We are working on a control system with distributed logic on several units where all units have there own "brain"(plc) with an opc ua server. All units are instances of standard types that we have defined.
For this system we want a visualization unit that can utilize the power of opc ua information modeling. We want to:
- Create graphic templates that can display instances of our defined types
- Browse opc ua network and display recognized units in the predefined templates (faceplate)
- Display/handle alarms from the servers without having to define the alarms in the HMI. The alarms exist in the units.
Similar functionality is mentioned in almost every text that is written about Opc ua and information modeling. Yet, a simple tool for creating faceplates that can be pointed to instances of opc ua types have been surprisingly hard to find. Why is that? And does anyone have any tips on HMI/Scada tools I could have a closer look at?
There are other products from other vendors who may post a followup but here is one example to look at:
Thank you very much Randy Armstrong!
I have looked at Atvise earlier, but it might have been the Atvise Scada, that seems to have a bit to much overhead for our needs. I will look closer at Builder
Basically we are looking to add the HMI as a pure stateless graphical layer on top our Opc UA structure. All logic state etc. will be stored in the units. Something like UaExpert with customized graphics..
I am still interested in more suggestions 🙂
