Connecting via Modbus TCP (Ethernet)
With standard Ethernet cables connect the controller(s) and the Silver Series EM OIT to an Ethernet
switch or connect the controller directly to the OIT.
Determining or Setting the OIT’s IP Address
If you connect the OIT to an Ethernet network in order to download programs or communicate with
controllers via Ethernet, you must ensure the OIT has a unique IP address and you will need to know
that address in order to communicate from your PC with the OIT.
To read or set the OIT’s IP address:
• Connect a USB mouse to the OIT, if desired.
• Apply power to the OIT.
• Once the OIT is powered up, move the mouse to the lower right corner of the OIT screen.
• On the menu bar click the setting button (the one with the gear icon).
• Enter the password. (By default this is 111111.)
Silver Series EM OIT 4 Watlow Addendum
• The IP address is listed in the System settings window on the Network tab. (If Auto Get IP
Address is selected, the IP Address is not editable. If you want to configure the OIT for a fixed
address, select IP address get from below, and enter the IP address here.
• Click OK to close the System settings window on the OIT.
Hints for using the Virtual Keyboard to enter the OIT password and IP addresses:
• It can take a few seconds for the Systems settings dialog with the password field to appear.
• If you do not see the Virtual Keyboard it may be minimized; click the keyboard icon on the
menu bar.
• Make sure the cursor is in the Password or IP address field on the System Settings dialog.
• You can tell the password key strokes are being entered if you hear the key chirp from the OIT
and see stars (******) appearing in the password field.
• If you cannot see the Password field, arrange the Virtual Keyboard and System Settings
dialog then make sure the cursor is in the Password field.

Basics
The Silver Series EM OIT can communicate with Watlow controllers via Modbus TCP or Modbus RTU.
This section defines terms you will encounter and provides information about Modbus communications
that will help you create a user interface with the Silver Series EM OIT for equipment and machines that
include Watlow controllers.
About Gateways, Controllers and PLCs
The Silver Series EM OIT can communicate with a variety of devices. Because many of these devices
are Programmable Logic Controllers (PLCs), EZwarePlus refers to devices in many places generically
as “PLCs”. Don’t let this confuse you. When you are setting up the OIT to communicate with a Watlow
product, from the OIT’s point of view the controller is a PLC.
This addendum refers to configuring the Silver Series EM OIT to communicate with “controllers”, but
the instructions apply equally to limit controllers and gateways such as the EZ-ZONE® RUI Gateway.
Parameter Register Addresses
The Modbus RTU and Modbus TCP communications protocols assume that each device’s memory is
organized in blocks of like-data. Each data block contains either read-only data or read/write data and
either bit-size data or word-size (16-bit) data. For example, the Coils data block contains read/write bits
and the Input Register data block contains read-only words.
Within each of these data blocks there is a range of memory locations. The data blocks are often referred
to by the first digit of their address range. For example, the Holding Registers are often referred to as,
“the 4x registers”. The Modbus standard defines both a numbering scheme and an addressing scheme for
the memory locations in the data blocks. The table below illustrates this information for the four most
commonly discussed data blocks.
Name Number Access
Because the location numbering scheme includes the data block number, it is helpful to think of it as an
absolute address. The absolute address specifies the address completely or absolutely in that it says
which data block and which address contains a piece of data. Because the location addresses do not
include the data block number, it is helpful to think of them as relative addresses. They specify where to
look relative to the starting point of the data block.
Some software and device manufacturers document the use of their products in terms of the numbering
scheme while others use the addresses. In either case the manufacturer typically calls the numbers they
Data

Numbers
Addresses
Silver Series EM OIT 6 Watlow Addendum
supply “the addresses.” So to use any two products together you need to know whether or not you have
to convert the specified “address” in order to get the result you want.
EZwarePlus’s Modbus drivers call the data block, “Device type” and for “Address” expect the memory
location’s absolute address without the data block number. For example, to access a value in a holding
register with absolute address 401,905, for Device type you select the data block “4x” and enter “1905”
in the Address field. The following illustrates setting this address in EZwarePlus.
(072)
Watlow controllers use only the 4x registers. Therefore, you will set the Device type to 4x when
accessing any parameter in a Watlow controller. Watlow manuals specify relative addresses. Therefore,
you must add one (1) to an address found in a Watlow manual (other than this manual) before you enter
it in EZwarePlus.
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 EM OIT, you will add one (1)
to the relative address and enter “1905” in the Address field in EZwarePlus.
(073)
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 in the controller’s
Setup Page, Communications menu with the Data Map parameter. 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.
Silver Series EM OIT 7 Watlow Addendum
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.
(078)
Choosing a Communications Driver
When you create a project using EZwarePlus you select the drivers necessary to communicate with the
Watlow controllers and any other devices with which the Silver Series EM OIT must communicate. For
Watlow controllers, you select one of these drivers:
• Modbus RTU Master—used with Watlow controllers that support Modbus RTU and communicate
via RS-232 or RS-485.
• Modbus TCP/IP Master—used with Watlow controllers that support Modbus TCP and
communicate via Ethernet.
Using the Modbus RTU Master Driver to Communicate via 485
When you set up the Silver Series EM OIT to communicate via 485, you add a Modbus RTU Master
device to the device list in the System Parameter Settings. Only one driver is required for each COM
port on the OIT to which controllers are connected. This is true regardless of the number of controllers
that are connected to that 485 COM port. Think of the Modbus RTU Master device as a driver for the
COM port not as a driver for the controllers themselves. That is why you choose the Modbus RTU
Master driver rather than the Modbus RTU Slave driver. The controllers are slaves; the OIT’s COM port
is the master.
Using the Modbus RTU Master Driver to Communicate via 232
When you set up the OIT to communicate via a 232 COM port, you add a Modbus RTU Master device
to the device list in the System Parameter Settings. When using 232 on a COM port, only one controller
can be connected to that port.
Using the Modbus TCP/IP Master Driver to Communicate via Ethernet
When you set up the OIT to communicate with controllers via Ethernet, you add one Modbus TCP/IP
Master device to the device list in the System Parameter Settings dialog for each controller that has an
IP address with which you will communicate. For example, if the OIT must communicate with three EZ-
Silver Series EM OIT 8 Watlow Addendum
ZONE controllers via Ethernet, add three Modbus TCP/IP Master devices to the device list in the

Addressing Parameters in Multiple Controllers
Normally the Silver Series EM OIT assumes that any register address you enter when communicating
via Modbus RTU is associated with the controller at the network address you set in the PLC default
station no field in the Device Properties under the System Parameter Settings.
To read or write data from a register in another controller on a 485 network, enter the network address
and register address separated by the number sign or hash mark (#). For example “3#2501” accesses
register 2501 in the controller with the Modbus network address 3.
(074)
Address Offsets in Multi-Loop Controllers
In controllers with more than one loop of control, more than one limit etc., there is more than one
instance of each parameter for these duplicated functions. The manuals for controllers such as the EZZONE RM, list the Modbus address and an offset for these parameters. Add the offset to the address
once to get the address of the second instance of the parameter, add it twice to get the third instance and
so on.
For example, the address of the Heat Power for Loop 1 is listed in the EZ-ZONE RM manual as 2244
with an offset of 70. The following table lists the addresses of the Heat Power parameter for each of the
four possible loops in the controller. The table also reminds you to add one (1) to the relative addresses
from the controller manuals before entering the parameter address in EZwarePlus.
Loop Address + Offset(s)
Accessing Parameters via EZ-ZONE RUI Gateways and RM Access Modules
Multiple EZ-ZONE devices can communicate with the Silver Series EM OIT via one or more EZ-ZONE
RUI Gateways or EZ-ZONE RM Access modules. When ordered with either the Modbus TCP or
Modbus RTU communications option, an RUI Gateway or RM Access module allows a Silver Series
EM OIT to communicate with multiple EZ-ZONE controllers without purchasing communication
options in each controller.

gateway. The gateway presents itself as a single device on the Modbus network; the OIT does not
communicate with the controllers, only with the gateway. The gateway is configured by the user with an
address offset for each controller connected to it. That address offset is added to the parameter addresses
for the controller.
For example, consider three EZ-ZONE PM controllers connected to an RUI Gateway configured with an
offset of 0 for the first controller, 5000 for the second controller and 10,000 for the third controller. The
table below indicates the addresses that must be entered in EZwarePlus to access the set point value in
the three PM controllers.

Data Types
The Silver Series EM OIT’s Modbus drivers support a variety of data types. The Watlow manuals
specify the data type of each parameter. However the terminology is not precisely the same. The table
below correlates the data types indicated in the Watlow documentation with the data types you should
select when configuring a screen object in EZwarePlus.

Important Things to Know
Note: Make sure the Modbus Word Order is set to Word Low High in the controller.
That is the setting that works with the Silver Series EM OIT.
Note: Examples in this manual use the map 1 addresses. If the controller’s Data Map is
set to 2, the examples may not work.
Caution: When using a multi-state switch object to set an enumerated parameter in a
controller, each time the user clicks the switch, the setting selected by the switch
is sent to the controller. When it is desirable to go directly from one setting to
another without intermediate settings, use a set word object or an option list to
set the parameter instead.
