PROFIBUS DP
PROFIBUS DP is a 2-wire, RS485-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.
See also section
for information about the built-in bus termination resistor.
EtherCAT®
Ethernet for Control Automation Technology (EtherCAT®) is an open high performance Ethernet based fieldbus system.
Consult
Instruction manual EtherCAT® interface
(document no. 9.17.063) for more information about setting up an
EtherCAT® network.
PROFINET
The PROFINET interface is 100% Ethernet compatible and is used for data exchange between I/O controllers (PLC, etc.) and
I/O devices (slaves, field devices). PROFINET uses the proven communication model and application view of PROFIBUS DP.

Instruction manual PROFINET interface
(document no. 9.17.095) for more information about setting up a
PROFINET network.
HART
HART is a bi-directional communication protocol, owned by the FieldComm Group, for sending and receiving digital
information across the 4…20 mA analog current loops that connect the vast majority of field instruments with distributed
control systems. HART technology offers a reliable solution for plant operators who seek the benefits of digital
communication, while preserving existing analog instrumentation and plant wiring.
Characteristics:
·
Baud rate: 1200 baud
·
Easy remote access to digital functionality of instrument over analog wiring
·
Digital communication across 4…20 mA analog output
Detailed information about the HART protocol can be found on the FieldComm website:
