Modbus

Modbus is a 3-wire, RS-485-based fieldbus communication system for parameter value exchange. In this system each

instrument/device is equipped with a micro-controller for its own dedicated task. The instrument behaves as a slave, which

means all communication (instructions and readout) is initiated by a master device on the Modbus system.

Characteristics:

Baud rate selectable between 9600 and 256000 Baud (default: 19200 Baud)

+15…24 Vdc supply voltage

Connection of up to 247 instruments on a single bus

Supports RTU and ASCII protocols

Consult

Instruction manual Modbus interface

(document no. 9.17.035) for more information about setting up a

Modbus network.

Detailed information about Modbus can be found at

www.modbus.org/

or any website of the (local) Modbus

organization of your country (if available).

2.6.3.3

PROFIBUS DP

PROFIBUS DP is a 2-wire, RS-485-based industrial data communication standard (fieldbus) which allows automation

components (e.g. sensors, actuators and controllers) to exchange information.

Consult

Instruction manual PROFIBUS DP interface

(document no. 9.17.025) for more information about setting up a

PROFIBUS DP network.

2.6.3.4

DeviceNet™

The DeviceNet™ interface offers a direct connection to a DeviceNet™ network, according to the mass flow controller profile

specified by the ODVA. The Bronkhorst® DeviceNet™ instrument is a Group 2 Only Server device whose messages comply

with the Controlled Area Network (CAN) 2.0A standard and with the DeviceNet™ protocol.
