8.4 MQTT
You can activate and configure the MQTT message protocol in this menu
point. To do so, you must connect the device to an MQTT server (Broker) via
Ethernet via the ETH1 or ETH2.x interface on the CPU assembly. Note that
the device will only send messages (publish). The receive message function
is not active.
There are 2 options available for configuring the protocol:
▪ Via the IP address of the MQTT server:
– Enter the IP address as the broker address.
– It is not necessary to configure a DNS server.
▪ Via DNS server:
– Configure the DNS server in "Network settings".
– Enter the URL as the broker address.
