Hello All,
Quick question regarding polling a Modbus device (NuFlo Scanner 2000 flow meter) with a AB CompactLogix and a Prosoft MVI69-MCM card.
I am getting data back from the device, however I am unable to make sense of it.
In the NuFlo user manual it tells me that all the Holding registers are Floating points (At least thats what I think FP means under data type). When I receive the data it is in 2 separate registers and the values are huge
Ex.
MCM.DATA.ReadData[24]= 16288
MCM.DATA.ReadData[25]= -6765
Do these 2 registers have to somehow be combined to get a value from them? If so, which command would I use in RS5000? I have tried using the COP command, and making the destination a real data tag.
Thanks in advance
Austin
