3.6 Other field bus configurations
The following field buses are optionally available for the EL-FLOW Prestige instruments. For all mentioned field bus systems the EL-
FLOW Prestige instruments serve as slaves on the master/slave bus system. There is no mutual communication between slaves,
only between master and slave.
PROFIBUS DP
PROFIBUS DP is a 2-wire, RS485-based industrial data communication standard (field bus) which allows automation components
(like sensors, actuators and controllers) to exchange information. For more information regarding the PROFIBUS DP interface refer
to document 9.17.025.
DeviceNet TM
The DeviceNet TM interface offers direct connection to a DeviceNet TM network according to the Mass Flow Controller Profile
specified by the ODVA. The Bronkhorst DeviceNet TM instrument is a Group 2 Only Server device which messages comply with the
Controlled Area Network (CAN) 2.0A standard and with the DeviceNet TM protocol. See document 9.17.026 for more information
about the DeviceNet TM interface.
EtherCAT®
Ethernet for Control Automation Technology (EtherCAT ® ) is an open high performance Ethernet-based field bus
system. The EtherCAT® interface is described in more detail in document 9.17.063.
PROFINET
The PROFINET interface is 100% Ethernet-compatible and is used for data exchange between IO controllers (PLC, etc.)
and IO devices (slaves, field devices). PROFINET uses the proven communication model and application view of
PROFIBUS DP. Refer to document 9.17.095 for more information.
