I have the same problem, I have put in the maximum 999 to Trend values on the trend pen. In Time Axis I have 36000 seconds (10 hours)

I only see trend curve of the last 16.65 minutes.

How can I set up this system to show the last 10 hours? realtime, I don't want to save anything on disc.

I use TIA V13, KTP900 Basic PN

Frank,

did you ever figure out on how to display 10 hour worth of data on your trend view? I'm looking for a solution to allow me to do this also

Thanks,

Hello poth_elec,

can you post a screenshot with the "trend view" control in the screen and its "Tima axis" properties?
I tried it with a TP700 comfort panel in TIA V13 SP1 and I don't have any problem with it.
I used a time interval of 36000 (s) and an increment of 3600 - to have 10 parts visible.

I have allso the same problem whit trend view. If there are many trend views I see trend curve of the last 2 minutes in each trend view. And if i use only one trend view then I see curve about 16 minutes. How can I get longer trend view ? 

I have tried to chance trend values (1-999),time interval(s),increment whit no change. 

Can I use "historical data" to save trend view to usb flashdrive ?

I use KTP400 basic PN whit TIA PORTAL v13.

can anyone confirm if it is only this time that is shown?

Hello rdoliveira,

to fix this you need to know the following:

Under "Properties > Trend > Source Settings" you can change two Settings, that are important here:

• "Trend values" - of course you select the maximum of 999 trend samples
• "Source settings" - Aside from the source tag you select the update cycle for the trend. Set this value to x. x is calculated as below:

Example 1: trend length unknown, cycle time  = 1s
999 trend samples, x = cycle time  = 1s
trend length =999 * 1s = 999s = 16 minutes, 39 seconds

Example 2: cycle time unknown, trend length = 1h
999 trend samples, trend length = 1h =3600s
x = 3600s * 1 trend sample/ 999 trend samples = 3,6s

Example 3: cycle time unknown, trend length = 10h
999 trend samples, trend length = 10h =36000s
x = 36000s * 1 trend sample/ 999 trend samples =~ 36s

Example 4: cycle time unknown, trend length = 24h
999 trend samples, trend length = 24h =86400s
x = 386400s * 1 trend sample/ 999 trend samples =~ 86,5s

 that's right, I was testing it right now.

 I have a doubt my friend... So is there a maximum Trend length, I mean is there a limit... as the calculation goes, longer the cycle time, longer the trend length... Another doubt is on the properties, there is time axis... on the range there is time interval, which i understand is for the graph time axis interval, but on label there is increment... Can someone please explain what that is ???
