Industrial RFID reader supporting the Modbus RTU protocol, dedicated to PLC

« ‹ of 2 › »

IND Modbus is an industrial RFID reader equipped with an RS485 port for Modbus RTU communication, an USB port for configuration, two digital inputs and two relay outputs. The reader is housed in a weatherproof, IP65 rated enclosure. Multiple RFID standards are supported, dependent of the version:

Transponders

  • Dependent on the device version,
  • Tag reading distance: up to 8cm.

Modbus RTU

The main communication protocol of this reader is Modbus RTU via the RS485 port. Intuitive configuration software allows selection of transmission speed, parity as well as the PDU address of the device, so it can be easily integrated into various applications. The module supports the following Modbus RTU functions:

  • 0x01 Read Coils,
  • 0x03 Read Holding Register,
  • 0x05 Write Single Coil,
  • 0x06 Write Single Register,
  • 0x0F Write Multiple Coils,
  • 0x10 Write Multiple Registers.

Configuration

To use the full capabilities of the reader, it must be configured accordingly. Using the configuration program (available below), the user can set the transmission speed, set the readers response to card application, check the status of inputs, configure outputs and set the card reading mode.

Attention! For correct reader operation, it is necessary to close the Inveo RFID Config application first.
