The EZ-ZONE® RM Scanner (RMS) is capable of
monitoring from 1 to 16 inputs. As is the case with
all of the RM family modules the RMS can be used
as a standalone device or it can be used as part of
a larger system of interconnected RM modules. The
RMS takes the pain out of solving your need for high
density monitoring requirements as either a standalone module or in applications that require distributed control.
It just got a whole lot easier to solve the thermal
requirements of your system. The RMS module is
provided in a space-saving, rail-mount package and
is highly scalable where you only pay for what you
need. For those applications that require the ability to configure/monitor the module over a network,
Modbus RTU communications is an option. Other
communications protocols are also available (e.g.,
EtherNet/IP, DeviceNet, Modbus TCP and Profibus
DP) when used in conjunction with an RMA module
or when using a Remote User Interface/ Gateway
(RUI/GTW).

The flexibility of the RMS’s software and hardware
allows for variation in configurations. Acquiring a
better understanding of its functionality and capabilities while at the same time planning out how the
controller can be used will deliver maximum effectiveness in your application.
It is useful to think of the scanner in three parts:
inputs, procedures and outputs. Information flows
from an input to a procedure to an output when the
scanner is properly configured. An RMS module can
carry out several procedures at the same time, e.g.,
monitoring inputs for several different alarm situations, monitoring and acting upon digital inputs, and
outputs can be configured to drive devices such as
heaters, audible alarms, lights. Each process needs
to be thought out carefully and the scanner’s inputs,
procedures and outputs set up properly.
To set up a function, it’s important to tell it what
source, or instance, to use. For example, if the scanner is equipped with digital inputs they can be used
to silence an individual alarm or all alarms. The
RMS module can be equipped with up to 12 digital
inputs, instance 1 - 6 and 7 - 12.
Note:
Alarms will reset automatically when the condition
that caused the alarm goes back to a non-alarm
state if the alarm latching prompt is set to nonlatching (Setup Page, Alarm Menu).
Keep in mind that a function is a user-programmed
internal process that does not execute any action
outside of the controller. To have any affect outside
of the controller, an output must be configured to respond to a function.

Inputs
The inputs provide the information that any given
programmed procedure can act upon. Simply stated,
this information may come from an operator pushing
a button or from a sensor monitoring the temperature of a part being heated or cooled.
Each analog input typically uses a thermocouple,
RTD or thermistor to read the process temperature.
It can also read volts, current or resistance, allowing
it to use various devices to read humidity, air pressure, operator inputs and others values. Each analog
input must be configured to match the device connected to that input (see: Analog Input Menu, Setup
Page).
Each digital input reads whether a device is active
or inactive. An RMS module equipped with digital
input/output hardware includes two sets of terminals
where each of which can be used as either an input
or an output. Each pair of terminals must be configured to function as either an input or an output with
the direction parameter (see: Digital Input/Output
Menu, Setup Page).
Outputs can perform various functions or actions in
response to information provided by a function, such
as removal of the control voltage to a contactor; driving a heater; turning a light on or off; unlocking a
door; or turning on an audible alarm.
Assign an output to a function in the Output
Menu or Digital Input/Output Menu. Then select
which instance of that function will drive the selected output. For example, in using an RMS module, an
output can be configured to respond to the output of
the PID algorithm from another RM module to drive
a heat er.
You can assign more than one output to respond
to a single instance of a function. For example, alarm
2 could be used to trigger a light connected to output
1 and a siren connected to digital output 5.
Actions
Based on a given input (Digital I/O, Event output,
Logic function, etc..) the Action function can cause
other functions to occur. To name a few, set alarms to
off, silencing alarms and restoring user memory.
Functions
Functions use input signals to calculate a value. A
function may be as simple as reading a digital input
to set a state to true or false, or reading a temperature to set an alarm state to on or off.
Due to the scalability and flexibility in the RM system a user has several options available in the way
that the hardware can be connected. Listed below
are a few examples.
RMS Connected to a Remote User Interface (RUI)
and a Personal Computer (PC)
In this configuration the RUI and PC are connected
to the RMS module via Watlow's Standard Bus where
both will be able to talk directly to the RMS module.

RMS Module Connected to a Programmable Logic
Controller (PLC) on a DIN Rail
steps below to switch the RMS to the Standard bus
protocol.
1. Disconnect all Modbus devices from the network
2. Push and hold the orange button on the face of
the module for approximately 6 seconds
3. When the LED display (above the orange button)
changes to P [p] momentarily release the orange
button and then push it again where [S] will appear (symbol for Standard Bus), release the orange button
4. Push the orange button again for approximately
3 seconds (LED display will become brighter) to
change the Standard Bus address if needed
RMS Module Connected to an Operator Interface
Terminal (OIT) through an RMA
In this configuration the RMS can be connected to
the OIT through the RMA running any of a number
of available protocols. The RMA and the OIT must
be using the same protocol while the communications
from RMA to the RMS module is accomplished over
the backplane using Watlow's Standard Bus protocol.
Available protocols in the RMA follow:
1. EtherNet/IP and or Modbus TCP
2. DeviceNet
3. Modbus RTU
4. Profibus DP

Notice that in the example above that there is an optional RUI connected to the RMS along with the OIT.
OITs' are not generally used to configure a control
but are used more for run-time information. As an alternative for configuration the RUI could be used to
configure and monitor in a remote location.
One advantage in using an RMA module when communicating on a network is that protocol switching
is not needed on the RMS module if using an RUI
or EZ-ZONE Configurator software. The protocol of
choice used with the RMA can run simultaneously
with the Standard Bus protocol.
RMS Connected to a Split Rail with OIT
In this configuration both the inter-module bus
(backplane communications) and Standard Bus are
connected between rails to allow for remote capabilities. It is recommended that the split rail connection
not exceed 100 feet. In this configuration the OIT can
communicate with all modules (maximum 16 modules any combination with one Access module).

The picture that follows represents one of several different RM modules. All of them will have four slots
on the face (slot A, B, D, and E) and one on the bottom (slot C) not shown. All of these slots are not always used on all modules. On the face of the module
there is a button (orange circle) under the zone address ([5]). When pushed and held it has the following
functions:
1. For any module, push and hold the orange button
for approximately 3 seconds to change the zone address. Valid addresses for Modbus and Standard
bus range from 1 -16 ([1] - [9], [a] is 10, [b] is 11, [C]
is 12, [d] is 13, [e] is 14, [f] is 15, and [h] is 16). The
RMA (Access) module is shipped at address [j] or
17 and is the only module that can have its address
set above 16.
2. When a module is equipped with the Modbus protocol (RMxxxxxxxxxx1xx) pushing and holding the
orange button for approximately 6 seconds will
cause the LED display to return [P] for protocol.
Releasing the button and then pushing it again
(within 6 seconds) the display will toggle between
[N] (Modbus) and [S] (Standard Bus).
Consider taking the following steps to quickly commission your control:
• Wire and connect the power source to the control
• Wire and connect input and output devices to the
control
• Power up the control and navigate to the Setup
Page to configure inputs, outputs, adjust set
points, alarms, etc...
The RMS controller has a page and menu structure
that is listed below along with a brief description of
its purpose. The menu structure can be easily seen
and navigated using EZ-ZONE Configurator soft-
ware or the Remote User Interface (RUI).
Note:
The menu navigation as described below applies
when the RMS is connected to the RUI which is optional equipment.
Setup Page
Using the RUI, push
and hold the up and
down keys (¿ ¯) for 6
seconds to enter. (See
the Setup Page for further information)
Operations Page
Using the RUI push and
hold the up and down
keys (¿ ¯) for 3 seconds
to enter. (See the Op-
erations Page for further
information)
Factory Page
Using the RUI push and
hold the Infinity and
the green Advance keys
(ˆ ‰) for 6 seconds to
enter. (See the Factory
Page for further infor-
mation)
A user would want to
setup their control prior
to operation. As an example, define the input
type, alarm sides (high
and or low) or set the
output function.
After setting up the
control to reflect your
equipment, the Operations Page would
be used to monitor or
change runtime settings.
As an example, the user
may want to see the current status (on or off) of
an event in the Action
Menu.
For the most part the
Factory Page has no
bearing on the control when running. A
user may want to enable password protection, view the control
part number or perhaps
create a custom Home
Page.
Home Page
When using the RUI,
the control is at the
Home Page when ini-
tially powered up where
it will display the value
of Analog Input 1 in the
upper display and the
value of Analog Input 2
in the lower display.
Pushing the green Advance Key ‰ will cause
the display to show the
value of Analog Input 1
in the upper display and
Analog Input 2 in the
lower display. With each
successive push of the
green advance key the
display will sequentially
show the value of all

The Home Page is visible only when using
the RUI.
remaining analog inputs
in the upper display and
the lower display will
show the corresponding LED display. (e.g.,
[AIN3] for input 3)
The default RMS loop configuration out of the box is
shown below:
• All Analog Input functions are set to thermocouple, type J (to change go to the Setup Page, Analog Input Menu)
• All Process Value functions are set to off (to
change go to the Setup Page, Process Value
Menu)
• All outputs are set to off (to change go to the Setup Page, Output Menu)
Once the scanner has been wired and setup, power
up the control. If using an RUI the upper display will
show the value of Analog Input 1 and the lower display will show the value of Analog Input 2.

The picture on the right shows the Modular Backplane
Connector, both front and rear view. The rear view
is bringing in to focus a metal clip. If the DIN rail is
grounded the Modular Backplane Connector and the
module connected to it will be also (recommended).
Installing the Modular Backplane Connector
Step 1
Hook backplane assembly to upper edge of DIN rail,
(see rear view above, backplane hook detail that
mates with upper rail edge is circled)
Step 2
Next, rotate back plane assembly downward to en
gage the lower edge of the rail. (Note: Din Rail clip ping distance ranges from 1.366 -1.389 inches. The
back plane assembly will not latch onto the rail suc cessfully if the rail is out of dimension).
Step 3
For final positioning and locking, the red tab is to
be pushed upward to further engage the bottom
edge of the rail with an over center snap action
latch. (The red locking tab protrudes from the bot tom side of the back plane assembly).
Installing Multiple Modular Backplane Connectors
Multiple modules are easily aligned and latched together. Each module includes matched mating geometry that facilitates accurate and consistent interconnections. The recommended method of multi-module
attachment is to first attach individual modules to
the rail separately and second to laterally slide the
modules together until they touch. (Refer to steps 1&2
above). When the multi-module system is attached and
laterally positioned to the desired placement the locking tab should be engaged to secure the control system
to the rail, (Refer to step 3 above).
Module Installation
In the picture to the right notice that the arrow is
pointing at the top lip of the module (on side). When installing the module simply slide this lip over the top of
the Modular Backplane Connector and then push down
on the rear of the module where it will seat on the two
posts just above the green connector.
To remove a module from the
Modular Backplane Connector
find the red tab protruding from
the bottom of the module and pull
back on it as shown to the right.
While pulling back on the red tab
the two mounting posts will release the module where the module can then be lifted up and out
of the Modular Backplane Connector.
Removal of the Modular Backplane Connector
A module can be removed from
the Modular Backplane Connector
by inserting a screw driver into
the red locking tab just behind
the green connector and applying
downward pressure on the tab by
lifting the screwdriver upwards.
When released, the tab will move
downward and the connector can
then be lifted up off of the DIN
rail.

The RMS module can be installed as a stand-alone
scanner or can be interconnected on the DIN rail as
shown below with other RM family modules. When
modules are connected together as shown, power and
communications are shared between modules over
the modular backplane interconnection. Therefore,
bringing the necessary power and communications
wiring to any one connector in slot C is sufficient.
The modular backplane interconnect comes standard
with every module ordered and is generic in nature,
meaning any RM modules shown below on the DIN
Modular backplane interconnect
rail can use it.
Notice in the split rail system diagram that a
single power supply is being used across both DIN
rails. One notable consideration when designing the
hardware layout would be the available power supplied and the loading affect of all of the modules
used. Watlow provides three options for power supplies listed below:
With regards to the modular loading affect, maximum power for each RM module is listed below:
1. RMCxxxxxxxxxxxx @ 7 watts / 14VA
2. RMEx-xxxx-xxxx @ 7 watts / 14VA
3. RMAx-xxxx-xxxx @ 4 watts / 9VA
4. RMLx-xxxx-xxxx @ 7 watts / 14VA
5. RMSx-xxxx-xxxx @ 7 watts / 14VA
6. RMHx-xxxx-xxxx @ 7 watts / 14VA
So, in the split rail system diagram, the maximum
current draw on the supply would be 38 Watts.
- 2 RMC modules consumes 14W
- 1 RMS module consumes 7W
- 1 RME modules consumes 7W
- 1 RMA module consumes 4W
- 1 Remote User Interface consumes 6W
With this power requirement (38 watts) the second or
third power supply could be used.
Another hardware configuration scenario that could
present itself (graphic not shown) would be a configuration that requires more than one supply. Lets
make some assumptions pertaining to the split rail
system diagram shown below. The power supply
used is the 91W supply. The top DIN rail now has
the following modules:
- 2 RMC modules consumes 14W
- 1 RMA consumes 4W
- 11 RME modules consumes 77W
- 2 RMS modules consumes 14W
As can now be seen, the total power requirement
exceeds 91W. In this case, another power supply
would be required. To incorporate another supply in
this system simply disconnect pins 99 and 98 on the
remote DIN rail and connect another appropriately
sized power supply for the remote modules to those
same pins.
When using a split rail configuration ensure that
the interconnections for the Inter-module Bus and
Standard Bus do not exceed 200 feet. Standard Bus
and the Inter-module Buses are different protocols
and both are required for split rail configurations.
Without having both connected communications between modules would not be possible.

To better understand the menu pages that follow
review the naming conventions used. When encountered throughout this document, the word "default"
implies as shipped from the factory. Each page (Operations, Setup and Factory) and their associated
menus have identical headers defined below:

Note:
The RUI is optional equipment.
Range
Within this column notice that on occasion there will
be numbers found within parenthesis. This number
represents the enumerated value for that particular
selection. Range selections can be made simply by
writing the enumerated value of choice using any of
the available communications protocols. As an example, turn to the Setup Page and look at the Analog
Input [`Ai] menu and then the Sensor Type [Sen]
prompt. To turn the sensor off simply write the value
of 62 (off) to Modbus register 388 and send that value
to the control.
Communication Protocols and Software Tools
All RM modules come with Watlow's Standard
Bus protocol. This protocol is used primarily for
inter-module communications but is also used with
SpecView by Watlow, LabVIEW and EZ-ZONE Configurator software (free download from Watlow's web
site (http://www.watlow.com). Along with Standard
Bus, the RMS module can also be ordered with Modbus RTU (only one protocol can be active at any given
time). The RMA (Access) module has options for several different protocols listed below:
- Modbus RTU 232/485
- EtherNet/IP, Modbus TCP
- DeviceNet
- Profibus DP
Modbus RTU Protocol
All Modbus registers are 16-bits and as displayed
in this manual are relative addresses (actual). Some
legacy software packages limit available Modbus registers to 40001 to 49999 (5 digits). Many applications
today require access to all available Modbus registers
which range from 400001 to 465535 (6 digits). Watlow EZ-ZONE controllers support 6 digit Modbus registers. For parameters listed as f loat notice that only
one (low order) of the two registers is listed, this is
true throughout this document. By default the low order word contains the two low bytes of the 32-bit parameter. As an example, look in the Operations Page
for the Process Value. Find the column identified in
Page 36
the header as Modbus and notice that it lists register
380. Because this parameter is a float it is actually
represented by registers 381 (low order bytes) and
381 (high order bytes). Because the Modbus specification does not dictate which register should be high
or low order Watlow provides the user the ability to
swap this order (Setup Page, Com Menu) from the
default low/ high [lohi] to high/low [hilo].
It should also be noted that some of the cells in the
Modbus column contain wording pertaining to an offset. Several parameters in the control contain more
than one instance; such as, alarms (24), analog inputs (16), etc... The Modbus register shown always
represents instance one. Take for an example the
Alarm Silencing parameter found in the Setup Page
under the Alarm menu. Instance one is shown as address 2670 and +60 is identified as the offset to the
next instance. If there was a desire to read or write
to the same member instance 3, simply add 120 to
2670 to find its address; in this case, the instance 3
address for Alarm Silencing is 2790.
To learn more about the Modbus protocol point
your browser to http://www.modbus.org.
Note:
There are two columns shown in the menus that
follow for communications protocols identified as
CIP (Common Industrial Protocol) and Profibus.
These columns will be useful if this control is used
in conjunction with the RMA module or the EZZONE Remote User Interface/Gateway (RUI/GTW)
where those protocols can be selected as optional
hardware. For this module (RMS), as a secondary
protocol beyond Standard Bus, Modbus RTU can be
ordered as optional hardware.
To learn more about the RUI/GTW point your
browser to the link below and search for keyword
EZ-ZONE.
To navigate to the Operations Page using the RUI, follow the steps below:
1. From the Home Page, press both the Up ¿ and

Saving and Restoring User Settings
Time
Recording setup and operations parameter settings
for future reference is very important. If you unintentionally change these, you will need to program the
correct settings back into the controller to return the
equipment to operational condition.
After you program the controller and verify prop-
er operation, use User Save Set [USr;S] (Setup Page,
Global Menu) to save the settings into either of two
files in a special section of memory. If the settings
in the controller are altered and you want to return
the controller to the saved values, use User Restore
Set [USr;r] (Setup Page, Global Menu) to recall one
of the saved settings. A digital input or the Function
Key can also be configured to restore parameters.
Note:
Starting with firmware release 6, there is only one
user set.
Note:
Only perform the above procedure when you are
sure that all the correct settings are programmed
into the controller. Saving the settings overwrites
any previously saved collection of settings.
Be sure to document all the controller settings.
Note:
When restoring factory defaults, I/O assemblies for
Modbus, DeviceNet, Profibus and Ethernet along
with the zone address will be overwritten when restoring factory defaults.
Inputs
Calibration Offset
Calibration offset allows a device to compensate for
an inaccurate sensor, lead resistance or other factors
that affect the input value. A positive offset increases
the input value, and a negative offset decreases the
input value.
The input offset value can be viewed or changed
with Calibration Offset [`i;CA] (Operations Page,
Analog Input Menu).
Negative Calibration Offset will
Temperature Reading
from Sensor
compensate for the difference
between the Sensor Reading and
the Actual Temperature
Calibration
Before performing any calibration procedure, verify
that the displayed readings are not within published
specifications by inputting a known value from a precision source to the analog input. Next, subtract the
displayed value with the known value and compare
this difference to the published accuracy range specification for that type of input.
Use of the Calibration Offset [`i;CA] parameter
found in the Operations Page [oPEr] , Analog Input
Menu [``Ai] shifts the readings across the entire
displayed range by the offset value. Use this parameter to compensate for sensor error or sensor placement error. Typically this value is set to zero.
Equipment required while performing calibration: Obtain a precision source for millivolts, volts,
milliamperes or resistance depending on the sensor
type to be calibrated. Use copper wire only to connect
the precision source to the controller’s input. Keep
leads between the precision source and controller as
short as possible to minimize error. In addition, a
precision volt/ohm meter capable of reading values to
4 decimal places or better is recommended. Prior to
calibration, connect this volt/ohm meter to the precision source to verify accuracy.
Actual input values do NOT have to be exactly the
recommended values, but it IS critical that the actual
value of the signal connected to the controller be accurately known to at least four digits.
Calibration of Analog Inputs:
To calibrate an analog input, you will need to provide
a source of two electrical signals or resistance values
near the extremes of the range that the application is
likely to utilize. See recommended values below:
Sensor TypeLow SourceHigh Source

Sensor Selection
You need to configure the controller to match the input device, which is normally a thermocouple, RTD or
process transmitter.
Select the sensor type with Sensor Type [`Sen]
(Setup Page, Analog Input Menu).
Scale High and Scale Low
When an analog input is selected as process voltage
or process current input, you must choose the value
of voltage or current to be the low and high ends. For
example, when using a 4 to 20 mA input, the scale
low value would be 4.00 mA and the scale high value
would be 20.00 mA. Commonly used scale ranges are:
0 to 20 mA, 4 to 20 mA, 0 to 5V, 1 to 5V and 0 to 10V.
You can create a scale range representing other
units for special applications. You can reverse scales
from high values to low values for analog input signals that have a reversed action. For example, if 50
psi causes a 4 mA signal and 10 psi causes a 20 mA
signal.
Scale low and high low values do not have to match
the bounds of the measurement range. These along

Temperature
Temperature
Range High and Range Low
With a process input, you must choose a value to represent the low and high ends of the current or voltage
range. Choosing these values allows the controller’s
display to be scaled into the actual working units of
measurement. For example, the analog input from a
humidity transmitter could represent 0 to 100 percent relative humidity as a process signal of 4 to 20
mA. Low scale would be set to 0 to represent 4 mA
and high scale set to 100 to represent 20 mA. The indication on the display would then represent percent
humidity and range from 0 to 100 percent with an
input of 4 to 20 mA.
Select the low and high values with Range Low
[`r;Lo] and Range High [`r;hi] (Setup Page, Analog
Input Menu).
Linearization
Configure alarm outputs in the Setup Page before
setting alarm set points.
Alarms do not have to be assigned to an output.
Alarms can be monitored and controlled through the
front panel or by using software.
Process Alarms
A process alarm uses one or two absolute set points
to define an alarm condition.
Select the alarm type with Type [`A;ty] (Setup
Page, Alarm Menu).
Alarm Set Points
The alarm high set point defines the process value
or temperature that will trigger a high side alarm.
The alarm low set point defines the temperature that
will trigger a low side alarm. View or change alarm
set points with Low Set Point [`A;Lo] and High Set
Point [`A;hi] (Operations Page, Alarm Menu).
The linearization function allows a user to re-linearize a value read from an analog input. There are 10
data points used to compensate for differences between the sensor value read (input point) and the desired value (output point). Multiple data points enable
compensation for non-linear differences between the
sensor readings and target process values over the
thermal or process system operating range. Sensor
reading differences can be caused by sensor placement, tolerances, an inaccurate sensor or lead resistance.
The user specifies the unit of measurement and
then each data point by entering an input point value
and a corresponding output point value. Each data
point must be incrementally higher than the previous
point. The linerization function will interpolate data
points linearly in between specified data points.

Alarm Hysteresis
An alarm state is triggered when the process value
reaches the alarm high or alarm low set point. Alarm
hysteresis defines how far the process must return
into the normal operating range before the alarm can
be cleared.
Alarm hysteresis is a zone inside each alarm set
point. This zone is defined by adding the hysteresis

Using Lockout to Hide Pages and Menus
If unintentional changes to parameter settings might
raise safety concerns or lead to downtime, your can
use the lockout feature to make them more secure.
Each of the menus in the Factory Page and each
of the pages, except the Factory Page, has a security
level assigned to it. You can change the read and
write access to these menus and pages by using the
parameters in the Lockout Menu (Factory Page).
Lockout Menu
There are five parameters in the Lockout Menu (Factory Page):
• Lock Operations Page [LoC;o] sets the security
level for the Operations Page. (default: 2)
Note:
The Home and Setup Page lockout levels are
fixed and cannot be changed.
• Lock Profiling Page [LoC;P] sets the security level
for the Profiling Page. (default: 3)
• Password Security Enable [pas;e] will turn on or
off the Password security feature. (default: off)
• Read Lockout Security [rLoC] determines which
pages can be accessed. The user can access the se lected level and all lower levels. (default: 5)
• Set Lockout Security [SLoC] determines which pa-
rameters within accessible pages can be written to.
The user can write to the selected level and all
lower levels. (default: 5)
The table below represents the various levels of lockout for the Set Lockout Security prompt and the
Read Lockout Security prompt. The Set Lockout has
6 levels (0-5) of security where the Read Lockout has
5 (1-5). Therefore, level "0" applies to Set Lockout
only. "Y" equates to yes (can write/read) where "N"
equates to no (cannot write/read). The colored cells
simply differentiate one level from the next.

The following examples show how the Lockout Menu
parameters may be used in applications:
1. You can lock out access to the Operations Page
but allow an operator access to the Profile Menu,
by changing the default Profile Page and Operations Page security levels. Change Lock Operations Page [LoC;o] to 3 and Lock Profiling Page
[LoC;P] to 2. If Set Lockout Security [SLoC] is
set to 2 or higher and the Read Lockout Security
[rLoC] is set to 2, the Profiling Page and Home
Pages can be accessed, and all writable parameters can be written to. Pages with security levels
greater than 2 will be locked out (inaccessible).
2 If Set Lockout Security [SLoC] is set to 0 and
Read Lockout Security [rLoC] is set to 5, all
pages will be accessible, however, changes will
not be allowed on any pages or menus, with one
exception: Set Lockout Security [SLoC] can be
changed to a higher level.
3. The operator wants to read all the menus and not
allow any parameters to be changed.
In the Factory Page, Lockout Menu, set Read
Lockout Security [rLoC] to 5 and Set Lockout
Security [SLoC] to 0.
4. The operator wants to read and write to the
Home Page and Profiling Page, and lock all other
pages and menus.
In the Factory Page, Lockout Menu, set Read
Lockout Security [rLoC] to 2 and Set Lockout
Security [SLoC] to 2.
In the Factory Page, Lockout Menu, set Lock
Operations Page [LoC;O] to 3 and Lock Profiling
Page [LoC;P] to 2.
5. The operator wants to read the Operations
Page, Setup Page, Profiling Page, Diagnostics
Menu, Lock Menu, Calibration Menu and Custom Menus. The operator also wants to read and
write to the Home Page.
In the Factory Page, Lockout Menu, set Read
Lockout Security [rLoC] to 1 and Set Lockout
Security [SLoC] to 5.
In the Factory Page, Lockout Menu, set Lock
Operations Page [LoC;O] to 2 and Lock Profiling

Using Password Security
It is sometimes desirable to apply a higher level of
security to the control where a limited number of
menus are visible and not providing access to others
without a security password. Without the appropriate password those menus will remain inaccessible.
If Password Enabled [pas ;e] in the Factory Page
Watlow EZ-ZONE® RMS Module • 90 • Chapter 6 Features
under the [`loC] Menu is set to on, an overriding
Password Security will be in effect. When in effect,
the only Pages that a User without a password has
visibility to are defined in the Locked Access Level
[loC;L] prompt. On the other hand, a User with a
password would have visibility restricted by the Read
Lockout Security [rloC] . As an example, with Password Enabled and the Locked Access Level [loC;L]
set to 1 and [rloC] is set to 3, the available Pages
for a User without a password would be limited to
the Home and Factory Pages (locked level 1). If the
User password is entered all pages would be accessible with the exception of the Setup Page as defined
by level 3 access.
How to Enable Password Security
Go to the Factory Page by holding down the Infinity
ˆ key and the Advance
seconds. Once there, push the Down ¯ key one time
to get to the [`loC] menu. Again push the Advance
key until the Password Enabled [pas;e] prompt
is visible. Lastly, push either the up or down key to
turn it on. Once on, 4 new prompts will appear:
1. [ loC ; l] , Locked Access Level (1 to 5) correspond
ing to the lockout table above.
2. [roll] , Rolling Password will change the Cus tomer Code every time power is cycled.
3. [pas ;u] , User Password which is needed for a Us er to acquire access to the control.
4. [pas;a], Administrator Password which is need ed to acquire administrative access to the control.
The Administrator can either change the User and
or the Administrator password or leave them in the
default state. Once Password Security is enabled they
will no longer be visible to anyone other than the
Administrator. As can be seen in the formula that
follows either the User or Administrator will need to
know what those passwords are to acquire a higher
level of access to the control. Back out of this menu
by pushing the Infinity ˆ key. Once out of the menu,
the Password Security will be enabled.
How to Acquire Access to the Control
To acquire access to any inaccessible Pages or
Menus, go to the Factory Page and enter the [UloC]
menu. Once there follow the steps below:
Note:
If Password Security (Password Enabled [pas ;e]
is On) is enabled the two prompts mentioned below
in the first step will not be visible. If unknown,
call the individual or company that originally set up the control.
1. Acquire either the User Password [pas;u] or the
Administrator Password [pas;a].
2. Push the Advance
[Cod e] prompt will be visible.
Note:

vance key one more time where the Password
[pass] prompt will be displayed. Proceed to
either step 7a or 8a. Pushing the Up ¿ or Down
¯ arrow keys enter either the User or Adminis trator Password. Once entered, push and hold
the Infinity ˆ key for two seconds to return to
the Home Page.
b. If the Rolling Password [roll] was turned on
proceed on through steps 3 - 9.
3. Assuming the Code [Code] prompt (Public Key)
is still visible on the face of the control simply
push the Advance key
Password [pass] prompt. If not find your way
back to the Factory Page as described above.
4. Execute the calculation defined below (7b or 8b)
for either the User or Administrator.
5. Enter the result of the calculation in the upper
display play by using the Up ¿ and Down ¯ arrow
keys or use EZ-ZONE Confgurator Software.
6. Exit the Factory Page by pushing and holding the
Infinity ˆ key for two seconds.
Formulas used by the User and the Administrator to
calculate the Password follows:
Passwords equal:
7. User
a. If Rolling Password [roll] is Off, Password
[pass] equals User Password [pas ;u] .
b. If Rolling Password [roll] is On, Password
[pass] equals:

8. Administrator
a. If Rolling Password [roll] is Off, Password
[pass] equals User Password [pas;a].
b. If Rolling Password [roll] is On, Password
[pass] equals:

to proceed to the
Modbus - Using Programmable Memory
Blocks
When using the Modbus protocol, the RMS features a
block of addresses that can be configured by the user
to provide direct access to a list of 80 user configured
parameters. This allows the user easy access to this
customized list by reading from or writing to a contiguous block of registers.
To acquire a better understanding of the tables
found in the back of this manual (See Appendix:
(Modbus Programmable Memory Blocks) please read
through the text below which defines the column
headers used.
Assembly Definition Addresses
- Fixed addresses used to define the parameter
that will be stored in the "Working Addresses",
which may also be referred to as a pointer. The
value stored in these addresses will reflect (point
to) the Modbus address of a parameter within the
controller.
Assembly Working Addresses
- Fixed addresses directly related to their associ-
ated "Assembly Definition Addresses" (e.g., As sembly Working Addresses 200 & 201 will as sume the parameter pointed to by Assembly Defi nition Addresses 40 & 41).
When the Modbus address of a target parameter is
stored in an "Assembly Definition Address" its corresponding working address will return that parameter’s actual value. If it’s a writable parameter, writing to its working register will change the parameter’s actual value.
As an example, Modbus register 410 contains the
Analog Input 1 Process Value (See Operations Page,
Analog Input Menu). If the value 410 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 all
registers are set to Hardware ID.
The table (See Appendix: Modbus Programmable
Memory Blocks) identified as "Assembly Definition
Addresses and Assembly Working Addresses" reflects
the assemblies and their associated addresses.
Differences Between a User Without Password,
User With Password and Administrator
- User without a password is restricted by the
Locked Access Level [loC; l].
- A User with a password is restricted by the
Read Lockout Security [rloC] never having ac cess to the Lock Menu [`loC].
- An Administrator is restricted according to the
Read Lockout Security [rloC] however, the Ad ministrator has access to the Lock Menu where
the Read Lockout can be changed.

Software Configuration
Using EZ-ZONE® Configurator Software
To enable a user to configure the RMS control using
a personal computer (PC), Watlow has provided free
software 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
electronically 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 below 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 sub folder "EZ-ZONE Configurator"
4. Click on EZ-ZONE Configurator to run.
The first screen that will appear is shown below.
define the communications port on the PC to use.
The available options allow the user to select "Try
them all" or to use a specific known communications
port. After installation of your converter if you are
not sure which communications port was allocated
select "Try them all" and then click next. The screen
to follow shows that the software is scanning for
devices on the network and that progress is being
made.
If the PC is already physically connected to the EZZONE RMS control click the next button to go online.
Note:
When establishing communications from PC to
the RMS control an interface converter will be required. 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 EIA232 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 online.
After clicking the next button above it is necessary to
Watlow EZ-ZONE® RMS Module • 92 • Chapter 6 Features
When complete, the software will display all of the
available devices found on the network as shown belo w.
In the previous screen shot the RMS is shown high-
Page 96
lighted (address 6) to bring greater clarity to the control in focus. Any EZ-ZONE device on the network
will appear in this window and would be available
for the purpose of configuration or monitoring. After
clicking on the control of choice simply click the next
button once again. After clicking on Setup and then
Analog Input 1 the next screen appears below.
to that parameter will appear in the center column.
The grayed out fields in the center column simply
mean that this parameter does not apply for the type
of sensor selected. As an example, notice that when
RTD is selected,TC Linearization does not apply and
is therefore grayed out.
To speed up the process of configuration notice that
In the screen shot above notice that the device part
number is clearly displayed at the top of the page
(yellow highlight added for emphasis). When multiple
EZ-ZONE devices are on the network it is important
that the part number be noted prior to configuring so
as to avoid making unwanted configuration changes
to another control.
Looking closely at the left hand column (Parameter
Menus) notice that when first entering this screen it
displays all of the available Pages (Setup, Operations
and Factory) at a high level. After clicking on any
of the available pages the sub menus and associated
parameters for each will appear as shown above. The
Page structure as laid out within this software follows:
- Setup
- Operations
- Factory
Navigating from one Page to the next is easy and
clearly visible. Simply clicking on the plus symbol
next to Setup will expand the Setup Page where
all of the sub-menus will appear next. If a vertical
scroll bar appears click on the up or down arrow to
view all of the available menus on the selected page.
Once the focus is brought to an individual parameter
(single click of mouse) as is the case for Analog Input 1 in the left column, all that can be setup related
Watlow EZ-ZONE® RMS Module • 93 • Chapter 6 Features
at the bottom of the center column there is an operation to copy settings. If Analog Input 1 and 2 are
the same type of sensor click on "Copy Settings"
where a copy from to copy to dialog box will appear
allowing for quick duplication of all settings.
Notice too, that by clicking on any of those items in
the center column that context sensitive help will appear for that particular item in the right hand column.
Lastly, when the configuration is complete click the
"Finish" button at the bottom right of the previous
screen shot. The screen that follows this action can
be seen below.
Page 97
Although the RMS control now contains the configuration (because the previous discussion focused on
doing the configuration on-line) it is suggested that
after the configuration process is completed that the
user save this file on the PC for future use. If for
some reason someone inadvertently changed a setting without understanding the impact it would be
easy and perhaps faster to download a saved configuration back to the control versus trying to figure out
what was changed.
Of course, there is an option to exit without saving a
copy to the local hard drive.
After selecting Save above click the "Finish" button
once again. The screen below will than appear.
When saving the configuration note the location
where the file will be placed (Saved in) and enter the
file name (File name) as well. The default path for
saved files follows:
The user can save the file to any folder of choice.

Process Value Function
The Process Value (PV) function block accepts multiple inputs and performs a programmed math function to derive
an output value with Filter and Offset values applied. It
is assumed that no input error conditions apply. Some PV
operations must be performed in the user's units. Functions may combine multiple inputs. Those inputs may have
incompatible units from a logical point of view. As a result,
unless otherwise indicated, the presentation of the output
value is the same as Source A. This accommodates temperatures being multiplied, divided and offset by constants
and process inputs. Only inputs that have a source associated to them are used in the calculations.
