decoding ModbusRTU serial read result

[scott.clark]

So I am reading a group of bits as a word:

strValue1 = ModbusRTUCom1.Read("41281")
lblReadResult.Text = strValue1

The result displayed lblReadResult.Text is "-256"

So what is the binary value of the register "41281"?  It thought it was a signed integer, but I am not sure.

All integers that come back are interpreted as signed. The easiest way I find to see what bits represent what numbers is to use the Windows Calculator in Programmer View. I select the Dec setting, put in the number, then select Bin,

Doing that shows that -256 = 1111111100000000  , so bits 8-15 is on

So to clarify, the modbusRTU read returns one word(16 bits) for each register.  So -256 would represent 1111 1111 0000 0000

Yes, you are correct. I modified my response above because I just noticed I did the conversion incorrectly.
