lowest ip address becomes time master by default. or you can go to any controller webserver by typing it's IP address on web browser and check which controller is active timemaster. it shows resource name or controller name which ever controller is active timemaster.
5 Goto CBF in commissioning mode > Ptree > select controller/resource which ever is active timemaster > go to option in CBF menu >SEt system time. Now while setting time i.e entering actual time value. do it faster don't take much time, because if you enter time value and then take some time (1-2 min) to press OK controller sets time with lag of 1-2 min the time user takes to say ok after user press ok.
