Konzept
Communication Ports on RP-C Models with “-F” in the Product Name
The RP-C provides the following combination of communication ports:
Two Ethernet ports
Two USB ports
Two RS-485 ports (RJ45)
This applies to the following RP-C models with “-F” in the product name:
24 V models: RP-C-12A-F-24V, RP-C-12B-F-24V, RP-C-12C-F-24V, and RP-C-16A-F-24V
230 V models: RP-C-16A-F-230V and RP-C-16B-F-230V
Ethernet Ports
The two Ethernet ports are labeled:
Ethernet 1
Ethernet 2
The two Ethernet ports are 10/100BASE-TX (RJ45) ports.
The Ethernet interface is IEEE 802.3 compliant.
When both Ethernet ports are enabled, they function as an onboard Ethernet switch. Disabling the second Ethernet port disables the switching function. The switching function enables flexible network topologies. Für weitere Informationen siehe BACnet/IP Controller Network Topologies . The second port also provides a connection point for a laptop running the Commission mobile application.

USB Ports
The two USB ports are of different types:
USB host port
USB device port
The USB host port is a USB 2.0 type-A port, which is rated 2.5 W. The USB host port can be used for connection of Wireless Adapter - Advanced to add Zigbee TM wireless connectivity to the RP-C controller. The adapter can be used to extend the controller's point count and bring flexibility in retrofit applications. Für weitere Informationen siehe Wireless Adapter - Advanced .
The USB device port is a USB 2.0 mini-B port. The USB device port is reserved for future use.

RS-485 Ports
For the RP-C controller models RP-C-12A-F-24V, RP-C-12B-F-24V, RP-C-12C-F-24V, and RP-C-16A-F-230V, the following description applies only for hardware version 10 and later of the controller. Für weitere Informationen siehe Differences Between RP-C Hardware Versions .
The two RS-485 ports are labeled:
RS-485 Com A
RS-485 Com B
The RS-485 Com A and Com B ports are both rated 3 W (24 VDC).
The two RS-485 ports are RJ45 ports. Für weitere Informationen siehe RJ45 Pinout for the RS-485 Port(s) of the RP-C Controllers .
Each port can be configured to use one of the following three communication protocols for different types of networks:
Sensor bus
Room bus
Modbus
An RP-C can have only one of each network type.
The sensor bus is designed for communication with SpaceLogic Sensor devices. Für weitere Informationen siehe RP-C Sensor Bus .
The room bus is designed for communication with RP controller expansion modules for connected room solutions. Für weitere Informationen siehe RP-C Room Bus .
The Modbus (RTU) network can be used for communication with the KNX Modbus gateway (RP-C-EXT-KNX) and standard Modbus devices. Für weitere Informationen siehe RP-C Modbus .
One of the RS-485 ports can also be configured to support BACnet MS/TP network communication with the automation server. Für weitere Informationen siehe RP-C BACnet MS/TP Support . The other RS-485 port can then be configured to support either sensor bus, room bus, or Modbus network.

Default configurations:
Sensor bus on the RS-485 Com A port
Room bus on the RS-485 Com B port
