Watlow EZ-ZONE® RMS Module • 3 • Chapter 1 Overview

Introduction

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).

Watlow EZ-ZONE® RMS Module • 4 • Chapter 1 Overview

A Conceptual View of the RMS

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.

A Conceptual View of RM Hardware Configurations

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.

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

Watlow EZ-ZONE® RMS Module • 6 • Chapter 1 Overview

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).

Watlow EZ-ZONE® RMS Module • 7 • Chapter 1 Overview

Getting Started Quickly

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

Note:

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.

RMS Installation and Removal on a DIN Rail

Modular Backplane Connector

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.

Watlow EZ-ZONE® RMS Module • 17 • Chapter 2 Install and Wire

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.

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.

Internal Circuitry

Internal Supply

As an open collector output (see graphic below), use an external power sup­ply with the negative wired to B_, the positive to the coil of a pilot mechani­cal relay and the other side of the coil wired to the output of choice (D_).
Each open collector output can sink 1.5 A with the total for all open collector
outputs not exceeding 8 amperes. Ensure that a kickback diode is reversed
wired across the relay coil to prevent damage to the internal transistor.
