1. Information requests
I am searching for information regarding ConnectedCooking and OPC UA. Where can I find some?
You will find the information in your ConnectedCooking Account under
App Drawer
Administration
I checked your OPC UA documentation in ConnectedCooking but cannot find the expected details. Where can I get more?
If you need more information beyond the documentation provided, we recommend to contact cc-support@rational-online.com
Is it possible to add OPC UA-capable devices from other manufacturers to ConnectedCooking?
Currently, it is not possible to add OPC UA-capable devices from other manufacturers to ConnectedCooking.
We would like to monitor error messages via OPC UA. Have you implemented such a node?
This feature is not currently implemented.
I tried out some OPC UA nodes and received the value “-1”. What does that mean?
This is a placeholder value. The node you tested is either not implemented or only partially implemented. This should be indicated in the documentation.
How can I find the **** for the variable in the ConnectedCooking OPC UA nodes?
Go to the device page in ConnectedCooking and check the number after ".../devices/". Example: https://app.connectedcooking.com/devices/11554043/chamber/12840300 → is "11554043". Alternatively, you can use an OPC UA Client.
Can you give us an example of an OPC UA Client you are using?
You can use UA Expert from Unified Automation. Website: Unified Automation
What is the server address for the ConnectedCooking OPC UA solution?
The current server address is:
opc.tcp://app.connectedcooking.com:4840/OPCUA/ConnectedCookingYou will also find it in the ConnectedCooking documentation.
We want to use OPC UA interfaces for iCombi and iVario in a local environment. How can we achieve this?
Please contact your service partner to activate the interface on site. Then connect the cooking device via LAN cable to your local server infrastructure.
Where can I receive the code to unlock the OPC UA interface on the device?
Please contact the RSP hotline or scan the QR code using the Tech-Assist app.
What about Error Codes and Setpoints? Can we retrieve this data?
As described in our documentation, retrieving "Error Codes" and "Setpoints" is currently not possible.
What are the prerequisites and costs for using OPC UA via Cloud?
The OPC UA via Cloud solution is free of charge. A ConnectedCooking account is required, and all cooking systems must be online in ConnectedCooking.
Is there a polling limit for your OPC UA?
You can make a poll all half seconds.
2. Errors
We have subscribed to some OPC UA nodes to receive push events, but we don’t receive any updates. What can we do?
Currently, there are no "push events" implemented. Automatic updates are therefore not possible.
We are testing some OPC UA nodes on a virtual cooking device, but temperature values like "ns=4,s=CombiSteamerDevice_/CombiSteamer /ActualTemperatureChamber_0" always return 0.0. Why?
Actual temperature values can only be retrieved from real devices. They do not work on virtual devices.
We had a working OPC UA setup, but suddenly we cannot retrieve all data anymore. What could be the reason?
It is likely that changes have been made to our solution that affected the queries. All ConnectedCooking users were informed. Please check the information note in ConnectedCooking or review our updated documentation.
