Modbus logging

[dave.bolas@se.com]

Hi,

I am reading the active energy delivered from an ION7650 via Modus TCP. I can see the value correctly decoded in the object view, but when I look at the object log view, the Decoded Data, Data Type and Object Data are all showing '--' (The data type in the Object view is 4 byte floating point.)

Any suggestions as to what I am doing wrong?

Regards

Dave

Can you share a screenshot of the value in object tab and in the Object log tab? Also edit the object and send screen too.

Screenshots added. I'm on Teamviewer if you want to drive?

This is read telegram. Set the pool interval to 0. Modbus reading is set in modbus tab under device settings.

Go to objects, edit object 5/1/11 and 5/0/10 and set pool interval to 0

Done. Now its not logging at all.

Check Error log in the Modbus tab.

No errors. But despite the Modbus "Value send delta" being set to 0, it only seems to log when the raw (pre-scaled) value changes by 1. So I get logs at 173,000 then 174,000 etc

Even if delta is set to 0 new value is sent only when it differs from the previously sent value. It's possible that the value resolution for this register is 1.

Brilliant. Thanks.
