Hi,
I am trying interfacing Janitza UMG96S energy analyzer with Data logger. I am facing some issues regarding reading correct data from Modbus address. The device supports RS485 interface only and i am using RS485 to USB converter and MoDBUS poll software to view data on addresses mentioned in analyzer user manual.
The address starts from 200 and ends at 430 approx. The relevant data which i require is available on addresses 200 to 212, 270 to 281 and 416.
Now when i select address range 200 to 220 the modpoll gives correct value.. As soon as include the 270 to 281 addresses along with 200 to 215, the data which was being correctly displayed earlier becomes totally different.
Now if i only choose data range from 270 to 281 modpoll display correct data. This time again if i add 200 to 212 address in address range the data again gets disturb...
I am unable to figure out this problem. Please note i am reading the holding register and Data type U16. Device communication is correctly established...
Kindly share your thoughts on this...
Best Regards
