Silver Series OIT 2 Watlow Addendum
1
Chapter 1: Introduction
The Silver Series Operator Interface Terminals (OITs) are powerful human machine interfaces for
equipment and processes. EasyBuilder5000 is easy-to-use and flexible software for creating the
windows, buttons, displays, gauges and other screen items with which operators interact on the OIT. The
purpose of this addendum is to quickly get you up and running with the OIT and software when used
with Watlow controllers.
Chapter 2: Install and Wiring provides information needed to physically connect the Silver Series OIT
to power and Watlow products.
Chapter 2: Install and Wiring provides definitions and information necessary for using an OIT with
Watlow controllers and other devices. Familiarity with these concepts is assumed in the tutorials that
follow.
Chapter 4: Programming Tutorials walks you through the steps of getting Watlow controllers
communicating, creating user interfaces and using powerful user interface features such as trending, data
logging and recipes with Watlow controllers.

Chapter 2: Install and Wiring
Consult the Silver Series Installation and Operation Manual for detailed information on installing and
wiring the OITs. This chapter provides important additional information regarding power supplies and
connecting to Watlow controllers.
Supplying Power to the OIT
Electrical codes require that devices connect to power via isolation approved by a third-party authority
such as UL. The TS00-0070-0000 and TS00-0100-000 do not yet have UL approval. Therefore, the
required isolation must be provided by an external component such as a Class 2 power supply. Meeting
the applicable requirements is the responsibility of the installer.
Connecting Controllers to the OIT
The following sections provide the termination information required to connect Watlow controllers to
the serial and Ethernet communications ports on the Silver Series OITs.

Basics
The Silver Series OIT can communicate with Watlow controllers using either Modbus TCP or Modbus
RTU. This section defines terms you will encounter and provides information on Modbus
communications that will help you when creating a user interface with the Silver Series OIT for
equipment and machines that include Watlow controllers.
About Gateways, Controllers and PLCs
The Silver Series OIT can communicate with a variety of devices. Because many of the devices are
Programmable Logic Controllers (PLCs), EasyBuilder5000 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 OIT to communicate with “controllers”, but the
instructions apply equally to limit controllers and gateways such as the 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
Silver Series OIT 4 Watlow Addendum
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
Coils 0x Read/Write 1 bit 1 to 65,536 0 to 65,535
Discrete Inputs 1x Read-Only 1 bit 100,001 to 165,536 0 to 65,535
Input Registers 3x Read-Only Word 300,001 to 365,536 0 to 65,535
Holding Registers 4x Read/Write Word 400,001 to 465,536 0 to 65,535
Data

Memory Location
Numbers
(Absolute)
Memory Location
Addresses
(Relative)
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 he
supplies, “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.
EasyBuilder5000’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 EasyBuilder5000.
(072)
Watlow controllers use only the 4x registers. Therefore, you will set the Device type to 4x to access 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 one) before you enter it in
EasyBuilder5000.
For example, the EZ-ZONE PM Controller Communications 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.
Silver Series OIT 5 Watlow Addendum
(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 manual.
Choosing the Communications Drivers
When you create a project using EasyBuilder5000 you select the drivers necessary to communicate with
the Watlow controllers and any other devices with which the Silver Series 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.
When you set up the Silver Series 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 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.
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.
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 EZZONE controllers via Ethernet, add three Modbus TCP/IP Master devices to the device list in the
System Parameter Settings dialog each configured to communicate with one controller.
Addressing Parameters in Multiple Controllers
Normally the Silver Series OIT assumes that any register address you enter 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.
Silver Series OIT 6 Watlow Addendum
To read or write data from a register in another controller on the 485 network, enter the network address
and register address separated by the number sign (#). 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 manual for controllers such as the EZZONE RM, lists 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 EasyBuilder5000.
Loop Address + Offset(s)
1 2224 2224 + 1 2225
2 2224 + 70 2294 + 1 2295
3 2224 + 70 + 70 2364 + 1 2365
4 2224 + 70 + 70 + 70 2434 + 1 2435

Accessing Parameters via EZ-ZONE RUI Gateways and RM Access Modules
Multiple EZ-ZONE devices can communicate with the Silver Series 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
OIT to communicate with one or more EZ-ZONE controllers without purchasing the Modbus
communications option in each controller.
In such a system the Silver Series OIT is connected to and configured to communicate with the 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.
Silver Series OIT 7 Watlow Addendum
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 EasyBuilder5000 to access the set point value
in the three PM controllers.
PM Set Point Plus Gateway Offset
1 2172 2172 + 0 2172 + 1 2173
2 2172 2172 + 5000 7172 + 1 7173

Data Types
The Silver Series 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 manuals with the data types you should select when
configuring a screen object in EasyBuilder5000.
EZ-ZONE RM EZ-ZONE ST EZ-ZONE PM EasyBuilder5000
Int Unsigned uint 16-bit Unsigned
dint 32-bit Signed
Float IEEE Float float 32-bit Float
Important Things to Know
Note: Make sure the controller’s Modbus Word Order is set to Word Low High in the
controller. That is the setting that works with the Silver Series OIT.
Note: Examples in this manual use the map 1 addresses. Make sure the controller’s
Data Map is set to 1.
Caution: When you use 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.
