PRESENCE BUTTON
The presence button is mapped via registers 1x0001 to 1x0003. If the button is not asSigned any LED
(LED mode is not equal to a value of 5) the button states can be recorded via the following register:
1x0001 Button pressed = 1, detection via edge change
1x0002 Button released = 1, detection via edge change
1x0003 Button status, current button status at time of query
The button information that is triggered by an edge change can be saved until the next MODBUS telegram query
"Function 02 Read Discrete Input" in order to enable the reliable detection of button activation even with longer bus sampling
cycles (e.g. 1 second).
When assigning the button to a LED (LED mode contains a value of 5), the LED status will change automatically every time
a button is pressed. The corresponding LED must be switched on via the function 05 Write Single Coil.
The LED status can be queried via register 1x0001.
The register 1x0002 has no function.
The register 1x0003 shows the current button status at the time of query.
The LED status can also be set or deleted via the function 05 Write Single Coil Bit 6.
