The ModbusAsyncBooleanWritable component has the following slots:
- Status: point’s status;
- Available states: OK (point is working properly), Disabled (point is disabled, the Enable slot is in false), Down/Timeout (point is not available), Device Down (device is not available), Wrong address format (incorrect address format according to the address format setting slot), Device disabled (device is disabled), Network disabled (Modbus network is disabled).

- Available options: fast, normal, slow;
- Write Type: writing mode;
- Available options: COV (only on input change), COV_PollFrequrency (on input change and periodically), PollFrequrency (only periodically), COV_LinkSet (link-back forward triggered by COV);
- Trigger: forcefully send the value (on rising edge), regardless of the current poll mode;
- Out: output slot, the current value of read/write register;
- In: input slot.
The ModbusAsyncBooleanWritable component has the following actions available under the right-click:
- Set True/Set False: writes a value to the In slot and sends it to the device (not active when slot In has a connected link);
