Advancements in PLC
What is a PLC?
Programmable Logic Controllers (PLC) continue to emerge as
new technologies are added to their capabilities. The PLC started out as a
substitute for transferring banks. Gradually, various deceptive and logical
deceptive tasks were added. Today they are the brain of many automated systems,
processes and specialized equipment. PLCs now integrate smaller cases, faster
CPUs, networks and a variety of internet technologies.
You can think of PLC technology
as a small industrial computer that is very specialized in reliability in the
factory environment. At its core, PLC monitors digital and analog sensors and
switches (inputs), learns its control system, performs mathematical
calculations and consequently controls various hardware (output) such as
valves, lights, relays, servo motors , etc. time frame in milliseconds.
Latest trends in
industrial automation
Recent industry
automation trends include increased data usage, increased use of PLCs, PACs,
and increased cloud-based orientation control and data acquisition systems
(SCADA). These approaches will have an impact on the industrial automation
control market, according to the report.
The report also predicts that
these measures will also result in a combined eight percent growth rate (CAGR)
in the Asia-Pacific region, but trends can be seen globally. The automotive
industry is gearing up for the future of unparalleled production driven by high
energy efficiency, better design and operator visibility, and robust safety
standards.
Scope of plc
programming
PLCs are constantly
growing and emerging to be the best choice for automated industrial
applications. The range of plc systems is growing rapidly due to greater
flexibility and simplicity, flexibility, additional memory, smaller sizes,
high-speed Ethernet (gigabit) and built-in wireless features. PLCs benefit from
USB technology and make it easier than ever to connect to the Internet, system,
and monitor your control systems. The PLC program will appear, and with the
availability of micro and micro USB connectors, you can expect to see this
option in other smaller PLCs. In the future, PLCs will continue to evolve while
updating technological advances in communications, hardware, and software.
Future scope of industrial automation
The future scope of industrial
dynamics could be good enough as all technologies are involved in automation
strategies. It is the use of various control devices such as PCs, DCs, and PLCs
to control various industry operations without significant human intervention
and provide automatic control operation. In industry, there will be a
collection of technologies used to determine the performance you want or
output, making automation systems the most important industry. On the other
hand, industrial automation includes the use of advanced control techniques
such as cascade controls, hardware control tools and other flexible control
sensors etc.
Latest PLC
technology
The latest PLC
technology helps monitor and control distributed server / multi-user
applications. It also provides a complete and accurate picture of performance,
meeting the needs of many stakeholders including retention, engineering,
operations, and information technology (IT) technologies. Reliable and robust
performance can be achieved using the latest PLC technology. These technologies
allow you to take advantage of visualization, navigate with other new
technologies, meet a variety of ongoing challenges, different applications and
bring significant visibility when you need it.
New technologies in PLC development
1. Two-finger touchscreen
New touch screen
function panels have the ability to see two fingers.
Although mobile
phones have had this feature for several years, this function has recently been
introduced into the industry, bringing with it major benefits:
• Allows you to zoom in on screens, especially with pictures.
• ‘Shift’ functions with two key commands
- ‘Ctrl + one key’,
etc.
• Increases the safety of some activities.
2. Direct connectivity with SQL databases
Today the entire
computer software industry operates on a website. However, some years ago this
transfer of data to the PLC was not automatic, so an additional computer with
SCADA program had to be used to connect to the database.
• New PLCs include integration, especially with SQL (Structured Query Language).
• It is very easy to set up, so it is not
necessary to ask for IT
staff support to set up.
• They allow us to have the information we
are most
interested in on a daily basis and to improve the process.
• Save money and time on product development.
3. Robot control via PLCs
The modern
components of these PLCs (chips, integrated circuits) give them extraordinary
processing power.
• There are currently medium-sized PLC
machines available
that can handle up to 32 axes, which can
be translated into
control of five robots with six axes each.
• There are two ethernet ports to advance
the ring type
topology.
• Many screens already include a web
connection, so with a
simple
configuration we can access the robot operating
system console on any mobile device.
4. Operator safety
They comply with
SIL2 and SIL3 (Safety Integrity Standards) with machine safety requests.
This makes it
possible to ensure that the risks posed by machinery to humans, the environment
and equipment are reduced to the lowest possible level.
Four or five years
ago very few companies had this certificate; however, today it is almost the
same for PLCs.
• Reduce the risk to the employee's daily operations.
• SIL-certified equipment has unused
(duplicate) CPUs that
separate dangerous functions from normal.
• There are inputs and outputs that can
handle inadequate
channels.
• Planning for guaranteed activities in
emergency closures,
safety curtains, etc.
• Strong encryption protection that can
help prevent
potential burglary.
5.‘Time Traveler’
This tells us what was going on in the system administrator
when an error occurred in the process. This may be due to the integrated video
camera with internal recording of actions in PLC.
• Allows the
user to 'go back in time' to reproduce the
recording of a
failed process and to see if the PLC was on
time.
• Make error
analysis easier and help find solutions faster.
Conclusion
The
future of the PLC in industrial automation has been on the rise since 1947 and
most of the switching industries are using PLCs and control systems to reduce
manual labor and improve accuracy and efficiency. PLCs are very popular because
of their accuracy.
