Connecting RP Series Expansion Modules and Multi-sensors to RP-C

You connect RP Series expansion modules and multi-sensors to the RP-C room bus to provide the devices with power and communication from the RP-C controller.

action_close

The RP-C provides a room bus, which allows RP Series expansion modules and multi-sensors to be connected to the controller for motion detection, luminosity measurements, and control of electric lights and window blinds.

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-C 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.

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.

You can connect a single RP Series expansion module or multi-sensor to the RP-C room bus port, or you can connect up to six devices in a daisy-chain configuration.

Déclaration

When connecting devices to the RP-C room bus through a daisy-chain configuration, it does not matter if the incoming and outgoing cables are connected to one or the other room bus port on the device.

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 multi-sensors

Figure : Example of supported combination of RP Series expansion modules and multi-sensors on the RP-C room bus

Each RP Series expansion module and multi-sensor has a rotary switch, which is used to give the device a unique address on the room bus. An RP Series expansion module or multi-sensor can be given any address in the range of 1 to 6. Configuring the address 0 means that the device enters maintenance mode and goes offline. Configuring an address in the range of 7 to 9 also means that the device goes offline. Pour plus d'informations, voir RP Series 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.

Déclaration

LOSS OF COMMUNICATION

Ensure that the rotary switch on the RP Series expansion module or multi-sensor is configured to give the device a unique room bus address in the range of 1 to 6.

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

Table : Room Bus Addresses

Address

Description

0

Maintenance mode. Device offline.

1 to 6

Valid addresses supported by the EcoStruxure Building Operation software.

7 to 9

Reserved for future use. Addresses not supported by the EcoStruxure Building Operation software. Device offline.

Déclaration

Devices connected to the RP-C 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 6, device number 2 can have the address 4, and so on.

Déclaration

An RP Series expansion module and multi-sensor can be put into different maintenance modes in which the device is either offline or online. Pour plus d'informations, voir RP Series Expansion Module and Multi-sensor Maintenance Modes .

Déclaration

LOSS OF COMMUNICATION

Locate the room bus wiring away from external electromagnetic noise sources such as high voltage cables and Variable Frequency Drives (VFDs) for AC motors.

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

Déclaration

EQUIPMENT DAMAGE

Do not connect an Ethernet cable from the controller's room bus port directly to an external Ethernet switch or router.

Failure to follow these instructions can result in equipment damage.

To connect RP Series expansion modules and multi-sensors to RP-C

  1. Install the RP Series expansion module or multi-sensor and connect a Cat 5 (or higher) unshielded, straight-through wired cable with eight conductors (four twisted pairs) to one of the two RJ45 receptacles on the module or multi-sensor. Use a cable with the wire size (cross-sectional area) 22 to 26 AWG (0.34 to 0.14 mm²).

  2. Connect the other end of the cable to the Room Bus port on the RP-C controller.

  3. When an additional RP Series expansion module or multi-sensor is needed, install the device and connect the other end of the cable to the unused RJ45 receptacle on the previous module or multi-sensor.

  4. Repeat step 3 to install additional devices up to the maximum number of six devices of the supported combination of RP Series expansion modules and multi-sensors. Pour plus d'informations, voir RP-C Room Bus .

  5. Ensure that the rotary switch on each RP Series expansion module and multi-sensor is configured to give the device a unique room bus address in the range of 1 to 6.
