Now we are in Echog goa DCS software.
0:16
where is our temperature transmitter is
0:19
connected in this card. What is the tag
0:28
If you see it is connected in the eighth
0:33
You can count from the top. 1 2 3 4 5 6
0:37
7 and 8. This is the eighth channel.
0:40
Remember that. And copy the PND tag
0:43
number. And on the top if you see there
0:45
are two tabs analog data and heart
0:48
variable. Okay. Analog data is for 4 to
0:52
20 millia signal configuration. And the
0:54
second one is hot variable for hot
0:59
Okay, remember your DCS system must
1:03
support hard variables. That means you
1:05
must have valid software license and
1:09
your hardware must support hard
1:12
protocol. Then only it is possible for
1:15
you to use this configuration.
1:19
So where is our temperature transmitter
1:21
is connected in the card? It is in
1:23
eighth channel. Remember that. Go to hot
1:26
variable and here I have to enter eight.
1:30
Okay, that eight number is important.
1:33
And we have to select the required
1:34
mapping variable. Primary, secondary,
1:38
third, fourth. We have four variables.
1:41
Uh here I selected primary variable.
1:44
This depends on your transmitter
1:50
And I will call the uh tag name of the 4
1:53
to 20 millia signal 41TI1217C.
1:57
And this transmitter displaying
2:00
temperature reading 30.5°
2:03
centigrade in the DCS system. And this
2:06
is fetching data via 4 to 20 milliamp
2:09
signal. Okay, remember that.
2:13
Now I will select primary variable and I
2:16
will enter the comment like temperature
2:19
reading via hot parameter. Okay.
2:26
And then I will enter the PN ID tag
2:29
name. This is for our reference.
2:32
Let's say I will use the same tag name.
2:35
I will just add the letter H.
2:38
41 TT 1217 C H I will add the letter H
2:45
for easy identification. H means hot
2:48
variable. Okay. And the label I will use
2:52
the default uh Yogo syntax percentage
2:56
percentage I and then your tag name. In
3:05
C H. This is my label. This is very
3:08
important. We have to use the same label
3:11
in our uh function block programming. So
3:14
I am copying this tag and I'm
3:17
downloading the updated file.
3:22
For download we have to go to file and
3:24
select download and click okay. It will
3:28
download this updated program in the
3:30
card and then it will equalize in all
3:35
human interface stations. The download
3:37
is completed. Equalization is going on.
3:40
It will take some time that depends on
3:42
your number of systems. Now everything
3:47
Next I will do the uh function block
