so today this video is going to
introduce you the function of the text
block as well as the LCD backlighting
function in ladder logic so let's get a
new project started here still we select
our favorite device as our strength v10
NPT select ladder logic as our
programming language click on s to go
into the program interface on the bottom
section you will find this button here
with this icon this is the text blog
function the text block can be used as a
coil in the program we can add up to 16
text blocks in one ladder logic program
there are two types of the co u here and
they will call you and a reset call you
so let's drag it here drag another
reason over here so let's see how the
text block codes are described double
click on the contacts and then click on
question mark to bring up the online
help file tax blog topic as you can see
here there are detailed description
about this functionality I'm going to go
into cable out a simple program as a
demonstration to see how this work
exactly next to the text block here you
will find the LCD backlighting function
here we can drag the function block on
the coil column double click on it to
bring up the description about this
function here which means that if you
gave this block it costs in the high
signal the back line of your front LCD
on the smart relay will light up and if
we do energize it that light goes off so
let's build up a simple program here to
demonstrate the function for both blocks
here I want to use a timer and then
trigger a counter the upcoming counters
one counter reaches a specific preset
value it will trigger my text block to
show some letters here on the front LCD
also when the timer are say when the
text block shows up I wanted the front
LCD to light up here I need to use the
content of the timer as well then I need
to have a input to reset the counter
ourselves reset the text block conduct
it okay and as we can see that the power
and consistency monitor is to give us
our you read a warning here let's click
on it to see what's - hello so timeout
value zero preserve counter 0 yes that's
true we haven't set the timer that we
haven't decided the text block across
the counter yet so now September 1st
here I want to use that symmetrical
flashing function I want to do every
single half second I want this into
account so what I did here is actually
using that flasher timer to help me to
trigger the counter so I don't have to
manually push really close the compact
for 20 or 30 times until the counter
reaches to preset value let's see
until the value reaches turday
that's too long so until the batter
reaches 20 I want to my counter to
trigger the text block so as you can see
here here it is the text block double
click hide to go into the configuration
window here on the text block we can see
two windows here the first window is the
resource of this text block it can show
the information listed here either
show the date call the time the
calibration information for this program
and also it can show you the preset and
current value for this timer as well as
the preset and current value for this
counter so how to add in to the text
block so this information can appear on
your front LCD the second window is
corresponding to your front LCD on the
smart relay this is a 4 by 18 screen so
4 by 18 screen simply click on any of
the position then there will be a cursor
flashing here this will be the starting
point for either the letter or the
numbers or the live values you are going
to show on the front LCD for example for
the first row I want to show the value
was it car and value of my timer so I
click on the first position here and
then double-click on the column and of
the timer as we can see there is a
formula showing up here and then I want
to have a no-stress timer 1
and then for the second drill for
example I want to show the current value
of my counter that I will see counter 1
c1 for the third row I want to show the
current time here also I want to type in
some customized learners so the ammo for
text and then ok to accept the change so
now we can see the program consistency
monitor is in blue which means now the
program's arrow free so let's run a
simulation here okay so this is the
front handle simulator for your smart
ready screen okay so that's now round
the program so this program works this
way so if I close
it's great input number one this is a
symmetric flasher little flash very fast
and a trigger this app can encounter as
we can see the preset of an idea for the
timer an autonomous listen here the
timer will turn the timer contact on
every half second preset value for the
upcoming counter is 20 so if the value
reaches 24 my counter then the counter
contact will gave a constant on signal
to my tax block and then something
should appear here on front LCD also the
LCD backlight should light up on from
the LCD if I close this great input I to
here it will clear my counter and then
also
you raise everything showing up on the
front LCD does he how it works here
close it so you can see it's counting
really fast right now counter is
increasing so if this car in the matter
of the counter reaches 20 the text block
of your trigger and it's something will
show up here no we can see it is showing
whatever you put here
for the first row is the current value
of the timer second row is a car in the
middle of the counter the third row is
Cardinal time for Sirois you stood
customized text we put in there now I
want to stop this and clear every scene
on the front LCD I just reset to my
counter and now we can see the
customized attacks on the front LCD is
cleared out and destroying the default
window
