RP-V Room Bus

The RP controller room bus allows RP controller expansion modules to be connected to the controller for people counting, motion detection, luminosity and sound pressure level measurements, Bluetooth Low Energy based applications, and control of electric lights and window blinds.

Aviso

RP controller models with “-M” in the product name do not support the room bus.

The room bus is a proprietary RS-485 bus, which is designed to provide both 24 VDC power supply and communications for the connected RP controller expansion modules.

The maximum total length of the room bus is 72 m (236 ft). The room bus uses a Cat 5 (or higher) unshielded, straight-through wired cable with eight conductors (four twisted pairs) and RJ45 connectors. The wire size (cross-sectional area) should be 22 to 26 AWG (0.34 to 0.14 mm²). When the RP controller is installed in a space that handles conditioned air or return air, the room bus cables and IP network cables frequently must be plenum-rated to meet applicable building codes. Para obtener más información, consulte Wiring . 

Aviso

LOSS OF COMMUNICATION

  • Ensure that the total length of the room bus does not exceed 72 m (236 ft).

  • Use a Cat 5 or higher unshielded twisted pair cable with eight conductors (four twisted pairs), a cross-sectional area of 22 to 26 AWG (0.34 to 0.14 mm 2 ), and a rating that meets the requirements of the target environment.

Failure to follow these instructions can result in loss of communication.

By default, the RP-V controller's RS-485 Com B port is configured and allocated for the room bus. Para obtener más información, consulte Communication Ports on RP-V-4A and -5A .

You can connect a single RP controller expansion module, or you can connect up to four devices in a daisy-chain configuration.

Aviso

When connecting devices to the RP controller room bus through a daisy-chain configuration, the room bus ports on the device are interchangeable.

The RP-V Advanced controller room bus supports up to four connected RP controller expansion modules with the following restrictions:

  • Maximum of one DALI light module

  • Maximum of one SMI blind module

  • Maximum of two Multi-sensor or Insight-Sensor devices

Each RP controller expansion module has a rotary switch, which is used to give the device a unique address on the room bus. An RP controller expansion module can be given any address in the range of 1 to 4. Configuring the address 0 means that the device enters maintenance mode and goes offline. Configuring an address in the range of 5 to 9 also means that the device goes offline. Para obtener más información, consulte RP Controller Expansion Module Room Bus Addressing . An incorrectly configured switch can cause two devices to have the same address on the room bus, which means that both devices will be offline.

Aviso

LOSS OF COMMUNICATION

Ensure that the rotary switch on the RP controller expansion module is configured to give the device a unique room bus address in the range of 1 to 4.

Failure to follow these instructions can result in loss of communication.

Tabla: Room Bus Addresses

Address

Description

0

Maintenance mode. Device offline.

1 to 4

Valid addresses for devices connected to the RP-V room bus.

5 to 9

Addresses not supported by the RP-V controller or the EcoStruxure Building Operation software. Device offline.

Aviso

Devices connected to the RP controller room bus through a daisy-chain configuration can be assigned addresses regardless of the order in which the devices appear in the daisy chain. For example, device number 1 can have the address 4, device number 2 can have the address 3, and so on.

Aviso

An RP controller expansion module can be put into different maintenance modes in which the device is either offline or online. Para obtener más información, consulte RP Controller Expansion Module Maintenance Modes .
