Description
An MQTT server that mediates messages (MQTT broker)
The product name of the software package for the MELSEC programmable controllers
Data to be exchanged between the sender (publisher) and receiver (subscriber)
A protocol capable of one-to-many asynchronous communications.
The sender of a message is called a publisher, the receiver is called a subscriber, and an entity playing an
intermediate role is called a broker.
The term "publish" means "send", and "subscribe" means "receive".
A key to be used for messaging.
In the topic hierarchy, a slash (/) is regarded as a delimiter. For example, when multiple sensors send their
individual information to the topic, the messages can be appropriately organized according to their installation
location and device name.
This function sends a Will message with a specified Will topic name to subscribers when the publisher is
disconnected and the server communications are disabled.
If any unexpected disconnection or such an event occurs, subscribers can judge that the publisher is
disconnected.
