Page 5: Introduction
PRODUCT MANUAL - BARIX R6 - V01.03 - 07/20/2005 Introduction The BARIX R6 is a relay extension unit for the Barionet adding 6 relays capable of switching 10 Amps at up to 250 VAC. Since the standard Modbus/RTU protocol is used, the BARIX R6 can also be employed in other applications as a Modbus controll- able relay unit. -
Page 6: Hardware
RS-485 and power connections, one on the left and one on the right side, facilitate easy daisy chaining of multiple devices. The BARIX R6 is equipped with a universal power input and Power supply accepts both AC and DC voltage. The AC supply range is12 to 24 requirements Volts and 9 to 30 Volts when powered by a DC power supply. -
Page 7: Led Indicators
PRODUCT MANUAL - BARIX R6 - V01.03 - 07/20/2005 The host interface of the BARIX R6 is an RS-485 interface, which RS-485 is connectible via extension connectors as well as via screw terminals. Besides “A” and “B” signals for the differential, bidirectional bus signal, a third connection is available, commonly referred to as “reference ground”. -

PRODUCT MANUAL - BARIX R6 - V01.03 - 07/20/2005 Connectors Connector Pin out overview All relays provide separate NO/NC capability, and can switch up J5,J6,J7 Pin out to 10 Amps at max. 250VAC. An indicator LED per relay is (Relays) activated together with the relay. -

Signal ground of the Barionet R6 via a 100 Ohm resistor and can be used for grounding applications. “Signal GND” is the system ground of the R6 – which is NOT identical to the supply “VSS” pin – and is used for measuring purposes only. -
Page 10: Protocol Support
The BARIX R6 also supports some special, Barix proprietary Special Commands commands which have been implemented to ease configuration and facilitate the use of the R6 in conjunction with non-Modbus systems. These commands are further described in this manual and are:... -
Page 11: Exceptions
All other devices with Modbus addresses 1..4 and 9..255 are not affected by the command. The command code 69 (hex 45) is used to set an R6 device which Command 69 is connected to the bus and which address is unknown (but serial parameters are correct) or which is forced to default settings with the default jumper. -
Page 12: Command 70
Command 70 without a return acknowledgment. The command uses the exact syntax of the 05 (set coil) command, but the R6 does not send an answer and is immediately ready to receive the next message. The command should be send addressed to the device address and NOT as a broadcast, otherwise all R6 units on the bus will react to it. -
Page 13: Configuration
PRODUCT MANUAL - BARIX R6 - V01.03 - 07/20/2005 Configuration The BARIX R6 is configured via the RS-485 interface using Default Parameters standard Modbus commands. If the address of the device is not known, it can be temporarily set to default parameters by setting a jumper in the device. No reset is necessary. -

PRODUCT MANUAL - BARIX R6 - V01.03 - 07/20/2005 Connecting external loads The BARIX R6 features 6 relays capable of switching resistive loads (lamps, heater) 10 Amps at up to 250 VAC. Cautious calculations should be performed when switching inductive loads like motors or transformers as used in low voltage... -

PRODUCT MANUAL - BARIX R6 - V01.03 - 07/20/2005 Modbus Register Map The BARIX R6 supports all 64k address locations in the Modbus address maps, however, unimplemented locations generate an exception when read or written. The Modbus address range is divided in multiple address maps, all 65535 registers in size. - Page 17 The information is accessible using standard reads from addresses 257..264. Register 257: set fixed to “0xB1” (stands for Barionet R6) Register 258: software version, 2 at the time of printing. Register 259: first part of the serial number (byte) Register 260: second part of the serial number (byte) Register 261..264 are reserved for future use by Barix...
