If your Emotron drive were actually using Modbus Register 40000 for your 61563 value, then by mapping a tag to 40000.0-10 (default controller register size is INT16 but you can change it to UINT16 if you prefer un-signed behavior). The result is that the Value of Tag1 is driven by just the 11 bits specified by the ".0-10" portion. If you were to write a value from the HMI back to this tag (assuming read/write) then the value written would be masked by the bits specified as well.
