Watlow Addendum
EZ-ZONE Modbus Instruments
Watlow recommends using Standard Bus communications between SpecView and EZ-ZONE products
because there are many advantages including automatic detection. However, there are situations where it
may be preferable to use Modbus RTU or Modbus TCP. For these cases the following instruments are
offered. The tables below list the parameters supported by these instruments.
