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.

Slots

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 (true: point read error);
  • Enable: enables or disables 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;
  • Nr Bit: allows to set the bit number in the register;
  • Poll Frequency: allows to set the reading poll frequency (fast, normal, slow);
  • Write Type: allows to set the writing mode (COV: only on the In slot change, COV_PollFequrency: on the In slot change and periodically, PollFequrency: only periodically, COV_LinkSet : only on the In slot change using the "reverse following the link" function);
  • Trigger: allows to trigger the remote enforcement of sending (on rising edge);
  • Out: the current value of reading bit;
  • In: the input slot.

Action

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.
