### Operation details ### Operation details
While the input and discrete input registers are scanned with the configured scanrate, an action on a coil according to a received message is issued immediately. At the same time the all input registers are scanned. While the input and discrete input registers are scanned with the configured scanrate, an action on a coil according to a received message is issued immediately. At the same time the all input registers are scanned.
Using a configuration option it is possible to disable the publishing of analog change event - if only periodic information (like for a thermometer or so) is required.
The MQTT messages related to change events of input or discrete input registers are marked as //retained//. The MQTT messages related to change events of input or discrete input registers are marked as //retained//.
