Historic Trend is not shown #561

First of all, very nice project!

I have set up a system with several SiemensS7_PLCs with an Live Line-Chart and a Historic Line-Chart. For Historic Linechart I use the same variable like the live chart. The variables are "Registration Enabled".

Somehow the historic trend is not working and not showing any values. What I get is following Warning: grafik

When I set everything up with only one connection, I get the same warning. I can´t find the Problem. What am I doing wrong? Thx sodaGin

This happens when the polling interval is shorter than the time it takes the server to read and handle the tag values from the PLC. How many PLC and Tags are you try to connect? HW? OS?

It is similar for me - no data on historical charts.

Data collection configured correctly. Any ideas?

Hardware: Siemens S7-1200 1214DC/DC/DC FW 4.2
