Watlow EZ-ZONE®RM System •2 •Chapter 1 Overview
Chapter 1: Overview
1
The EZ-ZONE®Rail Mount (RM) system takes
the pain out of solving your thermal loop require-
ments whether it be for a single loop, multi-loop,
stand-alone, or distributed control applications.
Watlow’s EZ-ZONE RM control system offers op-
tions to reduce application complexity and the cost of
control-loop ownership. The system can be designed
to include one or more RM-Control Modules (with up
to four loops), one or more RM-Expansion Modules
(for additional discrete inputs and outputs), and a
RM-Access Module (for communications, configura-
tion backup, real-time clock and data logging). The
modules (up to 16, 17 including an Access module)
can be connected together on the DIN rail minimiz-
ing wiring, or they can be separated. You can order
the EZ-ZONE RM as a single or multi-loop PID con-
troller or an over-under limit controller, or you can
combine both functions. The system allows for op-
tional integration of high-amperage power controller
outputs, limits and controllers all in space-saving,
rail-mount packages. You can also select from a
number of serial communications options to help you
manage system performance.
It just got a whole lot easier to solve the thermal
requirements of your system. Because the EZ-ZONE
RM system is highly scalable, you only pay for what
you need. Ordering options allow for 1 to 64 loops, 1
to 384 I/O points, and various communications op-
tions. So, if you are looking for a stand-alone or net-
worked PID controller, an over-under limit controller
or an integrated controller, the EZ-ZONE RM sys-
tem is the answer.

Watlow EZ-ZONE®RM System •4 •Chapter 1 Overview
A Conceptual View of the RM System
The flexibility of the RM’s software and hardware al-
lows a large range of configurations. Acquiring a bet-
ter understanding of the controller’s overall function-
ality and capabilities while at the same time plan-
ning out how the controller can be used will deliver
maximum effectiveness in your application.
The system at a high level can have a total of 17
modules installed, one of which can be an Access
module and the others (16 maximum) can be any
combination of Control or Expansion modules. With
the exception of the Access module, the user will de-
fine each address via the button on the face of each
module. Each installed Control or Expansion module
must have a unique Standard Bus address ranging
from 1-9, A-F, H. The Access module will be delivered
with a default Standard Bus address of 17 (J).
The RMC (Controller) can be ordered with up to
four loops with default loop configurations (all loops)
out of the box as follows:
Analog Input functions set to thermocouple, type•
J
Control loops 1 through 4 use Analog Inputs 1•
through 4 respectively
Heat algorithm set for PID, Cool set to off•
Control mode set to Auto•
Set point set to 75° F•
So, for a heating application, to complete a heating
loop configuration simply configure one or more out-
put functions as Heat Power.
Note:
Zones can communicate with one another over the
backplane (local and split rail). Once the system is
configured and running changing zone addresses
without careful deliberation may cause disruption in
operation.
Some of the user selectable ordering options are
listed below:
1. Class 2 or SELV (Saftey Extra Low Voltage) equiv-
alent Power Supplies:
90-264 Vac to 24Vdc @ 31 watts•
90-264 Vac to 24Vdc @ 60 watts•
90-264 Vac to 24Vdc @ 91 watts•
2. RM Control Module can provide:
1 to 4 control loops, limits or CT inputs•
1 to 9 inputs (various types)•
1 to 12 outputs (various types)•
Modbus RTU communications•
3. RM Expansion Module can provide:
1 to 24 Digital Inputs/Outputs (I/O)•
4 to 12 Form A Mechanical Relays•
2 to 4 Form A 10A Solid-State Relays•
4 inputs for external Current Transformers•
(CT)
4. RM Access Module can provide:
Communications - DeviceNet, EtherNet/IP,•
Modbus RTU/TCP
Battery Backup•
Real Time Clock•
Data Logging•
Auto-Configuration Backup•
As can be seen above the RM system is fully scalable
with regards to power requirements, number of loops,
inputs, and outputs.
It is useful to think of the controller in three
parts: inputs (analog and digital), functions (math,
logic, PID, etc.), and outputs (relay, SSR, switched
DC, analog and or digital). Information flows from
an input to a function to an output when the control-
ler is properly configured. A single RM controller can
carry out several functions at the same time; for in-
stance: mathematical operations, closed-loop control,
monitoring for several different alarm situations and
operating switched devices, such as lights and mo-
tors. Each process needs to be thought out carefully
and the controller’s inputs, functions and outputs
configured properly.
What is an Instance?
The RM system has lots of features, in most cases
more than one. For example, an RM module can have
four control loops. They are named Control Loop 1,
Control Loop 2, Control Loop 3 and Control Loop 4.
Each is an instance of a control loop. They are num-
bered, 1, 2, 3 or 4 to distinguish between them and
that number indicates the specific instance of a con-
trol loop in the module. These instance numbers are
used when you link inputs, functions and outputs.
For example, when configuring a heat output the
control loop instance (1, 2, 3 or 4) to drive the output
must be defined.
Functions
Functions, in simple terms use input signals (real-
world or internal), to calculate a value and deliver an
output. A function may be as simple as configuring
the function of the analog input, i.e., thermocouple,
RTD, etc., or reading a temperature to set an alarm
state to on or off. Or, in differential control it could be
looking at the difference between two inputs for the
purpose of establishing a new set point value.
To use a function you will typically select the
source of its inputs and set its other options as well.
Some functions have a hardware input for which the
sources are preset and cannot be changed. The Ana-
log Input 1 function's input comes, not surprisingly,
from the sensor attached to the RM's first analog in-
put. Most functions, however, get their inputs from
other function's outputs. For example, the function
Alarm 1, can get its input from a variety of sources
including any of the instances of analog inputs or
current transformers in the controller. To select an
input for a function, you set the function's Source
Function, Source Instance and Source Zone param-
eters. To set Alarm 2 to monitor Analog Input 3
in a module with zone address 8, you set Alarm 2's
Source Function to "Analog Input", Source Instance
to "3" and Source Zone to "8". Most functions can ac-
cept more than one input. The source parameters for
the first input to a function are called Source Func-

Watlow EZ-ZONE®RM System •5 •Chapter 1 Overview
Outputs
Outputs can perform various functions or actions in
response to information provided by a function, such
as the output of the control; using a digital input or
output to turn a light on or off, unlocking a door; or
turning on a buzzer.
Assign an output to a function in the Output
Menu or Digital I/O Menu. Then select which in-
stance of that function will drive the selected output.
For example, you might assign an output to respond
to an internal output of a compare function or to re-
transmit the value of analog input 2 (instance 2).
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.
Input Events and Output Events
Input and output events are internal states that are
used exclusively by profiles. The source of an event
input can come from a real-world digital input or an
output from another function. Likewise, event out-
puts may control a physical output such as an output
function block or be used as an input to another func-
tion.
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, starting and
stopping a profile, silencing alarms, turncontrol loops
off and placing alarms in non-alarm state.
A Conceptual View of RM Hardware Configurations
Due to the scalability and flexibility in the sys-
tem components a user has several options available
in the way that the hardware can be connected. List-
ed below are a few examples.
RM System Connected to a Remote User Inter-
face (RUI) and a PC
In this configuration the RUI and PC are con-
nected to the RM system via Watlow's Standard Bus
where both will be able to talk directly to the RM

Slot CSlot C
Controller and the RM Expansion module. The PC

tion A, Source Instance A and Source Zone A and for
the second input Source Function B, Source Instance
B and Source Zone B and so on.
It should be noted that once a function is config-
ured caution should be observed when considering
changing zone addresses. For example, an alarm may
be set to respond to a real-world digital input from
instance 1 of another module (different zone). If the
zone address is changed where the digital input actu-
ally resides the alarm will no longer work.
Keep in mind that a function is a user-pro-
grammed process that may or may not perform an
action outside of the controller. It would not be un-
common to see the output (internal) of one function
serve as an input to another, as would be the case
with a compare function. To have any effect outside
of the controller, an output (real-world) function must
be configured to respond to some other function.
Inputs
The inputs provide the information that any given
programmed function can act upon. In a simple form,
this information may come from an operator push-
ing a button, or as part of a more complex function it
may represent a remote set point being received from
another zone.
Each analog input can be configured for therm-
istors, thermocouples, or RTDs to read the process
variable. It can also read mV/volts, current or resis-
tance, enabling usage of various devices to read hu-
midity, air pressure, operator inputs and other val-
ues. The settings in the Analog Input Menu (Setup
Page) for each analog input must be configured to
match the device connected to that input.
Each digital input reads whether a device is ac-
tive or inactive. A RM system can be equipped with
multiple digital I/O. Each I/O point must be config-
ured to function as either an input or output with the
direction parameter in the digital I/O Menu (Setup
Page).
Another concept that needs to be understood is
the difference between an input tied to a real-world
device such as a thermocouple and one that is tied to
an internal function.

In the example above one can see the analog input
function on the left which is connected to the real-
world input device where on the far right the same
can said for the output function as well. The control-
ler, when shipped from the factory (default state) has
real-world analog input 1 tied to the PV function
source A input. Its internal output serves as the in-
put to the control function. Lastly, in this example,
the output of the control function (perhaps heat or
cool) serves as the input to the output function where
a real-world output device is then driven.

In this configuration the control module connected

Modbus communications takes place between the
HMI and the control it is connected to. The RM back-
plane is always using the Standard Bus protocol. If
it is desired that the HMI communicate to both con-
trol modules, both control modules would need Mod-
bus communications and then pins CC, CA, and CB
would need to be daisy chained together.

Watlow EZ-ZONE®RM System •7 •Chapter 1 Overview
Module Orientation
The picture below represents one of three possible
RM modules. All three 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 (white circle) under the Zone address (5) that
when pushed and held has the following functions:
1. For any module, push and hold for ~ 2 seconds to
change the Zone address
2. For the control module, if equipped with the Mod-
bus protocol (RMCxxxxxxxxx1xx) pushing and
holding this button for ~ 6 seconds will cause the
display to reflect Pfor protocol. Releasing the
button and then pushing it again (within 6 sec
onds) the display will toggle between N(Modbus)
and S(Standard Bus). Valid addresses for Modbus
and Standard bus range from 1 -16 (1- 9, Ais 10,
Bis 11, Cis 12, Dis 13, Eis 14, Fis 15, and his
16). The Access module is shipped at address Jor

RM Installation and Removal on a DIN Rail
Modular Backplane Connector
The picture on the right shows the Modular Back-
plane 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 geom-
etry that facilitates accurate and consistent intercon-
nections. 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 lock-
ing 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 in-
stalling 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.

Warning: ç
Explosion hazard for hazardous lo-
cations. Do not disconnect while the
circuit is live.
Removal of the Modular Back-
plane 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.
Module Removal
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.
