    7 Modbus/TCP Communications Outline 7-1-1 Modbus/TCP Communications • A V780 Reader/Writer can perform Modbus/TCP-compliant message communications with the host device (PLC). • Communications between the host device (PLC) and the V780 Reader/Writer are performed on a cli- ent-server basis using the TCP/IP protocol. The computer, PLC, or other host device is the client and the Reader/Writer is the server.

    (normal commands) Multiple Registers (FC16). These are called normal commands in this manual. This function code has a unique format that was defined by OMRON. This function code is used to reduce command/response exchanges between the host FC100 device and Reader/Writer and give priority to the performance of communications with (expanded command) the host device.
  • Page 156 7 Modbus/TCP Communications TCP/IP Socket Communications System (FC03, FC16, and FC100) The expanded command that has a unique format defined by OMRON (FC100) cannot be sent with a Modbus/TCP Class 0-compliant protocol. The TCP/IP socket communications of the host device (PLC) are used instead.

Using a Normal Command (FC03 or FC16) With a normal command, the maximum size of data that you can read from an RF Tag is 120 words.
  • Page 167 7 Modbus/TCP Communications If you want to check the EPC code or reception level when communications with the RF Tag are suc- cessful, send a GET RF TAG ADDITIONAL INFORMATION command after the response to the com- munications command has been received. The reception level from the RF Tag that was just communicated with will be returned.
