Citect fx3U ethernet zero value ?

[ta2mix 0]

I finished my project with citect 2016. 4 x fx3u connected with Ethernet. It shows n / a when the Ethernet connection is disconnected, this is normal. but my trends sometimes show zero for 3 or 5 seconds. how do I prevent it. I couldn't find a solution.

@ta2mix Are Trend Pen in Process Analyst from Trend Tag or Variable Tag? Zero trend values are occur when disconnect or random? If they are from disconnected do you need to retain last value before disconnected?

Hi Wasan

I used process analyst and trend tag ( this is work from hdd archive) I made  two project with wincc and citect ( two pc server). when the problem, Wincc project stably and good work but citect process analyst 2 or 4 times a day at different times recording zero value.

@ta2mix Maybe connection lost for a few second. I think there are Citect.ini parameter that hold last value when communication lost. Please share us your trend tag setting for check them.

@ta2mix Maybe you should adjust parameter [Trend]GapFillTime by follow these instructions

1. Open Citect Studio and go to Projects Tab select drop down at Setup Wizard then select Setup Editor.

2. Go to on the right then select Parameter Categories.

3. Select Trend Parameters.

4. Select [Trend]GapFillTime

5. Adjust Value to 30000 (or value orf time that for fill gap with values) then select Add Button.

6. Go to File then Save.

7. Run your project again.
