  Write	the	ladder	logic	for	a	simple	motor	and	portable	lamp	specifying	Allen	Bradley's	PLC	programming	software.	Design	a	simple	PLC	ladder	logic	to	control	the	conveyor	motor	on	and	off	using	switches	and	indicate	status	with	lamps.	Let's	look	for	example	PLC	programming.	Write	a	simple	logic	program	for	various	switches.	Symbolic
  representations	of	contacts	and	coils	are	the	basic	symbols	of	any	lathe	ladder	instruction	set	used	in	PLC	programming.	A	complete	PLC	ladder	program	consists	of	several	levels,	each	of	which	controls	an	output	interface	connected	to	the	starting	field	device.	May	18,	2020	If	you're	looking	to	get	a	handle	on	industrial	automation	and	have	been
  looking	for	some	basic	PLC	training	but	aren't	sure	where	to	start,	the	Break	PLC	blog	series	was	written	for	you!	After	reading	this	four-part	PLC	training	series,	you	should	be	able	to	identify	the	basic	elements	of	a	PLC	system	and	have	a	basic	understanding	of	the	purpose	and	functions	of	a	PLC	(I	PAC).	After	completing	this	series,	you	should	be
  ready	to	learn	PLC	programming.	If	you	have	any	questions	about	this	content,	please	comment	on	the	post.	So,	without	further	ado,	let's	get	into	our	introduction	to	PLC!	Starning	Series	PLC	Training	Series	Programmable	Logic	Controllers	(PLCs)	are	small	industrial	computers	with	modular	components	designed	to	automate	custom	control
  processes.	PLCs	are	often	used	in	industrial	factories	and	plants	to	control	motors,	pumps,	lights,	fans,	switches,	and	other	machines.	To	better	understand	the	purpose	of	the	PLC,	let's	look	at	a	brief	history	of	the	PLC.	The	history	of	industrial	automation	began	long	before	the	PLC.	In	the	early	to	mid-20th	century,	automation	typically	occurred
  through	complex	electromechanical	relay	circuits.	However,	the	number	of	relays,	wires	and	space	required	to	build	even	a	simple	onewas	problematic.	Thousands	of	relays	may	be	needed	to	automate	a	simple	production	process!	What	if	you	need	to	change	something	in	the	logic?	Oh	no!	NOTE:	At	a	basic	level,	electromechanical	relays	operate	by
  magnetically	opening	or	closing	electrical	contacts	when	the	relay	coil	is	energized.	These	are	very	useful	devices	and	still	play	an	important	role	in	industrial	automation	(a	more	in-depth	lesson	on	electromechanical	relays	is	in	this	post).	In	1968,	the	first	programmable	logic	controller	appeared	to	replace	complex	relay	circuits	in	industrial	plants.
  The	PLC	was	designed	to	be	easily	programmed	by	plant	engineers	and	technicians	who	were	already	familiar	with	relay	logic	and	control	schemes.	From	the	beginning,	PLCs	were	programmable	using	ladder	logic,	which	was	designed	to	mimic	control	circuit	diagrams.	Ladder	diagrams	look	like	control	circuits	where	current	flows	from	left	to	right
  through	closed	contacts	to	energize	the	relay	coil.	Ladder	Logic	Example	As	you	can	see,	Ladder	Logic	looks	like	simple	control	circuit	diagrams	where	input	sources	such	as	switches,	buttons,	proximity	sensors,	etc.	are	shown	on	the	left	and	output	sources	on	the	right.	The	ability	to	program	complex,	automated	processes	through	an	intuitive
  interface	such	as	ladder	logic	has	made	it	easier	for	many	in	the	industry	to	move	from	relay	logic	to	PLCs.	Although	the	first	PLCs	had	very	limited	memory	and	speed,	they	improved	rapidly	over	the	years.	The	presence	of	PLCs	has	helped	simplify	the	design	and	implementation	of	industrial	automation.	You	can	read	more	about	the	history	of	PLCs
  in	this	great	short	article	from	AutomationDirect	here.	How	do	PLCs	work?	PLCs	can	be	described	as	small	industrial	computers	with	modular	components	designed	to	automate	control	processes.	PLC	controllers	are	the	control	units	of	almost	all	modern	industrial	automation.	The	PLC	contains	many	components,	but	most	of	themCan	be	divided	into
  three	categories:	input	output	processor	(CPU)	is	a	sophisticated	and	powerful	computer.	However,	we	can	describe	the	PLC	function	in	a	simplified	way.	A	PLC	takes	inputs,	creates	logic	at	the	CPU	inputs,	and	then	turns	an	output	on	or	off	based	on	that	logic.	The	details	will	be	discussed	later,	but	for	now,	think	about	this:	CPU	Monitoring	input
  state	(eg	switch,	proximity	sensor,	valve	40%	open,	etc.)	Inputs	CPU	drives	the	output	output.	Logic	(e.g.	turn	off	the	engine,	open	the	valve,	etc.).	Take	a	look	at	the	block	below	to	visually	see	the	above	steps.	The	PLC	Feature	FlowChart	will	use	a	familiar	example	to	illustrate	how	a	PLC	works.	Your	dishwasher.	Many	dishwashers	have
  microprocessors	that	work	similar	to	a	PLC.	A	dishwasher	has	inputs,	outputs	and	of	course	a	central	processor.	Some	dishwasher	control	entrances	would	have	a	button,	water	sensors	and	door	switch	on	the	front.	Some	of	the	dishwashers	would	be	water	valves,	heating	elements	and	pumps.	Now	let's	think	about	how	the	dishwasher	uses	these
  different	ingredients.	Note.	Remember	that	the	CPU	is	the	dishwasher's	processor	that	is	programmed	to	make	all	the	following	decisions.	It	is	like	a	PLC	processor	(CPU)	that	makes	logical	decisions	based	on	input	status.	User	presses	cycle	mode	button	(input)	User	presses	Start	button	(input	determined)	CPU	checks	if	door	is	closed	(input
  determined)	Refill	valve	opens	and	dishwasher	begins	to	fill	water	processor	(output	activated).	Until	the	appropriate	water	level	is	reached	(input	determined)	the	valve	closes	and	the	water	stop	(output	activated/deactivated)	is	on	(output	activated)	The	CPU	waits	for	the	correct	dispenser	(input	determined)	(output	activated)	The	water	pump	turns

Enabled/Disabled)
  digital	and	similar	E/A	inputs	and	outputs	are	often	abbreviated	with	the	term	I/O.	In	the	dishwasher	example	above,	we	treated	each	input	and	output	as	a	discrete	or	digital	signal.	Non-safety	alarms	are	alarms	that	can	only	be	turned	on	or	off.	These	are	the	simplest	and	most	common	types	of	I/O.	In	our	example,	we	did	not	use	analog	I/O.	While	a
  similar	E/A	could	be	used	in	a	dishwasher	control	system,	I	just	wanted	to	keep	this	example.	With	analog	signals,	instead	of	one/off	or	open/close	options,	you	can	have	0	-	100%,	4-20mA,	0	-	100	degrees	Celsius,	or	whatever	you	measure	as	input	or	control	as	result.	We	will	deal	with	this	in	more	detail	in	part	3	of	the	free	PLC	tutorial	series	for
  beginners.	PLC	or	PAC?	You	may	have	heard	of	the	Programmable	Automation	Controller	(PAC).	The	term	was2001	shaped	by	the	research	company	ARC	distinguishes	the	original	PLC	from	newer,	stronger	and	more	flexible	control	elements	that	appeared	on	the	market.	There	is	a	misunderstanding	as	to	the	differences	in	the	definition	between
  PAC	and	PLC,	and	dates	are	often	used	synonymously	in	the	industry.	I	often	use	terms	synonymously.	This	article	here	with	Control	Engineering	can	help	understand	the	differences	between	PLC	and	PACS.	In	my	opinion,	PAC	is	always	a	better	choice,	unless	the	system	is	very	simple	and	minimizing	project	costs	is	crucial.	Modern	user	interface,
  additional	performance	and	memory	of	most	PACs	make	most	SPENs	clearly	better.	Allen-Bradley,	one	of	the	current	market	leaders	in	industrial	automation,	shows	its	PLC	lines	such	as	PLC-5,	and	instead	focuses	on	PAC	lines	such	as	Contrologix	and	Compactlogix.	Personally,	I	consider	it	a	great	action.	In	addition	to	many	other	PAC	advantages,
  user-friendly	Rockwells	RSLOGIX	5000/Studio	5000	Logix	Designer	(programming	software	for	Contrologix/Compactlogix-PAC)	exceeds	older	RSLOGIX	5/500	software	for	SPS	5	and	SLC500).	Experience	from	both	PLC	and	PACS	is	important	for	everyone	who	is	interested	in	working	with	industrial	automation.	However,	PAC	is	the	future	and	there
  you	spend	most	of	your	time	as	an	industrial	automation	engineer/technician.	The	conclusion	now	you	should	better	understand	what	SP	is,	your	story	and	how	you	work.
