ET-2200 Series Ethernet I/O Modules

4.13 MQTT-DO

The DO page is where you can set a full Topic Name, which is a combination of the Sub Topic Name
and the Main Topic name. The Publish and Subscribe functions for each DO channel can be
enabled or disabled on this page. You can use either a single-channel (DO0...) or multiple channels
(ALL) to process the Topic operations. Multi-channel operation is recommended because it can
help reduce the amount of network traffic.
In single-channel operation, the values 0 and 1 correspond to the OFF and ON settings,
respectively. In multi-channel operation, a hexadecimal value represents the settings for all
channels. For example, the value 0xFF00 indicates that channels 0 to 7 are OFF and channels 8 to
15 are ON. Please turn off unused Topics to reduce unnecessary processing, as it will affect
operational efficiency.
