Looking for an idea what I'm doing wrong here.
FactoryTalk View 9.0 and building a runtime for a v5.10 PV+1500.
My pens are drawing like I prefer while the trend screen is displayed, but if I close the trend window and re-open it, the data is not re-drawn the same way.
Not sure if it's a problem with my trend setup or with the data log.
Trend setup:
Automatic chart update
5sec refresh
100 records per pen buffer
(I've also tried On Change with a 5sec heartbeat and get the same result)
Data Log setup:
300000 max data points
Log Trigger - On Change. 2sec max update rate, 0% change percentage, 90sec Heartbeat
See attached screenshot:
The lower-right trend shows the trend as it displays when the screen is open.
The upper-left trend shows it as displayed after you close the trend and re-open it.
The red pen is a simple 0/1 binary value. In the lower right, it shows a nice square-wave showing how long the value is 1. In the upper trend, it looks like the data is filtered or condensed down with long slopes instead of nice sharp transitions.
