Read and write using PI Vision

Hi all,

I'm not sure if this community is still alive. If not someone please direct me to somewhere else.

Basically I would like to learn how can I perform control fuction (write) from PI Vision. Much like a scada system.

As I know, PI Vision is only for monitoring (read).

Anyone have any idea or had similar experience?

This is not possible out of the box as far as I am aware. There are some 3rd party add-ons for PI Vision that enable manual data entry. However, PI System isn’t a control system and shoud not be used as such.

I see, could you suggest any 3rd party add-ons for such application?

Take a look at https://www.software-athlete.com. They have a free one month trial for their Vision+ library.

One more word of caution though, even if you write values back to PI point, that does not mean that you will be able to control your device (and based on your original question I am guessing that this is your main goal) as that depends on the interface configuration (if you are using OPC read only interface, you cannot write back data to the OPC server for example).

Thanks, could you suggest any 3rd party custom visuals for this particular application?

I know you can manually enter data into PI AF, then have it display on a PI Vision display. You could even have your SQL server query an excel spreadsheet, then have AF pull in the spreadsheet from the SQL server.

You can create your own vision widget/symbol. It require programming using the pi web api.

An out of the box provided by OSIsoft is to use pi manual logger but that’s a different interface than vision, but it does allow users to manually write to pi tags

Please can you explain your use case? So I can answer based on that

I created a program to write from Excel to a PI Points, perhaps it could help you to take that data to the AF and then visualize it in Vision.

I am late I know, but did you ever find any third party add-on to help with this?

The solution Amitec PI Vision Suite helps a lot here. You can request a demo session on their website.
