MQTT-DI
The DI page is where you can set the Topic Name, which is a combination of the Sub Topic Name
and the Main Topic name. The Publish function for each DI channel can also be either enabled or
disabled on this page.
You can use either a single-channel (DI0...) or multiple-channels (ALL) to process the Topic
operations. Multi-channel operation is more recommended, because it can help reduce the amount
of network traffic.
In single-channel operation, the values 0 and 1 correspond 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 (uncheck the checkbox) unused Topics to reduce unnecessary processing, as it will
affect operational efficiency.
