Title: Unsigned 16bit Integer
Post by: stuartscott171 on April 21, 2015, 04:02:38 AM

I can read a Modbus register fine, but can not work out how to display as a unsigned number i.e 65535.

The Modbus driver only supports signed integers. I will look into the possibility of adding unsigned support.

Reading an unsigned works fine with the prefix, but writing anything above 32767 doesn't.
"Failed to write value. The aritmatic operation caused spill"

This should be fixed in the next version that will be posted tomorrow.

Version 3.98j is now available. Try that version to see if it fixes the problem.
