DIGITAL MANUFACTURING - Real Time Indicator

[antoniomasseretti]

Hi Support

i've created a connection between an equipment indicator and PLC Tag.

All works fine and i can read the Value in DMC using a Production Process.

Now i've got 2 problems

1) In Equipment - Monitoring : value and trend are not visible even if the indicator is connected to the TAG

2) I'm trying to display a visual indicator (Gauge) and a time Series with indicator Value but have no idea where i can found those function

Hello Antonio,

unfortunately the dashboard designer mentioned in the blog from 2020 has been deprecated and SAC does not provide a gauge for display. Neither does the POD designer.

Kind of a workaround at least to capture the data for some indicator and get it exposed is via data collections. You can define parameters which you then post in production process when reading indicator value. However, data collections require an SFC context. But at least the values would then be available in embedded SAC if you don't want to create a custom plugin for a POD.

As far as the indicator value exposure in the Equipment application is concerned, that section of the application is part of the Asset Central application which is not being used for Digital Manufacturing. Unfortunately it was technically not feasible to hide the Asset Central features not being used by Digital Manufacturing.

As you may know, we announced deprecation of the Asset Central usage in Digital Manufacturing and instead introduce a Digital Manufacturing Asset Model. There you will not find any indicator values exposed and it will as well not create the impression of any value display.

Best regards,

Harry

Hello Antonio,

Digital Manufacturing application only leverages Equipment and Indicators for Connectivity and Automation. Indicator values of indicators mapped to tags are not persisted within the application. Hence, within the Equipment application, there are no values or trends exposed.

If you want an indicator value to be exposed in a POD today, you will need to create a custom plug-in accordingly. Latest value you can query by the Read Indicator service, persisting/caching the value or even a time series of values you will need to provide via a custom application.

With 2311, we are planning to enable a line monitor plugin to expose latest indicator values. Not as a gauge though.

Best regards, Harry

Hello Harry

thank's for your answer. This is a very bad news as the function was present in previous version od DMC as you can see from this link

https://blogs.sap.com/2020/04/20/sap-digital-manufacturing-cloud-dashboard-with-time-series-data/

Anyway if the EQUIPMENT Application doesn't exponse values or trend why in the app i have those columns visible?

and why when i create the indicator i can express and Expeted Behaviour as iif i could make a comparasion with the actual trend ?

Am i missing something?

Really thanks' for your fast answer.

I think that in product as DM the lack of features to show and indicator value and a trend releated to an Opc Ua Tag is a big problem. It's a typical requirement asked by the customer and a typical MES function expecially for process industry (ex control foundry process or food stherilization)

The possibility to link the Tag value to a Custom field in SFC TABS it's not enought because it's a spot value working only with a production in course.

I will try to implement my own extension with a cloud DB to store the values.
