  PLC	stands	for	programmable	logic	controller.	A	PLC	is	a	programmable	computer	device	used	to	control	electromechanical	processes,	usually	in	an	industrial	niche.	A	PLC	is	sometimes	referred	to	as	an	industrial	computer,	a	term	that	describes	the	main	function	of	a	PLC	as	a	specialized	industrial	computing	device.	The	PLC	monitors	the	state	of	an
  input	device,	such	as	signals	from	a	light	switch,	and	makes	decisions	about	the	next	state	of	an	output	device,	such	as	turning	a	light	on	or	off.	PLCs	are	also	used	to	transfer	information	from	devices	in	factories	or	outside	to	centralized	applications	that	often	run	on	personal	computers.	PLCs	are	commonly	used	to	monitor	and	report	devices,
  diagnose	faults	in	hardware	devices	such	as	industrial	equipment	and	instruments,	and	influence	device	events.	What	is	a	relay	logic	system?	PLCs	are	descendants	of	relay	logic	systems,	which	are	control	systems	that	monitor	and	control	low-level	devices	such	as	switches,	relays,	timers,	actuators,	and	motors.	In	relay	logic	systems,	relays	perform
  logic	operations	called	relay	logic	by	activating	and	deactivating	magnetic	coils	in	electrical	circuits.	Relays	can	connect	circuits	that	use	different	currents	and	voltages,	so	historically	they	have	been	ideal	for	controlling	and	coordinating	various	industrial	automation	equipment.	The	downside	of	the	relay	logic	system	is	that	it	is	hard	wired	like	a
  switchboard	and	difficult	to	maintain	due	to	the	many	wires.	The	development	of	microcontrollers	solved	this	problem	by	allowing	relay	logic	processes	to	be	programmed,	coded	and	stored	in	a	computer.	How	does	a	PLC	work?	A	typical	PLC	is	connected	to	a	power	source	and	consists	of	a	central	processing	unit	(CPU),	chassis,	read-only	memory
  (ROM),	random	access	memory	(RAM),	input/output	(I/O)	modules,	power	supply	and	programmer	.	The	PLC	has	a	modular	design;	I/O	and	other	specialized	modules	slide	into	the	PLC	cabinet.	PLC	modules	are	sometimes	called	cards.	A	PLC	Rack	can	be	compared	to	a	car	chassis	to	which	other	components	are	connected.	The	combined	components
  in	the	PLC	cabinet	are	grouped	into	three	sections:	the	CPU,	several	I/O	modules,	and	the	power	supply.	Power	Supply	The	power	supply	converts	alternating	current	(AC)	to	direct	current	(DC).	DC	is	used	by	the	CPU	and	I/O	components.	CPU	Like	the	PC,	the	CPU	is	the	brain	of	the	PLC.	The	CPU	has	two	operating	modes:	programming	mode	and
  operating	mode.	In	programming	modeLoads	logic	in	the	form	of	programming	instructions	created	by	the	user	on	the	computer.	In	run	mode,	the	processor	executes	the	logic.	The	CPU	controls	all	PLC	operations	according	to	software	instructions	stored	in	memory.	The	tire	control	system	transfers	information	to	and	from	the	processor.	PLC	input
  modules	receive	or	perceive	data	from	input	devices	such	as	approaching	sensors	and	photovoltaic	sensors,	keyboard,	tiem,	timers,	counters,	console	lamps,	electric	motors,	temperature	and	pressure	relay.	The	concept	of	sensory	data	refers	to	the	nature	of	PLC	inputs	that	are	received	in	the	form	of	electronic	signals.	Digital	input	maps	process
  discrete	signals	such	as	on/off	signals.	The	analog	input	boards	convert	the	voltage	into	numbers	that	are	understandable	CP.	PLC	outputs	include	valves,	starters,	drives,	drives,	solenoid,	alarm,	control	relay,	printers	and	pumps.	Digital	output	cards	turn	devices	such	as	lights	on	and	off.	Analog	output	maps	convert	digital	numbers	to	stress,	for
  example,	to	control	mechanisms.	A	PLC	can	make	logical	decisions	and	perform	actions	based	on	input	data,	such	as	processing	input	data	and	sending	the	processed	data	to	an	output	device.	Input	processing	is	performed	by	the	programmer.	For	example,	a	temperature	sensor	can	monitor	the	temperature	in	a	refrigerator	and	periodically	send	this
  information	via	a	PLC	to	a	printer	in	the	plant's	operations	center.	The	programming	device	for	programming	is	usually	a	computer,	console,	or	handheld	proprietary	device.	The	input	and	output	modules	route	the	input	signals	to	the	PLC	CP	where	the	output	signals	are	created.	The	output	format	is	set	by	the	application	program	implemented	on
  the	software	device.	Memory	and	ROM	data	from	the	operating	system	and	drivers.	RAM	stores	the	state	and	details	of	the	inputs	and	outputs	and	programs	of	the	application.	Communication	input/output	modules	are	responsible	for	transmitting	information	between	the	PLC	and	communication	networks.	To	communicate	with	external	PLC	devices,
  the	recommended	standard	232	(RS-232)	is	used,	which	is	a	sequential	communication	standard.	RS-232	uses	a	binary	code	to	read	and	record	data	in	the	American	Standard	Information	Interchange	(ASCII)	format.	At	the	PLC	control	level,	data	is	exchanged	with	the	field	components	at	the	physical	level,	using	different	communication	protocols
  depending	on	the	component.	The	PLC	also	uses	various	communication	protocols	to	exchange	data	in	and	out	of	networksdevice.	Modbus	lip	is	a	serial	communication	protocol	often	used	in	industrial	communication	networks	for	long	-distance	data	transmission.	However,	serial	communication	protocols	lack	the	power	and	speed	of	Ethernet
  protocols.	Ethernet	protocols	used	by	the	PLC	include	Ethernet	TCP/IP,	Modbus	TCP/IP	and	Profinet	used	to	connect	to	the	plant	and	internet	networks.	Proprietary	protocols	can	be	adapted	to	proprietary	devices.	USB	(Universal	Serial	BUS)	protocols	are	used	to	connect	to	controllers	and	printers.	Bluetooth	may	be	used	for	wireless	devices.	The
  PLC	PLC	life	cycle	performs	four	basic	operating	functions.	First,	it	searches	all	connected	input	equipment	and	detects	their	operating	status.	Second,	it	launches	a	program	to	determine	what	to	do	with	the	input.	The	third	generates	the	realized	output.	In	the	fourth	time,	operating	cleaning	uses	internal	diagnostics.	The	PLC	with	HMI	(HMI)	uses	a
  number	of	ports	and	communication	protocols	to	connect	to	control	applications	such	as	SCADA	(Supervisor	Control	and	Data	Acquisition).	Race	operators	and	line	managers	communicate	with	PLC	in	real	time	through	HMI.	HMI	is	an	operator	control	panel	that	is	an	interface	between	a	person	and	a	PLC.	HMI	allows	the	operator	to	coordinate,
  manage	and	manage	industrial	processes	and	equipment.	Where	is	the	PLC	used?	PLCs	are	used	in	many	automated	machine	processes,	for	example	to	control	lifts	or	switch	off	and	switch	off	the	lights	in	intelligent	buildings.	PLCs	are	used	to	monitor	safety	cameras	and	automatic	warning	devices,	traffic	lights	and	industrial	processes	such	as
  cutting	glass	and	paper.	PLC	monitors	data	on	operating	hours	such	as	equipment	hours,	operating	temperature	and	statistics	of	use.	It	also	triggers	and	stops	processes	and	generates	alerts	in	the	event	of	a	machine	failure.	PLCs	are	used	to	install	products,	packaging,	movement	control,	dose	control,	diagnostics	and	testing	of	machines	and	robotic
  processes.	How	is	PLC	program?	Line	logic	is	commonly	used	for	PLC	programming,	but	other	languages	are	also	used,	such	as	a	function	block	diagram,	structured	text,	sequential	function	diagram	and	a	list	of	instructions.	The	ranking	logic	uses	hardware	graphics	schemes	of	relay	circuits	to	express	and	define	the	logical	structure	of	processes	in
  PLC	applications.	The	ladder	logic	code	looks	like	a	wiring	diagram.	The	benefits	of	PLCPLC	is,	first	of	all,	the	advantages	achieved	by	abandoning	traditional	logical	management	systems.	Compared	to	traditional	logical	management	systems,	PLC	is	easier	to	create,	install,	maintain	and	modify.	The	components	of	the	PLC	do	not	require	complex
  wiring,	since	the	management	logic	is	implemented	by	software.	Modifications	and	updates	can	be	easily	implemented	by	loading	a	new	relay	logic	program.	Adjustments	can	be	performed	remotely,	and	not	by	hand,	as	in	systems	with	relay	logic.	Logical	relay	coding	allows	you	to	quickly	develop	complex	logical	expressions.	Programming	PLC	is
  relatively	simple,	and	since	the	design	of	the	PLC	system	is	modular,	they	can	be	installed	in	various	physical	conditions	and	easily	scale	using	many	different	input	and	output	devices.	PLC	is	specialized	devices	created	for	work	in	harsh	environmental	conditions,	such	as	cold	and	strong	heat,	as	well	as	dusty	and	wet	conditions	in	factories.	The	PLC
  is	built	into	the	real	-time	operating	system,	which	has	some	auxiliary	functions,	but	does	not	require	additional	use	of	tools	such	as	antivirus	software	or	registry	cleaning	tools.	Since	the	PLC	is	based	on	a	microprocessor,	the	PLC	execution	time	is	less	than	in	control	systems	with	relay	logic,	which	have	more	mechanical	parts.	A	complex	software
  code	is	often	controlled	by	traditional	computers	than	PLC,	because	they	are	controlled	by	tasks,	not	events.	Despite	the	high	reliability,	the	PLC	systems	usually	need	external	monitors	to	display	data	in	a	form	convenient	for	the	user.	When	they	fail,	the	PLC	specialists	may	need	extensive	search	and	elimination	of	malfunctions.	In	modern	industrial
  IT,	they	need	the	correct	data.	Our	leadership	shows	how	to	introduce	comprehensive	monitoring,	which	transfers	its	elements,	OT	and	IIOT	to	your	information	panels.	Download	the	information	document	our	second	guide	gives	you	inspiration	and	ideas	for	information	panels	that	contain	OT	and	IIT	data	in	one	place.	We	will	show	you	what	truly
  convertible	industrial	information	panels	look	like!	To	download	an	information	document	on	related	concepts	of	PLC	is	often	called	a	reliable	digital	computer,	but	there	are	several	key	differences	between	them.	While	the	PC	is	required	for	the	operation	of	the	PC,	the	computer	is	not	needed	for	the	operation	of	the	PLC.	This	is	due	to	the	fact	that
  the	PLC	is	controlled	by	a	microcontroller,	and	the	computer	is	a	microprocessor.	PLCs	use	a	method	based	on	scanning	to	perform	code,	while	PCS	is	used	to	perform	code	a	method	based	on	the	event.	PLC	inputs	are	signals,	not	the	data	on	which	they	are	submitted	from	the	PC	disks.	Data	from	PLC	oftenWith	a	PC	and	is	used	to	carry	out	work
  orders,	reports	and	notifications.	The	PLC	operating	system	is	designed	for	the	execution	of	control	tasks	and,	in	contrast	to	PCs,	does	not	normally	use	antivirus	or	registration	cleaning	programs.	SPS	are	programmed	with	manufacturer's	own	languages	or	contact	plan	logic.	PCs	are	programmed	with	high	languages	such	as	Java	or	C	++.	PLCs	are
  not	immune	to	cyber	security	attacks	and	malware,	but	reported	cases	are	less	than	PCs.	The	reason	for	this	is	that	SPS	have	limited	functionality	compared	to	PCs.	Small	PLC	systems	are	usually	cheaper	to	implement	than	a	similar	PC	application	case,	but	large	PLC	systems	that	are	required	for	complex	logical	operations	can	be	expensive.	Since
  PLC	are	better	suited	for	rough	environments,	they	can	be	physically	cheaper.	What	is	the	difference	between	relay	logic	and	contact	plan	logic?	Tax	circles	in	relay	logic	systems	must	be	firmly	wired	for	each	individual	control	function.	The	relay	logic	depends	on	the	execution	of	logic	and	control	functions	based	on	diagrams	of	physical	electronic
  circuits.	Using	conductor	logic,	logic	and	control	functions	are	carried	out	using	a	programmable	microprocessor	PLC.	The	PLC	stores	the	contact	plan	logic	program	in	the	memory.	In	contrast	to	rigid	control	systems,	SPS	can	be	re	-programmed,	which	saves	time	and	money	because	expensive	wires	and	cables	do	not	have	to	be	replaced.	Only	the
  E/A	devices	in	the	PLC	have	to	be	wired.	What	is	the	difference	between	the	microcontroller	and	microprocessor?	The	terms	microcontrollers	and	microprocessor	are	sometimes	used	synonymously,	but	there	is	a	big	difference	between	the	two.	The	microprocessor	chip	has	only	one	processor.	The	microcontroller	consists	of	processor,	memory	and
  input/output	modules	(E/A),	all	of	which	are	integrated	in	a	single	chip.	The	microprocessor	cannot	work	independently	of	other	components	such	as	additional	circuits	and	memory,	E/A	modules	and	software.	The	microprocessor	is	used	when	a	lot	of	complex	processing	is	required,	for	example	for	games	and	in	laptops,	and	if	the	task	is	not	defined.
  The	microcontroller	is	used	for	repeating,	predefined	tasks,	for	example	in	electronic	devices	and	industrial	machines.	Microcontrollers	are	cheaper,	smaller	and	use	less	electricity	than	microprocessors.	Summary	SPS	enable	users	to	program	specific	tasks	for	machines	that	are	to	be	carried	out	using	the	logical	contact	plan	coding	language.	SPS
  offers	cost	-effective	automation	of	repetitive	tasks	in	industrial	niches.	You	can	also	carry	out	intelligent	tasks	such	as	automatic	order	approvaland	diagnosis	of	incorrect	equipment.	Professional	PRTG	monitoring	tools	are	based	on	complex	networks	that	often	replace	data	at	large	distances.	PRTG	is	a	network	monitoring	instrument	that	reduces
  the	downtime	of	industrial	systems	and	evaluates	the	effectiveness	of	resource	consumption.	PRTG	can	be	used	to	monitor	intellectual	border	gateways,	to	create	reports	on	metrics	of	IoT/IIOT	sensors	and	use	node-red	to	configure	data	on	devices,	online	services	and	APIs.	If	you	are	familiar	with	industrial	automation,	you	may	have	heard	of	SPS.	So
  what	is	PLC	and	why	are	you	so	important	in	the	world	of	automation?	SPS	means	a	programmable	logical	controller.	These	are	industrial	computers	used	to	manage	various	electromechanical	processes	in	production,	in	factories	or	in	other	automation	media.	SPS	differ	in	size	and	form	factor.	Some	of	them	are	small	enough	to	fit	into	their	pocket
  while	others	are	big	enough	to	install	their	own	strong	frames	to	install	them.	Some	PLCs	can	be	equipped	with	back	fields	and	functional	modules	for	different	types	of	industrial	applications.	SPS	are	widespread	in	various	industries	because	they	are	quick	and	easy	to	use	and	to	program	as	easy.	SPS	can	be	programmed	in	different	ways,	from	relay
  logic	based	on	electromechanical	relays	to	specially	adapted	basic	and	C	programming	languages,	and	these	are	just	a	few	of	them.	Nowadays,	most	of	the	PLCs	use	one	of	the	following	5	programming	languages:	stairs,	structured	text,	functional	block	diagram,	instructions	or	consistent	function	schemes.	With	SCADA	and	HMI	systems,	users	can
  display	data	from	the	production	workshop	and	users	an	interface	to	enter	the	administrative	data.	SPS	are	an	important	part	of	the	hardware	in	these	systems.	SPS	acts	as	a	physical	interface	between	devices	in	the	factory	or	in	the	production	workshop	and	in	the	Scada	or	HMI	system.	SPS	bonds,	control	and	control	of	automated	processes	such	as
  assembly	lines,	machines	or	robot	devices.	The	functions	of	the	PLC	are	divided	into	three	main	categories:	inputs,	outputs	and	CPU.	SPS	collects	data	from	the	production	floor	and	control	the	inputs	to	which	machines	and	devices	are	connected.	The	input	data	is	then	processed	by	the	CPU,	which	means	that	the	logic	is	applied	to	the	data
  depending	on	the	status	of	the	input.	The	CPU	then	carries	out	the	software	logic	created	by	the	user	and	indicates	data	or	commands	to	cars	and	devices	to	which	they	are	connected.	There	are	two	main	types	of	input	data:	dataFrom	devices	and	equipment,	as	well	as	human	participation.	The	input	data	from	sensors	and	cars	are	sent	to	the	PLC.
  The	inputs	may	turn	on	the	power	states,	for	example,	for	mechanical	switches,	buttons	and	encoders.	High/low	condition	for	things	such	as	temperature	sensors,	pressure	and	liquid	level	detectors,	or	open/closed	states	for	things	such	as	pumps	and	values.	Input	with	the	participation	of	a	person	includes	pressing	buttons,	switches,	sensors	of
  devices	such	as	keyboard,	sensory	screens,	remote	controls	or	map	reading	devices.	Exits	are	physical	actions	or	visual	results	based	on	the	logic	of	PLC	in	response	to	these	inputs.	The	physical	result	includes	the	launch	of	the	engines,	turning	on	light,	emptying	the	valve,	turning	on	the	heating	or	turning	off	the	pump.	Visual	weekend	is	sent	to
  devices	such	as	printers,	projectors,	GPS	or	monitors.	PLC	operate	in	cycles.	First,	the	PLC	determines	the	condition	of	all	input	devices	connected	to	it.	PLC	uses	the	logic	created	by	the	user,	and	then	performs	it	on	the	basis	of	input	states.	Then	the	PLC	displays	commands	to	any	output	devices	connected	to	the	PLC,	including	or	off	them.	After	all
  these	steps	are	performed,	the	PLC	performs	safety	verification,	interacting	with	internal	diagnostic	and	software	terminals	to	make	sure	that	everything	is	in	normal	working	conditions.	PLC	restarts	the	cycle	every	time	the	process	ends.	Thanks	to	the	large	number	of	available	IGNITION	drivers,	you	can	connect	the	IGNITION	to	almost	any	modern
  or	outdated	PLC.	After	installing	the	device	driver,	data	can	be	viewed	or	sent	to	PLC.	Now	that	the	PLC	data	is	available	for	the	IGNITION	tag	system,	you	can	do	much	more	with	reliable	basic	IGNIition	modules.	Create	a	comprehensive	SCADA	and	MES	system,	a	human-machine	interface	system,	alarm	and	reporting	system	or	a	solution	for	the
  entire	enterprise	that	will	allow	you	to	view	and	control	data	on	PLC	at	any	level	of	the	organization.	Traditionally,	PLC	interact	with	the	help	method.	As	a	rule,	in	local	factories	and	in	production	conditions,	this	type	of	communication	is	perfect,	because	the	communication	distances	are	short	and	mainly	wired.	Using	the	response	to	the	survey,	the
  PLC	is	constantly	exchanging	data	to	verify	data	changes.	As	the	industrial	Internet	of	things	(IIOT)	is	becoming	more	and	more	popular,	the	need	for	data	from	remote	places	is	growing.	This	means	a	larger	number	of	PLCs	and	computing	devices	on	the	boundaries	of	the	network.	Communication	with	border	devices	involves	long	distances	at
  whichNetworks	are	used	more	often.	Due	to	the	frequency	of	reacting	communication,	the	mobile	network	would	generate	extremely	high	costs.	To	solve	this	problem,	solutions	such	as	MQTT	use	an	alternative	publication	protocol	to	improve	communication	from	the	network	edges.	Although	Modern	PLC	uses	modern	communication	protocols,	the
  inherited	PLC,	which	is	still	on	the	sides	of	the	network,	requires	additional	acceleration	equipment.	Edge	Gateway,	such	as	Ingition	Edge	IIot,	from	MQTT	BROKER,	obtains	data	from	the	inherited	PLC	using	a	survey	response,	and	then	sends	data	using	the	publication	report.	This	architecture	IIOT	allows	industrial	organizations	to	create	IIOT
  solutions	in	addition	to	degraded	areas.	This	improves	the	use	of	bandwidth	and	makes	PLC	data	widely	available	throughout	the	organization.	New	products	entering	the	market	are	still	appearing	in	the	industry,	from	devices	such	as	programmable	automation	controllers	(PAC),	which	combine	PLC	functionality	with	a	higher	level	of	computer
  function	with	an	industrial	infolder.	Even	for	these	new	PLC	products,	it	is	still	popular	because	of	their	simplicity,	availability	and	utility.	Software,	such	as	ignition,	will	allow	organizations	to	maximize	their	usefulness	for	many	years.	Come	on.
