Hi. I use labview 8.6 + dsc module. 
I want to read tags  from a power analyzer on modbus rtu protocol. i have the register map of  the device. I configured ni opc server and tags needed. The problem is  that i don't know how to read the entire value from register. For  exemple, U12 is 217.45 Volts. My tag is configured to read a word  (16bit) register, but the value that i see with opc client is just 217. I  can't see decimals. If it was 21745, then it was an easy job to scale  that value (divide by 100). 
So, how can i see decimals ? Were should i look for ? 
 Thanks.
