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

A Conceptual View of the RM System

The flexibility of the RM system software and hardware allows for a large range of configurations. Focusing on the RME module, acquiring a better understanding of its overall functionality and capabilities while at the same time planning out how this module 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, one of which can be an Access 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 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 RME 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. 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)

When using this module, either as a stand-alone module or used in conjunction with any other RM module it is useful to remember that each process needs to be thought out carefully and the controller’s inputs, functions and outputs configured properly.

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.

What is an Instance?

The RM system can have many I/O points, in some cases, as described above, I/O can be placed in remote locations. For example, an RME module can have 24 digital I/O where each would be numbered from 1 to 24 and each would be considered a unique instance. They are named Digital I/O 1, 2, 3, etc... These instance numbers are then used when you link inputs, functions and outputs within a module or when linked to other modules. For example, when configuring an RME output for heat the control loop instance (1, 2, 3 or 4) and zone (1 to 16) to drive the output must be defined.

Functions

Functions, in simple terms, use input signals (realworld or internal), to calculate a value and deliver an output. A function may be as simple as configuring the function of the digital output, e.g., alarm, heat, etc..., or defining a set point for an alarm state to turn on or off.

To set up a function, one of the first things that must be considered is the function source and instance. For example, if the control is equipped with Digital Inputs (source) and it was decided to use DI 9 (instance) it can then be associated with an Action to reset an individual alarm or all alarms. The steps below, walk through this configuration:

Setup Page (Digital I/O Menu)

1. Navigate to the Setup Page and then to the Digital

I/O menu.

2. Select the desired instance and set the direction to

input voltage or input dry contact.

Setup Page (Action Menu)

3. Navigate to the Setup Page and then the Action

menu.

4. Set the Action Function to Alarm

5. Select which alarm instance will be reset (0 equals

all)

6. Select the Source Function to Digital I/O

7. Select the Source Instance (step 2 above)

8. Select the Source Zone (0 equals the module being

configured).

9. Select the Active Level to execute the desired func-

tion.

When the selected digital input is active the alarm or all alarms that are latched without a currently existing alarm condition will be reset. If a specific alarm instance (1 - 8) is selected (step 5 above), it will be

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

that instance alone that will be reset.

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 non-latching (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.

Some functions have a hardware input for which the source/s are preset and cannot be changed. As an example, CT 1 source function comes not surprisingly, from the CT attached to it. Most functions can accept more than one input and it would not be uncommon to see the output of one function (internal) serve as an input to another, as would be the case with a compare function. The source parameters for the first input to a function are called Source Function A, Source Instance A and Source Zone A and the second input, Source Function B, Source Instance B and Source Zone B and so on.

Inputs

The inputs provide the information that any given programmed function can act upon. This information may come from an operator pushing a button, or as part of a more complex function it may represent one of ten inputs used for the Linearization function.

Each digital input reads whether a device is active or inactive. An RME module can be equipped with up to 24 digital inputs, where the RM system can have many more. Each digital I/O point must be configured to function as an input or an 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 CT and one that is tied to an internal function.

RMC module

- The logic block (within the RME module) is configured as an OR function

- The RME output function is tied to the internal output of the logical OR function

When either process alarm is true (analog input value is greater than the alarm high set point, the realworld output connected to the RME will be driven on.

Outputs

Outputs can perform various functions or actions in response to information provided by a function, such as a digital output to turn a light on or off, unlocking a door; or turning on a buzzer.

Assign a function to an output in the Output Menu or Digital Output Menu of the Setup Page. Then select which instance 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.

You can assign more than one output to respond to a single instance of a function, e.g., 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, Logic function, etc..) the Action function can cause other functions to occur. To name a few, silencing alarms, turn control loops off and placing alarms in non-alarm state.

Function

In the example above one can see the Current function on the left which is connected to a real-world input device (CT) where on the far right the internal output of the Alarm function is tied to the input of the Output function where a real-world output device is then driven such as a siren or a flashing light.

With a slight modification of the graphic above the example below now ties the real-world analog inputs from an RMC module directly to its PID control. The RME module is using the same analog input to drive an alarm function. For the sake of this example the following is true:

- Within the RME two unique high process alarms are configured for analog inputs 1 and 2 of the

RME 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® RME Module • 14 • 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.

Connecting and Wiring the Modules

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. 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.

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.
