The PLCnext Edge Gateway uses a DSA broker as its core communication technology. As such, it can communicate with other DSA brokers via an IP address or URL. When the PLCnext Edge Gateway is connected to another DSA broker, such as a DGLux instance, all data can be monitored on both brokers. While the DSA Broker communication will generally be used to communicate to an upstream DSA broker in the cloud, it can also point to other brokers on the local network such as other PLCnext Edge Gateway devices.
Creating a Connection
Creating a connection to a DSA broker requires the following parameters:
Name: This is a unique name given to the target "upstream" broker as it will be referenced on this device
Url: The URL of the broker to connect to. Note that the correct port number must be added to the URL in the event that communication is on ports other than 80 or 443 (http/https). The default PLCnext edge gateway ports are 8080 for http and 8463 for https.
BrokerName: The name which will be provided to the target broker of this device's name
Token: Optional authentication token if required by the upstream broker
Group: Default permissions group provided to this broker
After clicking submit, a connection between brokers should be established and displayed on the dashboard
By clicking on the DSA broker dashboard item, the page will navigate to the broker settings page and open the targeted upstream DSA broker. The connected broker's data and actions will now be available for use within the PLCnext Edge Gateway.
