Hello.
In this video we are going to learn high speed comparative set reset and Zone comparative instructions
or commands for precise positioning or material measurement.
You want your system to stand right where you want it in applications such as product cutting like a
flying shear or measuring distance interrupt function can be called P. Diddy's eighty eight C command
when the measurement set value is reached Channel Zero.
We are going to use for all examples in this video and an example in here.
If the current value.
Let's take a look first our project or the program in the first second and 1000 to outsider label it
is going to set M1264, 65 and 73 are auxiliary relay
according to our channel.
These are all special auxiliary less than we need to set these bits for Channel 0.
So we will use Channel Zero.
In this example in here.
Always on contact in order for our counter and our counter to handle fifty one is counting up.
And this is our maximum value twelve thousand five hundred.
Doesn't matter for a moment in here.
The usage of our instruction so high speed comparative set command instruction in here and our counter
is going to count the policies and then all counter read the one thousand pass value.
It is going to activate or set immediately a zero command for comparing to reset command high speed
comparative reset come on we will use that same channel.
Is this an example.
And 1002 is going to set same auxiliary relays in the first second for plc for scan and for example counter
251 counter.
Same it's going to count up and then all counter read 1100 pulse value or possibly one wants to read
this value or detect this pause immediately it is going to disable and zero bit in the command.
And this is the H S C R.
This is our campaign to reset command usage for the zone comp. command in here.
This site is similar for the Channel Zero and this is our counter 251 is similar.
Like before and now we will take a look to these instruction D H S as so in here.
If our counter values see two hundred and fifty one is lower than K two thousand or decimal two thousand
velour m 0 is going to be high.
If our value counter value between 2000 and 2040 m 1 is going to high and if all value is bigger than
or greater than 2400.
That moment aim to bit is going too high.
So this is according to hear what you put in here and this is not a standard comparison command when
the pulses is is reached two thousand.
That moment it will activating or giving a reaction immediately.
These are for the special purpose.
plc commands.
If we are working with very sensitive very high sensitive jobs or plc projects then you need to use
these commands d h c a g s t s high speed comparative set command the H S C are high speed comparative
reset command and the H S ze high speeds on comparative command.
So for this video I am finished here.
See you in the next video.
