Chapter 1: Overview

The EZ-ZONE® Rail Mount Access module (RMA)
takes the pain out of adding field bus protocols, data
logging and more to your RM system architecture.

It just got a whole lot easier to solve the thermal
requirements of your system. The RMA 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 control over a network this
module will meet the need. Communications proto­cols available as options with this module include
EtherNet/IP™, DeviceNet™, Modbus® RTU/TCP and
Profibus DP. Using your browser with an open con­nection to the internet, click on the link below and
browse Watlow's web site to find other complimenta­ry RM products and associated documentation.

A Conceptual View of the RM System

The f lexibility of the RM’s software and hardware al­lows a large range of configurations. Acquiring a bet­ter understanding of the controllers overall function­ality and capabilities while at the same time plan­ning out how the controller can be used will deliver
maximum effectiveness in your application.

The RM system at a high level can have a total
of 17 modules installed, only one of which can be an
RMA module and the others (16 maximum) can be
any combination of available RM modules. Each in­stalled RM module must have a unique Standard
Bus address (factory default is 1) ranging from 1-9,
A-F, H (10 -16). The Access module will be delivered
with a default Standard Bus address of 17 (J). If not
using the default zone address the user will need to
define each zone address via the button on the face of
each module.

The RMA can be considered an accessory RM
module in that by itself it has no PID control loops.
However, used in conjunction with an RM Control­ler (RMC) or RM High Density (RMH) module the
RME provides increased I/O capabilities. Outputs of
the RME can be used to drive output loads of various
kinds. For instance, an RME module could be placed
in a remote location (up to 200 feet away) from a PID
controller such as an RMC or RMH to drive a heater.

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. The RMA Module can provide:

• Multiple field bus protocols

• Data logging capabilities (up to 200 data points)

• Real Time Clock with Battery Backup

• Automatically (upon power restoration) re-en­able a profile to run after a power loss

• Auto-Configuration Backup

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.

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 200 feet. In this configuration the OIT
can communicate with all modules (maximum 16
modules any combination with one Access module).

A Conceptual View of RM Hardware Configurations

Due to the scalability and flexibility in the system
components a user has several options available in
the way that the hardware can be connected. Listed
below are a few examples.

RM System Connected to a Programmable Log­ic Controller (PLC) on a DIN Rail

In this configuration the PLC can be connected to
the RM system via the Access module using one or
more available protocols:

Module Orientation

The picture below reflects a front view of an RMA module. Like all RM modules, there are four slots that
appear on the face (slot A, B, D, and E) of the module and one on the bottom (slot C) not shown. For this
particular module only slots D and E can be used. On the face of the module there is a button (orange circle)
under the Zone address [J] that when pushed and held has the following function:

1.Push and hold for ~ 2 seconds to change the Zone address. Valid addresses range from 1 -17 ([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 Access module is shipped (default fac­tory address) at address [j] or 17

RMA 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.

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.

Connecting and Wiring the Modules

ter-module

RM System Connections

Components of a RM system can be installed as
stand alone modules or can be interconnected on
the DIN rail as shown below. When modules are
connected together, 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 of the RM modules shown below on the DIN
rail can use it.

Modular backplane interconnect

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:

1. 90-264 Vac to 24Vdc @ 31 watts (Part #:
0847-0299-0000)

2. 90-264 Vac to 24Vdc @ 60 watts (Part #:
0847-0300-0000)

3. 90-264 Vac to 24Vdc @ 91 watts (Part #:
0847-0301-0000)

With regards to the modular loading affect, max­imum power for each is listed below:

1. RMCxxxxxxxxxxxx @ 7 watts

2. RMEx-xxxx-xxxx @ 7 watts

3. RMAx-xxxx-xxxx @ 4 watts

So, in the split rail system diagram, the maxi­mum current draw on the supply would be 38
Watts.

- 2 RMC modules consumes 14W

- 2 RME modules consumes 14W

- 1 RMA module consumes 4W

- 1 Remote User Interface consumes 6W

With this power requirement 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 per-

taining 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

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 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.

The RMA module comes with the standard offering
of Watlow's Standard Bus protocol used primarily
for inter-module communications as well as for con­figuration using EZ-ZONE Configurator software
(free download from Watlow's web site (http://www.

watlow.com). Along with Standard Bus, the RMA

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 controls support 6 digit Modbus regis­ters.

Note:

In this User's Guide, all values shown representing
Modbus addresses are added to 400,001 or 40,001 to
acquire the absolute address. As an example, notice
above (under the Range header) the Modbus address
identified for Backup. Compare this to the value list­ed for this same parameter found in the Operations

Watlo w EZ - Z ONE® R M A M o dule • 19 • Cha p t e r 2 I n s tal l an d Wi r e

Page under the Backup Menu.

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 RMA Setup
Page for the Real Time Clock Value. Find the column
identified in the header as Modbus and notice that it
lists register 1424. Because this parameter is a float
it is actually represented by registers 1424 (low or­der bytes) and 1425 (high order bytes). The Modbus
specification does not dictate which register should
be high or low order so Watlow provides the user the
ability to swap this order (Setup Page, Communica­tions Menu) from the default low/high to high/low.

It should also be noted that some of the cells in the
Modbus column contain wording pertaining to an
offset. Several parameters in the RMA contain more
than one instance; such as, Data Log points (250),
Variables (12), Gateway Instances (16), etc... The
Modbus register shown always represents instance
one. Take for an example the logging point param­eter found in the RMA Setup Page under the Log
Point Menu. Instance one for the Source Function
is shown as address 1470 and the offset to the next
instance is identified as +16. If there was a desire to
read or write to instance 3 simply add 32 to 1470 to
find its address, in this case, the instance 3 address
for Log Point Source Function 3 is 1502.

Common Industrial Protocol (CIP)
DeviceNet & Ethernet/IP

Both DeviceNet and EtherNet/IP use open object
based programming tools and use the same address­ing scheme. In the following menu pages notice the
column header identified as CIP. There you will find
the Class, Instance and Attribute in hexadecimal,
(decimal in parenthesis) which makes up the address­ing for both protocols.

Profibus DP

To accommodate for Profibus DP addressing the fol­lowing menus contain a column identified as Profibus
Index. Data types used in conjunction with Profibus
DP can be found in the table below.

Data Types Used with Profibus DP

Word = Unsigned 16 bit

INT = Signed 16-bit Integer

dint = Signed 32-bit Integer

REAL = Float, IEEE 754 32-bit

CHAR = ASCII, 8 bits per character

BYTE = 8 bits

RMA _ - A [6] _ _ - A A _ _

To learn more about the Profibus DP protocol point
your browser to http://www.profibus.org

Note:

The RMA module equipped with EtherNet/IP supports
implicit and unconnected explicit messages.

Data Types Used with CIP

uint = Unsigned 16 bit integer

int = Signed 16-bit

dint = Signed 32-bits, long

real = Float, IEEE 754 32-bit

string = ASCII, 8 bits per character

sint = Signed 8 bits , byte

RMA _ - A [3] _ _ - A A _ _
