Analog Input Menu). If the value 360 is loaded into Assembly Definition Address 91, the process value sensed
by analog input 1 will also be stored in Modbus registers 250 and 251. Note that by default this parameter is
also stored in working registers 240 and 241 as well.
The table (See Appendix: Modbus Programmable Memory Blocks) identified as "Assembly Definition Ad-
dresses and Assembly Working Addresses" reflects the assemblies and their associated addresses.

Configurator Software
To enable a user to configure the PM control using a personal computer (PC), Watlow has provided free soft-
ware for your use. If you have not yet obtained a copy of this software insert the CD (Controller Support
Tools) into your CD drive and install the software. Alternatively, if you are viewing this document electroni-
cally and have a connection to the internet simply click on the link below and download the software from
the Watlow web site free of charge.

Once the software is installed double click on
the EZ-ZONE Configurator icon placed on
your desktop during the installation process.
If you cannot find the icon follow the steps be-
low to run the software:
1. Move your mouse to the "Start" button
2. Place the mouse over "All Programs"
3. Navigate to the "Watlow" folder and then
the subfolder "EZ-ZONE Configurator"
4. Click on EZ-ZONE Configurator to run.
The first screen that will appear is shown on
the right.If the PC is already physically con-
nected to the EZ-ZONE PM control click the
next button to go on-line.
Note:
When establishing communications from PC to the EZ-ZONE PM control an interface converter will be re-
quired. The Standard Bus network uses EIA-485 as the interface. Most PCs today would require a USB to
EIA-485 converter. However, some PCs may still be equipped with EIA-232 ports, therefore an EIA-232 to
EIA-485 converter would be required.
As can be seen in the above screen shot the software
provides the user with the option of downloading a
previously saved configuration as well as the ability to
create a configuration off-line to download later. The
screen shots that follow will take the user on-line.
After clicking the next button above it is necessary
to define the communications port that will be used
on the PC as shown below. Clicking on the drop down
will allow the user to select the appropriate commu-
nications port. This will be the port assigned to the
EIA-485 to USB converter when it was connected to
the PC. The "Advanced" button allows the user to de-
termine how many devices to look for on the network
(1 to 17).
