JIN Machine Central Conveying System with PROFINET System
Introduction
PROFINET is a standard developed by PNO (PROFIBUS User
Organization) for industrial Ethernet:An internationally
established IT
standard for communications (such as the TCP/IP protocol) has great
advantages in designing, installing, and commissioning to normal
production:
Firstly, because of smart devices scattered at the front end can
perform more complex tasks, separate controllers, computing units,
etc.
are no longer needed which can save hardware investment and use
area;
FCS wiring is relatively simple, and one transmission line can be
connected to multiple devices, which greatly saves installation
costs.
Since the field control equipment often has a self-diagnostic
function and can send fault information to the control room, the
maintenance
work is reduced.
Meanwhile, Since users have a high degree of system integration
autonomy, they can choose the right manufacturer products through
flexibility.The reliability and accuracy of the overall system is
also greatly improved.
All of this helps users to reduce the cost of installation, use,
and maintenance, and ultimately achieve the goal of increasing
profits.
communication network
Field communication network for interconnection of field equipment
or field instruments used in process automation and
manufacturing automation
Equipments Interconnected
According to the actual need to use different transmission media to
connect different field equipment or field instruments
Interoperability
Users can choose different manufacturers or different types of
products according to their own needs to form the required control
loop, so that they can freely integrate FCS.
Distributed Function Block
Profinet discards the input/output unit and control station of the
DCS, and distributes the function blocks of the DCS control station
to the field instruments in a distributed manner, thus forming a
virtual control station and completely implementing decentralized
control.
Communication Line Power Supply
The communication line power supply mode allows the field
instrument to directly ingest energy from the communication
line.This method provides a low-power field instrument for
intrinsically safe environment, and is also equipped with a safety
barrier.
