ModbusAsyncRegisterBitWritable

The ModbusAsyncRegisterBitWritable component is responsible for sending to and reading Boolean values from a bit in a specified register in the device. The component has to be placed under the ModbusAsyncDevice component.

The ModbusAsyncRegisterBitWritable 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;

  • Available information: true (point read error);

• Enable: enables or disables the point;

  • Available options: true (point enabled), false (point disabled);

• Address Format: allows to set the register address format;

  • Available options: Modbus, decimal;

• Address: allows to set the register address;

• Nr Bit: allows to set the bit number in the register;

• Poll Frequency: allows to set the reading poll frequency;

  • Available options: fast, normal, slow;

• Write Type: allows to set the writing mode;

  • Available options: COV (only on the In slot change), COV_PollFequrency (on the In slot change and periodically), PollFequrency (only periodically), COV_LinkSet (link back-forward triggered by COV);

• Trigger: allows to trigger the remote enforcement of sending (on rising edge);

• Out: the current value of reading bit;

• In: the input slot.

The ModbusAsyncRegisterBitWritable component offers the following actions:

• Set True/Set False: writes the 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 the In slot to the device;

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

• Send Value: sends the value to the device, without changing the value on the In slot.
