Reset totalizer on flow meter using modbus w/ RS-232 com

[MET]

Hi.  My name is MIke and I am trying to use Lookout 5.1 .  I have everything set up and working with the exception of one thing.  I am receiving a signal via RS-232 from an Eastech Badger Flow meter.  It is coming in from (2) modbus register.  The tech at the factory gave me this:

 These are in single bytes using MODBUS FUNCTION 10 (WRITE MULTIPLE REGISTERS)
 You may check on the register address. I looked at the location at the map and it shows it
 to be 210 and 211.

Currentslaveid = example 01h
CurrentModFunc = 0Ah
Startaddrhi = 00h
Startaddrlo = D2h = register 210
regcounthi = 00h
regcountlo = 02h
bytecount = 04h
Data = 05h FAh AAh 55h
Crcc code lo byte = XXh
Crcc code hi byte = XXh

Hope that helps

I am not sure what to do with this information.  Any help would be greatly appreciated.

This is the write function on registers 210 and 211. It is the whole data frame sent by Modbus master to Modbus slave. Do you read data from Flow Meter or write data to it? I think it should be reading, but you need to check what's the signal on register 210 and 211. From the message, it looks like that he wants you to write data to register 210 and 211.

Anyway, to read or write a register, you just need to make the connection in Lookout. You don't need to care too detailedly. You only need to know which address to read, or which address and data to write.

I just now noticed your subject... If you want to reset the totalizer, you need to write data to Modbus slave. The information seems the register and the value to write. He told you to write register 210 and 211, and the value is 05 FA AA 55. In Lookout, you need to use the decimal.
