In this article, we will learn how to do the configuration of analog input (transmitter) in the Yokogawa Centum VP DCS system. The DCS abbreviation is Distributed Control System.
Here we will configure a new transmitter in the Centum VP software.
You need to have some details before configuring a new transmitter in the DCS system.
First, you need the details of the Analog Input Card where you are going to connect the new transmitter.
Also, you need the location details of this analog input card in the system cabinet like FCS number, IOM details, Node number, and then AI card slot number.
You can get the details from the Nest Loading list.

The below animation will help you to understand the configuration procedure of a new flow transmitter in the Yokogawa DCS.
Follow the below steps to configure a new transmitter in DCS.
Open the System View software.
You may have one or more number of FCS (Field Control Station) in your plant.
Go to the required FCS where you want to add a new transmitter. The FCS selection depends on your plant area and the location of the new transmitter. Check your plant control system documents for more details.
Next, go to the IO module page in the selected FCS.
You have to expand the FCS folder and again expand the IOM folder.
Next, You have to go to the respective node where the AI module is installed.
You can get the details of FCS, IOM, Node location details from the Nest Loading list.
Next, select the analog input card (AAI841-H) and open it.
The location AI card details can be found in your plant nest loading list.
Next, you have to add the tag name in the respective AI module channel.
Here the tag syntax is “%%I11FT1101”
Then go to file and download.
Now go function block builder for creating the faceplate of the new tag.
Open the respective control drawing builder or choose any empty drawing.
Here, we selected a new control drawing.
Right-click on the screen and select the “Insert” option and then click on “Function Block”
Here select the “PIO” block from the drop-down menu.
Now we have to enter the same tag name in the PIO block.
In this example, our tag is %%I11FT1101
Again we need another function block for the faceplate.
Go to the menu and search for PVI block.
Now select PVI block (Input Indicator Block).
Each PVI block creates a faceplate for the tag after download.
Now we have to add a name for the PVI block.
In this example, we named the tag “11FI1101”.
This tag name is used for the faceplate.
Now both PIO and PVI blocks are created.
We need these two blocks when adding a new transmitter for monitoring purposes.
Select the wire from the top menu and connect the PIO and PVI blocks as shown in the below image.
Now we have to add the details of the new transmitter in the DCS system.
Right-click on the PVI block.
Select the “Edit Detail” option.
Now a new window will be opened and it is called “Function Block Detail Builder”.
In this window, you can find different tabs like Basic, Tag, Input, Alarm, Output, Connection, Others.
In the basic tab, you can enter your faceplate description in the “Tag Comment” field.
Next, go to the “Input” tab. Here you can define the LRV and URV of your transmitter.
Fill the Low limit value (LRV) and High limit value (URV) as shown in the below image.
In the Basic tab, you can define the required engineering unit for the new transmitter.
Then click the update button
All settings are done, close the function block detail builder window.
Click on the File menu.
Select the “Download” Option.
Next, an online download will be started for this FCS. A pop-up confirmation window will appear and press ok.

In this article, we discussed the basic settings required for the configuration of a transmitter in a DCS system.
We have many other features available like defining the alarms, displaying the transmitter value in graphics, creating trends for the new tag, etc. We will discuss these topics in upcoming articles.

very helpful material please carry on your data is very perfectively managed.
I want to get basic knowledge of Dcs system.
Good work.
please provide DCS training course
GREAT STAFF. THANK YOU SO MUCH
Hi,
How can I monitor an Analog Input signal that described abow, monitor in HIS?
hi,
thank you for this great effort and great tutorial, I was wondering where to define the alarms treshold for this transmitter as I don't see any place in PVI block for this purpose.
kind regards
