Watlow EZ-ZONE® RMA Module • 5 • Chapter 1 Overview

A Conceptual View of the RM System

The exibility of the RM family modules and software allows for a large range of congurations. Acquiring a better understanding of the application requirements and then the overall functionality and capabilities of each RM module will help to ensure maximum system performance.

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 for an RMA is J while all other RM modules would be 1) ranging from 1-я, A-F (10 -15) and h (16). Default zone addresses can be changed on any RM module using the button on the face of each module. Ensure that each module has a unique address.

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 Control (RMC), RM High Density (RMH) or an RM Expansion (RME) module, it could be placed in a remote location up to 200 feet away from any of the other RM modules on the network. While in a remote location, the RMA is

still fully capable of using all of its features, such as, the real time clock (used with proles)

and data logging. This can be done while also providing communications to / from a master

device on the eldbus network.

Some of the user selectable ordering options are listed below:

1. Class 2 or SELV (Saftey Extra Low Voltage) equivalent 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 eld bus protocols

• Data logging capabilities (up to 200 data points)

• Real Time Clock with Battery Backup

• Automatically (upon power restoration) re-enable a prole to run after a power loss

• Auto-Conguration Backup

Note:

All RM modules can share data 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.

RM System Configurations Using and RMA

Due to the scalability and exibility in the system components a user has several options

available in the way that the hardware can be connected.

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

RM 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

To install the backplane follow the steps below:

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)

2. Next, rotate back plane assembly downward to engage the lower edge of the rail.

Note:

Din Rail clipping distance ranges from

1.366 -1.389 inches. The back plane assembly will not latch onto the rail successfully if the rail is out of dimension.

3. For nal 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 bottom side of the back plane assembly).

Note:

For easy removal and placement of modules it is recommended that there be a 76.2 mm (3.00 in) clearance on the top, bottom and front of each module.

Watlow EZ-ZONE® RMA Module • 14 • Chapter 2 Install and Wire

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.

To install backplane connectors follow the steps below:

1. Attach individual modules to the rail separately.

2. Laterally slide the modules together until they touch.

3. 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.

Module Installation

In the picture to the right notice that the arrow is pointing at the top lip of the module (on side).

To install modules on the backplane follow the steps below:

1. Slide the lip of the module over the top of the Modular Backplane Connector and then push down on the rear of the module. The module will then slide over the two posts just above the green connector (see pictures below).

Connecting and Wiring the Modules

Use twisted pair sheilded wire for

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 sufcient. 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.

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 conguration scenario

that could present itself (graphic not shown) would be a conguration that re-

quires 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 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.

Watlow EZ-ZONE® RMA Module • 22 • Chapter 2 Install and Wire

When using a split rail conguration ensure that the interconnections for the Inter-module

Bus and Standard Bus do not exceed 200 feet.

Note:

Module is not provided with a disconnect, use of an external disconnect is required. It should be located in close proximity to the module and be labeled as the disconnect for the module.

Note:

Connecting power supplies in parallel is not allowed. When power consumption is greater than 91 watts use a split rail configuration.

Wiring a Serial EIA-485 Network

Do not route network wires with power wires. Connect network wires in daisy-chain fashion when connecting multiple devices in a network. A termination resistor may be required.

Place a 120 Ω resistor across T+/R+ and T-/R- of the last con-troller on a on a network.

Note:

Termination resistors when used, require a termination resistor at both ends of the network.

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 Backup

Menu. To Save a conguration backup of all connected zones using Modbus simply right the value of 1646 (save) to Modbus register 1270.

Communication Protocols

All RM modules come with the standard offering of Watlow's Standard Bus protocol used primarily for inter-module communications as well as for conguration using EZ-ZONE Congurator and Composer software (free download from Watlow's web site (http://www.watlow.

com). Along with Standard Bus, the RMH module can also be ordered with Modbus RTU (only

one protocol can be active at any given time). The RMA module has options for several different protocols listed below:

- Modbus RTU 232/485

- EtherNet/IP, Modbus TCP

- DeviceNet

- Probus DP

To learn more about any of the available RM modules, click on the link below. Once there

simply type in RM in the Keyword eld. http://www.watlow.com/literature/manuals.cfm

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).

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.

For parameters listed as oat 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 Analog pa-

rameter under the Variable menu. Find the column identied in the header as Modbus Relative Address, notice that it lists register 1034. Because this parameter is a oat it is actually

represented by registers 1034 (low order bytes) and 1035 (high order bytes). The Modbus

specication 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 (200), Gateway Instances (17), etc... The Modbus register shown always represents instance one. Take for an example the Log 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 identied as +16. If there was a desire to read or write to instance 3, simply add 32 to 1470 to nd the appropriate address; in this case, Log Point Source Function 3 address would be identied as 1502.

DeviceNet & Ethernet/IP

Both DeviceNet and EtherNet/IP use open object based programming tools and are based on the Common Industrial Protocol (CIP). Due to the use of CIP as the foundation of either protocol (DeviceNet or EtherNet/IP), they both use the same addressing scheme and parameter

addresses can be found in the column header identied as CIP. There you will nd the Class,
