Hello everyone myself Baratwas.
0:11
In this video I will discuss briefly
0:14
about heart protocol.
0:17
In industries mostly we use hardbased
0:24
If you see here, this is one pressure
0:26
transmitter and these two are flow
0:34
Whenever we are installing a new
0:36
transmitter then we have to do the
0:41
or whenever you're doing some
0:43
troubleshooting work at the time also
0:47
you need one hot communicator
0:50
for seeing the live values inside the
0:58
You can see the configured parameters,
1:00
present measured parameters or
1:07
For that purpose, we use hot
1:12
Let's say this pressure transmitter's
1:15
designed or measure measurable range is
1:19
0 to 50 bar pressure.
1:23
But your process application
1:26
uh pressure is 0 to 10 bar range. Then
1:30
you can configure this pressure
1:32
transmitter as per your process
1:35
requirement using hot communicator.
1:41
See this is what uh this is one pressure
1:44
transmitter PT and this is the impulse
1:47
line connected to a pipeline for
1:51
measuring the pressure and this is our
1:57
Using hot communicator we can configure
2:00
the transmitter parameters
2:02
as per our uh process requirement or as
2:06
per the design basis.
2:09
And this is the back side. You can see
2:11
the hot communicator is connected to the
2:16
Mostly these are two wire instruments.
2:18
Across the two wires, you can connect
2:21
the hot communicator.
2:23
Or if you have the separate hot signal
2:26
terminals are available, you can connect
2:31
And this is our one flow transmitter FT.
2:35
This hot communicator is connected to
2:38
this flow transmitter
2:44
online parameters here on the display.
2:51
see this is our flow transmitter. We can
2:54
remove the back cover and we can connect
2:57
the part communicator
3:02
and we can see the configured
3:04
parameters. You can do the
3:08
You can set the required LRV, URV, lower
3:11
range value, upper range value. You can
3:15
do the simulation, you can do the
3:18
Okay, you can check the diagnostics. All
3:21
these things you can do from this hot
3:26
in the field. Remember
3:30
this hot communicator uses
3:33
FSK frequency shift keying technology.
3:39
By using this FSK this hot communicator
3:43
can establish communication between the
3:47
and then we can configure the required
3:53
We will use the same technology okay
4:00
for communicating between the
4:03
transmitter and the DCS system.
4:08
Let's say I will take the same case
4:10
again. This is our heartbased flow
4:13
transmitter. Right now the flow is 100 m
4:19
Previously I shown you how to use 4 to
4:22
20 milliamp based signal
4:25
for communicating or transcending this
4:27
measured flow rate from the transmitter
4:34
I will tell you another approach. We can
4:40
What is the hot signal?
4:42
FSK frequency shift keying.
4:48
We can use this hot signal for sending
4:52
this measured flow rate from the
4:55
transmitter to the DCS system. The DCS
4:59
receives this FSK signal and then
5:03
converts this signal into equivalent
5:05
measured flow rate and then the DCS
5:08
updates this flow rate on the computer
5:16
your hardware must support hard
5:21
your transmitter must support hot uh
5:24
signal transmission. At the same time
5:27
your DCS system hardware for example
5:31
analog input module, analog output
5:35
module and respective hardware must
5:39
support hard protocol signal. At the
5:42
same time you must have a software
5:45
license for using this hot signal
5:50
Then only you can fetch this data using
5:56
remember that. So this is one uh
5:59
application. I will tell you another
6:03
Let's say I will take same example.
6:05
Measured flow rate is 100 m cube per
6:09
Let's say I can use 4 to 20 millia based
6:15
for carrying this measured flow rate
6:17
measured flow rate signal from the
6:19
transmitter to the DCS system. Right.
6:25
Or I can use FSK signal
6:29
for transmitting this measured flow rate
6:31
from the transmitter to the DCS system.
6:35
Or I can use both 4 to 20 millia signal
6:40
and FSK signal simultaneously
6:44
to send this measured flow rate from the
6:48
transmitter to the DCS system.
6:53
we have option we can select uh the
6:57
required parameter. For example this
7:00
measured flow rate is one parameter.
7:03
At the same time you can select some
7:05
other parameters also
7:08
for sending this uh parameter using FSK
7:12
signal from the instrument to the
7:15
control system. then the control system
7:18
updates the value on the computer
7:22
So we have uh three cases here three
7:27
The first one is only using 4 to 20
7:32
Second one only using FSK signal. Third
7:37
one you can use both 4 to 20 milliamp
7:40
signal and FSK signal simultaneously.
7:47
for transmitting the required
7:51
In the next videos, I will show you how
7:54
to do the configuration for the FSK
7:58
signal hot signal in the Yokoga sentumvp
8:03
DCS system. Remember your hardware must
8:08
support hard protocol and your software
8:12
must have the required license. then
8:15
only you can do this projecting. Okay.
8:18
And also these signals mostly FSK
8:22
signals we use for non-critical signals
8:26
or in situations where we cannot use it
8:30
is not possible for us to use 4 to 20
8:34
millia based signals. Okay. uh and in
8:38
the end I will tell you some use cases
8:41
or applications where we use this FSK
8:46
based signals for communicating the data
8:52

8:56
with your friends and social networks.

9:04
support. I will meet you in the next
