Looking for advice on the best way to duplicate a PI image for a mass production machine (small numbers)
On the PI (Raspberry Pi CM5) I run ignition and codesys. I want to create a master image for quick duplication. I tried setting one up, naming the gateway master image, re-imaged a new pi, changed the gateway name But when I connect it to the main ignition server for MQTT and EAM they over write each other. I assume as the serial or ID is the same for each image.
So now I’m thinking I just unzip necessary edge files but not actually run the gateway. Create a image then on each new instance run the files. That way each one will have a unique serial / ID.
Or am I over thinking this and there is a easier way ?
Are you changing the MAC address to the correct values for each PI? Most images overwrite the MAC with their own values, this is used for a lot of machine identification.
Codesys has a fully compiled soft PLC with realtime kernel built for Raspberry Pi.
This is a very common pairing, especially on the likes of RevolutionPi hardware which provides UL listed hardware with real IO.
For MQTT, assuming sparkplugB, you have to change the Node & Group to a unique combo. If not SparkplugB, you need to change the topic path to a unique path. Otherwise, yes, they are going to overwrite each other.
Not positive, but I think your issue is the uuid. Look for the file .uuid in the Ignition/data folder. If you are duplicating that file then you’ll have issues adding both to the gateway network.
