Silver Series OIT  7  Watlow Addendum
For example, the EZ-ZONE PM Integrated Controller Models User’s Manual lists the relative address
for Heat Power as 1904. To monitor the heat power with the Silver Series OIT, you will add one (1) to
the relative address and enter “1905” in the Address field in EasyBuilder5000.

In summary, when setting an address for a screen object to read or write from a Watlow controller:
• For the Device type select 4x.
• Set the Address to a value that is one greater than the relative Modbus address listed in the
Watlow controller manual.
Address Maps
Some EZ-ZONE products have user-selectable address maps. Select the desired map with the Data Map
parameter on the Setup Page’s Communications menu in the controller. The Data Map affects the
parameter addresses at which values are read and written. The Data Map setting applies to all the
parameters in the controller. Generally Map 2 provides access to more parameters.
For example, the EZ-ZONE PM Integrated Controller Models User’s Manual lists Map1 and Map 2
addresses for Process Value for Analog Inputs 1 and 2. If the Data Map parameter is set to Map 1 then
the Process Value for Analog Input 2 is read at address 441 (the listed address plus one), but if Data
Map is set to Map 2 then the Process Value for Analog Input 2 is read at address 451. The address for
the Process Value for Analog Input 1 is the same for Map 1 and Map 2.
