Watlow SpecView from Watlow - Manual (Page 12)

SpecView from Watlow  12  Watlow Addendum
Decimal Places
Specify zero (0) to display whole numbers for parameters such as process variable and set point. Specify
one (1) to display these parameters with tenths precision, two (2) to display hundredths and so on. With
Modbus TCP networks you must include the decimal setting in the address string. For a Modbus RTU
network if the decimal place setting and comma delimiter are omitted, SpecView will display whole
numbers. Valid settings range from zero (0) to four (4).
Register Address Offset
The register address offset is the sum of the First Instance Address for the specific EZ-ZONE product,
any applicable Instance Offsets and the Gateway Offset, if any. The tables below give the First Instance
Address and Instance Offset for each instrument and product. The Gateway Offset is set by the user
when the RUI Gateway or RM Access Module gateway is configured. The First Instance Address and
Instance Offsets depend on the controller’s data map setting.
Gateway Offset
Be careful not to set up instruments that attempt to read Modbus registers that are mapped over by the
configuration of the gateway.
