Hi,
Please check whether controller has the "Battery", if you restart the controller (power OFF and power ON) with "Battery" connected, variables will retains the same values and it wont go to zero. Otherwise you can set saftey value like Hold last vaue or Substitute value.
Hi Lukas
Sorry first of all i want to say sorry. i didn't notice you askiing question for 800F i told you about 800xA and my other friend did the same.
But Anyhow Please find the screen shot of the 800F Builder and check the inital value column. you can give the inital value and when system will restart then your varible will stay on these values
Please give your feedback problem solve or not.
Hi,
I have tested this using Freelance 2013 version with AC700F controller.
If you restart the AC700F controller when Battery is connected variables retains the same values, if you restart the AC700F controller when Battery is not connected your application will get deleted from controller. Please check the controller battery.
For eg:
Created "Variable_1"(Real data type) in FBD editor and changed value of Variable_1=55.5 in commissioning mode, restarted AC700f controller, now Variable_1=55.5
Created Counter variable "Variable_2" which will increase the value every second, restarted AC700f controller, now Variable_2 value will start increase from last value.
Please provide your comments...
Hi,
Please find attached my test project for your reference.
And one more option is, you can set the power fail time for AC700F controller, open parameter window of AC700F resource in P-tree, set the power fail time.
"Power fail time" option also will work when battery is connected with controller.
I hope this helps you...
Dear Lukas,
Now Freelance version 2013 is released, hence recommended to use released version instead of beta version. Note that controller firmware needs to be updated to released version, too. And before upgrade save and export your project in csv format.
After having released version 2013, make sure
1)fully charged battery is properly installed ?
2)Check on front LCD Display, against BATT there is triangular mark?
3)Configure BTL variable under controller diagnostic, If there is any battery low indication ? in commissioning mode you can check this variable status 1=Battery low.
4)Also you can configure some logic i=i+1 under system task res.ColdSt(Once) To check if your controller performs cold start after power on/off value get incremented. these you can check in current version also.
In summary if controller performs cold start, values not get resume from last value. it takes initial values. Incase no success recommended to get connected with local/regional support colleagues to find if anything special in your case.
Bytheway what is power off duration ? when you perform power off/on ?

Hi, thanks for your help. I think that my problem is here. In the picture named Time is Error time (local time) : DT#2013-01-01-00:00:00:527, and this time is different as time in the picture named Time2. How i can change the time in the picture named Time.
Hi,
How many controllers using in your network?
Always controller will be the Time Sync master in Freelance. Controller which has lowest resource ID that will be Time Sync master, pls check resource ID in IP configurtaion window in CBF.
Enable the Time Sync option from Configure window, close and open CBF/Digivis after enable time Sync.
To check which controller is Time Sync Server through controller interface, type controller IP address in IE. eg: http://172.16.1.10/
To change the controller Time, in commissioning mode open System time and change Actual time, check controller time through controller interface.

Can you please make it clear it is related to Freelance controller AC 700F or Controller AC 800M ?
