ModbusAsyncBooleanWritable

The ModbusAsyncBooleanWritable is a component responsible for sending and reading Boolean values from the device. The component has to be placed under the ModbusAsyncDevice component.

The ModbusAsyncBooleanWritable component has the following slots:

• Status: shows the point’s status;

• Fault Cause: shows the fault cause description;

• Fault Status: informs about the point’ error status (true: point read/write error);

• Enable: enables or disabled the point (true: point enabled, false: point disabled);

• Address Format: allows to set the register address format (Modbus, decimal);

• Address: allows to set the register address;

• Poll Frequency: allows to set the reading poll frequency (fast, normal, slow);

• Write Type: allows to set the writing mode (COV: only on input change, COV_PollFrequency: on input change and periodically, PollFrequency: only periodically, COV_LinkSet: only on input change using the "reverse following the link" function);

• Trigger: allows to force sending values on rising edge;

• Out: the output slot, the current value of read/write registry;

• In: the input slot.

The ModbusAsyncBooleanWritable component offers the following actions, available in the context menu:

• Set True/Set False: writes a value to the In slot and sends it to the device (not active if the In slot has a link connected);

• Write: sends the value from In slot to the device;

• Send Value: sends the user value from the pop-up window, without changing the In slot;

• Read: reads the value from the device and sends it to the Out slot.
