Outputting Data and Controlling Operation through PROFINET
FQ2-S3 FQ2-S4
Overview of PROFINET
PROFINET is a network for industrial use that applies industrial Ethernet (100 Mbps, Full duplex) to PROFIBUS DP.
PROFINET is an open standard that is managed by PI (PROFIBUS and PROFINET International), and is used
in a variety of types of industrial equipment. Because PROFINET uses standard Ethernet technology, a variety
of general purpose Ethernet devices can be included in the network.
This section provides an overview of PROFINET that is necessary in order to use the FQ2 with PROFINET.
For the detailed specifications of PROFINET, refer to literature from IEC61158, IEC61784 and PI.
Types of PROFINET
PROFINET has two types of standards: PROFINET IO and PROFINET CBA.
• PROFINET CBA
Inter-device communication using components. Mainly used between controllers.
•PROFINET IO
Control by I/O data between a controller and devices.
The FQ2 supports PROFINET IO.
PROFINET IO uses the same device model as PROFINET DP. The information of each device is described in
a GSD (General Station Description) file based on XML (Extensible Markup Language).
