RP-C

Introduction

SmartX IP Controller – RP-C is a room-purpose, fully programmable, IP based field controller that suits a wide range of HVAC applications. The RP-C can either be used as a standalone BACnet/IP field controller or as part of an EcoStruxure BMS with a SmartX AS-P or AS-B server or an Enterprise Server as the parent server. The RP-C features a wireless chip that allows the mobile commissioning application and the mobile application for room comfort settings to connect directly to the controller.

The RP-C has the following features:

• IP enabled with dual-port Ethernet switch

• Full range of controller models

• Versatile onboard I/O point mix

• Optional covers

• Wireless connectivity

• Highly available

• Configurable RS-485 ports

• Sensor bus for living space sensors

• Room bus for connected room solutions

• Modbus network

• KNX support

• Engage mobile application for room comfort settings

• Mobile commissioning application

• Full EcoStruxure Building Operation software support, providing efficient engineering tools

IP connectivity and flexible network topologies

The SmartX IP controllers are based on open protocols that simplify interoperability, IP configuration, and device management:

• IP addressing

• BACnet/IP communications

• DHCP for easy network configuration

The SmartX IP controllers have a dual-port Ethernet switch, which enables flexible network topologies:

• Star

• Daisy chain

• Rapid Spanning Tree Protocol (RSTP) ring

In a star topology, the controller and the parent EcoStruxure BMS server are individually connected to an Ethernet switch. Daisy-chain multiple controllers together to reduce installation time and cost. Use an RSTP ring topology when you want a non-operational controller to be detected and recovered quickly and efficiently.

Full range of controller models

The RP-C comes in four different models, which offer four different sets of I/O point types, named 12A, 12B, 12C, and 16A. The RP-C-12A, -12B, and -12C models support 24 VAC/DC power supply, whereas the RP-C-16A model is a 230 VAC model.

Fully programmable

The fully programmable RP-C models provide flexibility through support of both Script and Function Block programming options. The RP-C promotes efficiency and standardization through the use of standard controller applications.

Models with a versatile mix of I/O points

The RP-C-12A, -12B, -12C, and -16A models provide 12 or 16 I/O points, consisting of four different sets of I/O point types. The versatile mix of I/O point types match a wide variety of applications. The universal inputs/outputs are highly flexible and can be configured as either inputs or outputs.

Table: I/O Point Types by RP-C Models

Table: Configurations by I/O Point Types

The universal inputs/outputs are ideal for any mix of temperature, pressure, flow, status points, and similar point types in a building control system.

As counter inputs, the universal inputs/outputs are commonly used in energy metering applications. As RTD inputs, they are ideal for temperature points in a building control system. As supervised inputs, they are used for security applications where it is critical to know whether or not a wire has been cut or shorted. These events provide a separate indication of alarms and events in the system.

For all analog inputs, maximum and minimum levels can be defined to automatically detect over-range and under-range values.

The universal inputs/outputs are capable of supporting analog outputs of type voltage outputs. Therefore, the universal inputs/outputs support a wide range of devices, such as actuators.

Only devices with safe extra low voltage equipment (SELV/PELV) inputs/outputs should be connected to the controller universal inputs/outputs.

The solid-state relay (SSR) outputs can be used in many applications to switch 24 VAC or 24 VDC on or off for external loads such as actuators, relays, or indicators. SSRs are silent and are not adversely affected by relay contact wear.

The relay outputs support digital Form A point types. The Form A relays are designed for direct load applications.

The high power relay output is of type Form C. The normally-open (NO) contact is ideal for switching resistive loads of up to 12 A, such as electrical heating elements. The normally-closed (NC) contact can be used to switch inductive loads of up to 3 A.

Optional covers

All RP-C models can be equipped with optional covers to reduce access to the screw terminals and wires.

Wireless connectivity

RP-C is a Bluetooth Low Energy (BLE) enabled product. You can use this wireless connectivity option to connect the RP-C with a smartphone or tablet running the eCommission SmartX Controllers mobile application or the Engage mobile application for room comfort settings.

Through Wireless Adapter - Advanced connected to the host USB port, Zigbee ^TM wireless connectivity can be enabled for the RP-C. The controller can extend its point count through the Zigbee wireless network and bring flexibility in your applications. For more information on the adapter and supported wireless devices, see the Wireless Adapter - Advanced Specification Sheet.

Highly available

The SmartX IP controllers support local trends, schedules, and alarms, enabling local operation when the controller is offline or used in standalone applications.

The battery-free power backup of the memory and real-time clock helps prevent data loss and allows seamless and quick recovery after a power disruption.

In WorkStation, you update the firmware of multiple SmartX IP controllers at the same time and with minimum down time. The EcoStruxure BMS server keeps track of the installed firmware to support backup, restore, and replacement of the controllers and sensors. The server can host controllers of different firmware versions.

Configurable RS-485 ports

The RP-C controller has two configurable RS-485 ports, which can be configured to support three different types of networks:

• Sensor bus

• Room bus

• Modbus network

The RP-C controller can run one of each network type.

Sensor bus for living space sensors

The SmartX IP controllers provide an interface designed for the SmartX Sensor family of living space sensors. The SmartX Sensors offer an efficient way to sense the temperature, humidity, CO ₂ , and occupancy in a room. The SmartX Sensors are available with different combinations of sensor types and various covers and user interface options, such as touchscreen, setpoint and override buttons, and blank covers.

 

action_zoom_plus_stroke

The sensor bus provides both power and communications for up to four sensors that are daisy-chained using standard Cat 5 (or higher) cables. The maximum number of sensors that can be connected to a controller varies depending on the sensor model and the combination of cover and sensor base type:

• Blank covers: Up to four sensors of any combination of sensor base types

• 3-button and touchscreen covers:

  • Up to two sensor bases with CO ₂ option

  • Up to four sensor bases without CO ₂ option

• SmartX LCD temperature sensors: Up to four sensors are supported

The maximum total length of the sensor bus is 61 m (200 ft). For more information, see the SmartX Living Space Sensors Specification Sheet.

Room bus for connected room solutions

The RP-C room bus allows RP Series expansion modules and multi-sensors to be connected to the controller for motion detection, luminosity measurements, communication with remote control (RP-C-RC-BLE), and control of electric lights and window blinds.

The RP-C room bus supports up to six connected RP Series expansion modules and multi-sensors with the following restrictions:

• Maximum of two DALI light modules

• Maximum of two SMI blind modules

• Maximum of four multi-sensors

Maximum total length of the room bus is 72 m (236 ft).

For more information, see the Specification Sheets for the RP Series Expansion Modules.

Modbus network

The RP-C Modbus network allows standard Modbus devices and the KNX Modbus gateway (RP-C-EXT-KNX) to be connected to the controller.

The Modbus RTU protocol is used for the communication. The RP-C controller acts the Modbus master and the connected devices act as slaves.

The maximum number of Modbus devices that can be connected to an RP-C controller depends on the type of Modbus device and the number of Modbus registers.

The RP-C Modbus network supports up to 10 connected Modbus devices with the following restrictions:

• Maximum of one KNX Modbus gateway (RP-C-EXT-KNX)

• Maximum of 250 Modbus registers

The RP-C Modbus network does not support 64-bit Modbus registers.

KNX support

Through the KNX Modbus gateway (RP-C-EXT-KNX), the RP-C controller can communicate with KNX devices such as push-buttons and sensors.

The KNX Modbus gateway provides a KNX to Modbus interface that connects to one of the RP-C controller's configurable RS-485 ports.

For more information, see the RP-C-EXT-KNX Specification Sheet.

Engage mobile application

The Engage mobile application enables control of room temperature, fan speed, lights, and blinds/shades directly from a smartphone. A user can manage these settings when the application is connected to the RP-C controller.

The Engage mobile application is free and available for download from Google Play and Apple App Store.

For more information, see the Engage Specification Sheet.

Mobile commissioning application

The eCommission SmartX Controllers mobile application is designed for local configuration, field deployment, and commissioning of SmartX IP controllers. The mobile application reduces the commissioning time, allows flexibility in project execution, and minimizes dependencies on network infrastructure.

The mobile application is designed for use with Android, Apple (iOS), and Microsoft Windows 10 devices. For more information, see the eCommission SmartX Controllers Specification Sheet.

 

action_zoom_plus_stroke

Using the eCommission SmartX Controllers mobile application, you can connect to one or many RP-Cs. You can connect to a single RP-C using the controller's built-in Bluetooth connectivity or using the eCommission Bluetooth Adapter connected to a SmartX Sensor. Using a wireless access point or a network switch, you can connect to a network of RP-Cs on the local IP network.

With the eCommission SmartX Controllers mobile application, you can easily discover SmartX IP controllers on the IP network. You can change the configuration of each controller, including the BACnet and IP network settings, location, and parent server. To save engineering time, you can save common device settings and then reuse them for controllers of the same model.

The eCommission SmartX Controllers mobile application does not require an EcoStruxure BMS server or a network infrastructure to be in place. You can use the mobile application to load the controller application directly into the local SmartX IP controller and deploy the controller. The controller application can be created offline using Project Configuration Tool or WorkStation. You can use the mobile application to change the behavior of an installed standard controller application, such as configuring temperature setpoints. You can also perform an I/O checkout to verify that the controller's I/O points are configured, wired, and operating correctly.

The technician or electrician can perform I/O checkout on the RP-C room bus to verify proper communication over the room bus between the RP-C and the associated RP Series expansion modules. Module type mismatches or address mismatches can then be resolved. After wiring the physical inputs and outputs of the RP Series expansion modules, the technician or electrician can perform the following tasks on the different modules:

• DALI light modules: discover, wink, and associate DALI lights with the logical software points, and test individual lights

• 0-10V light modules: test individual lights

• Blind modules: calibrate and test blinds

• Relay module: test outputs

Full EcoStruxure Building Operation software support

The power of the RP-C controller is fully realized when it is part of an EcoStruxure BMS, which provides the following benefits:

• WorkStation/WebStation interface

• Script and Function Block programming options

• Device discovery

• Engineering efficiency

• Preconfigured HVAC applications

WorkStation and WebStation provide a consistent user experience regardless of which EcoStruxure BMS server the user is logged on to. The user can log on to the parent EcoStruxure BMS server to engineer, commission, supervise, and monitor the SmartX IP controller and its I/O as well as its attached SmartX Sensors. For more information, see the WorkStation and WebStation specification sheets.

The fully programmable RP-C controller models have both Script and Function Block programming options. Existing programs can easily be reused between the EcoStruxure BMS server and the controller.

The enhanced Device Discovery in WorkStation enables you to easily identify SmartX IP controllers on a BACnet network and to associate the controllers with their parent server.

The engineering and maintenance of SmartX IP controllers can be done very efficiently using the EcoStruxure Building Operation reusability features. With these features, you can create library items (Custom Types) for a complete controller application that contains programs and all necessary objects such as trends, alarms, and schedules. The controller application in the Custom Types library is reusable across all controllers of the same model. You can use the controller application as a base for creating new controllers intended for similar applications. You can then edit the controller application, and the changes are automatically replicated to all controllers, while each controller keeps its local values.

WorkStation supports both online and offline engineering of SmartX IP controllers. You can make the configuration changes online or use database mode to make the changes offline. In database mode, the changes are saved to the EcoStruxure Building Operation database so that you can apply the changes to the controllers later.

Project Configuration Tool enables you to perform all the engineering off site, without the need for physical hardware, which minimizes the time you need to spend on site. You can run the EcoStruxure BMS servers virtually and engineer the SmartX IP controllers before you deploy your server and controller applications to the servers and controllers on site. For more information, see the Project Configuration Tool specification sheet.
