RP-Cs

BACnet/IP controller – RP-C is a room-purpose, fully programmable, IP based field controller. The RP-C models offer a flexible mix of I/O point types that suit a wide range of HVAC applications. The controller can either be used as a standalone BACnet/IP field controller or as part of an EcoStruxure BMS with an AS-P or AS-B server or an Enterprise Server as the parent server. The RP-C features a wireless chip that allows a mobile device running the eCommission SmartX Controllers mobile application to connect directly to the controller.

The RP-C allows for flexible control solutions due to the dual Ethernet ports, the interface to SpaceLogic Sensor devices, the interface for support of Connected Room Solution (CRS) devices, and the versatile mix of universal inputs/outputs, solid-state relay (SSR) outputs, relay outputs, and high power relay outputs.

When RP-Cs are part of an EcoStruxure BMS, you can take full advantage of the existing EcoStruxure Building Operation engineering tools.

RP-C 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.

For more information, see RP-C Models .

RP-C Onboard I/O

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.

For more information, see RP-C Onboard I/O .

RP-C Built-in Power Supply

The RP-C-12A, -12B, and -12C models have a built-in power supply designed to accommodate a nominal operating voltage of 24 VAC at 50/60 Hz or 24 to 30 VDC input power. The RP-C-16A model's power supply is designed for a nominal operating voltage of 230 VAC at 50/60 Hz.

For more information, see RP-C Built-in Power Supply .

BACnet/IP Controller Device Memory

BACnet/IP devices have three types of memory:

  • Flash memory: for boot loader, operating system, application software, and configuration storage

  • RAM: for runtime operation

  • FRAM non-volatile memory: for data retention in the case of power outage

For more information, see BACnet/IP Controller Device Memory .

BACnet/IP Controller Supported Building Standards

One of the cornerstones of the EcoStruxure BMS is support for open standards. As a result, the BACnet/IP controller complies with the BACnet open standard, one of the most popular standards for buildings.

For more information, see BACnet/IP controller Supported Building Standards .

RP-C Wireless Connectivity

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

For more information, see RP-C Wireless Connectivity .

RP-C Communication Ports

The RP-C provides the following combination of communication ports:

  • Two Ethernet ports

  • Two USB ports

  • Two RS-485 ports

For more information, see RP-C Communication Ports .

RP-C Sensor Bus

The RP-C sensor bus allows SpaceLogic Sensor devices to be connected to the controller.

For more information, see RP-C Sensor Bus .

RP-C Room Bus

The RP-C room bus allows RP controller 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.

For more information, see RP-C Room Bus .

RP-C Modbus

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

For more information, see RP-C Modbus .

RP-C Screw Terminals

The RP-C has fixed screw terminals for the power input, SSR outputs, relay outputs, high power relay outputs, and universal inputs/outputs.

For more information, see RP-C Screw Terminals .

RP-C LEDs

There is one LED on the front panel of the RP-C.

For more information, see RP-C LEDs .

RP Controller Reset Modes

You can reset and restart the RP controllers in different ways depending on how long you press the reset button. The resets and restarts can affect the retention of values after restart based on the retain levels configured for the variables.

For more information, see RP Controller Reset Modes .

RP-C Device Installation

The RP-C can be installed on a DIN rail or flat surface.

For more information, see RP-C Device Installation .

24 VAC Output on RP-C-16A Model

The RP-C-16A model has a 24 VAC (19 VA) Class 2 output that can be used to power external loads such as actuators, relays, or indicators. The external loads can be controlled using the controller's solid-state relay (SSR) or relay outputs.

For more information, see 24 VAC Output on the RP-C-16A Controller .

Wiring

The wiring recommendations provide guidance regarding wiring of the Central IO modules, automation servers, BACnet/IP devices, and RP controller expansion modules, and Operator Display.

For more information, see Wiring .

BACnet/IP Controller Device Firmware Management

Using WorkStation, you can update the firmware of multiple BACnet/IP devices and their attached SpaceLogic Sensor devices, RP controller expansion modules, and multi-sensors at the same time with minimum downtime. In particular, the universal upgrade package simplifies the update process and requires minimal user involvement and coordination.

Tip:

SpaceLogic Sensor devices, RP controller expansion modules, and multi-sensors are supported by the RP controller.

For more information, see BACnet/IP Device Firmware Management .
