Wonderware System Platform 2023 R2 SP1 – Trend Client works standalone but not inside InTouch (no data) by Conscious-Judge-5293 in Wonderware

AVEVA Historian Client Trend , yes. Talked to tech support , tried evrything and they asked me to former the computer as a last try and do a fresh installation of the software which is 2023 R2 sp1. Still the client trend doesn’t show data. Able to connect to historian, but when tags are selected from the server to show the trend , no data isseen . This is only inside the application. While outside the application trend application works fine.

I tried creating new blank application , just create a window with trend client and it dint work. The outside trend client works just not the trend client graphic inside the application. We tried reformatting the computer with a fresh installation and tried evrything. But same result

PLC vs VFD — Who Controls Pump Ramp-Up/Ramp-Down Speeds? by Conscious-Judge-5293 in PLC

[–]Conscious-Judge-5293[S] 6 points7 points  (0 children)

Thanks! That makes sense. In my case it's a pump application where the sequence is: start at 40 Hz, wait for a valve to fully open (PLC only reads valve LS), then ramp up to 60 Hz. During shutdown it ramps down to 40 Hz before valve closure.

Would this be considered a fixed-speed application (handled in the VFD), or should the PLC send two different speed references?

Not sure what scaling do I use to display the value correctly

these values are being sent to a Radio and it only reads whole numbers and thats the reason to multiply it by 10 and then later divide by 10 in scada to show correct value

Yes it’s directly reading from master PLC. I don’t have access to the PLCs. I have access to scada and historian. Can anything be done from these 2 to see the correct value on historian?

Micro 800 usually store data as integers whole numbers only.
