7 Modbus/TCP Communications7 - 2 UHF RFID System V780-series Reader/Writer User’s Manual (Z389)7-1 Outline• 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.• The message that the host device (PLC) sends to the Reader/Writer is called a command. The mes-sage that the Reader/Writer returns is called the response.Additional InformationModbus/TCP ProtocolThe Modbus/TCP protocol is a communications protocol developed for PLCs by Modicon Inc.(AEG Schneider Automation International S.A.S.). It is an open standard and has been used for a variety of industrial devices.A query in Modbus/TCP communications is called a command in this manual.The Modbus/TCP function codes that are supported by the V780 Reader/Writer are given in the follow-ing table. 7-1-1 Modbus/TCP Communications7-1-2 Modbus/TCP Function Codes Supported by the V780Function code DescriptionFC03 and FC16 (normal commands)These function codes comply with Modbus/TCP Class 0.The basic Modbus/TCP function codes are classified in Class 0.Class 0 contains the following two functions: Read Multiple Resisters (FC03) and Write Multiple Registers (FC16).These are called normal commands in this manual.FC100 (expanded command)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 device and Reader/Writer and give priority to the performance of communications with the host device.This is called an expanded command in this manual.Host device (client)Reader/Writer (server)Ethernet CableTCP port number: 502CommandResponsePower Supply Cable

The TCP/IP socket communications of the host device (PLC) are used instead.Refer to 7-2 Message Formats on page 7-5 for details on the expanded communications commands.Refer to 7-4 Communications Procedure on page 7-11 for information on creating a program for TCP/IP communications.7-1-3 Communications SystemModbus/TCP Communications System (FC03 and FC16)TCP/IP Socket Communications System (FC03, FC16, and FC100)Host device (client)Reader/Writer (server)Ethernet CableFC03 or FC16TCP port number: 502CommandResponsePower Supply CableModbus/TCP communications instructions Modbus/TCP Unit or other applicable UnitHost device (client)Reader/Writer (server)Ethernet CableFC03, FC16, or FC100TCP port number: 502CommandResponsePower Supply CableSocket communications instructions Ethernet Unit or other applicable Unit
7 Modbus/TCP Communications7 - 4 UHF RFID System V780-series Reader/Writer User’s Manual (Z389)Precautions for Correct UseCommunications Units and communications commands that support the Modbus/TCP protocol support only function codes that comply with Modbus/TCP Class 0. Therefore, the function code FC100 for expanded commands cannot be used.You can set any IP address for the V780 Reader/Writer.For details, refer to 7-6-5 Reader/Writer Setting Commands: Network Settings on page 7-54 or Setting the IP Address of the Reader/Writer from a Web Browser on page 5-4.Normally, port number 502 (01F6 hex) is used for Modbus/TCP communications.With the V780 Reader/Writer, you can change the port number to between 1,024 and 65,535 (0400 hex and FFFF hex).For details, refer to ?8-2-3 ????????

You can specify options to get the EPC of the RF Tag, the reception level, or other communications information together with the normal data for the command.For commands with the multiaccess specification, the communications information specified with the option is returned in the response for the command that gets the execution results, i.e., the two com-mands are used together.For commands with the Modbus expansion, the communications information specified with the option is returned as an attachment to the response.OptionsOption Specification Examples:Specify 0001 hex to have the EPC attached.Specify 0003 hex to have the EPC and reception level attached.Specify 0011 hex to have the EPC and diagnostic results attached.Options Supported by RF Communications CommandsOK: Option can be specified, No: Option cannot be specified.

After you establish a connection, send commands and receive the responses.1Connection Processing: Opening a SocketSend a request for a connection from the host device to the Reader/Writer and establish a TCP connection. Monitor for connection timeouts as required.2Command Send Processing: Sending Socket DataSend the command from the host device to the Reader/Writer in a message.Monitor for send timeouts as required.3Response Reception Processing: Receiving Socket DataAt the host device, wait to receive the message from the host device and receive the response.Monitor for reception timeouts as required.4Disconnection Processing: Closing the SocketSend a request for a disconnection from the host device to the Reader/Writer and disconnect the TCP connection.

7 Modbus/TCP Communications7 - 12 UHF RFID System V780-series Reader/Writer User’s Manual (Z389)Precautions for Correct UseAccess to a Reader/Writer is possible from only one host device at a time.If a host device B connects to a Reader/Writer while another host device A is already con-nected to it, the connection between host device A and the Reader/Writer will be automatically disconnected and a connection with host device B will be established.If an error response is received, you can check the most recent command error information or com-mand error log in the Reader/Writer to get details on the nature of the error. An error has occurred if the function code in the response that was returned from the Reader/Writer is 80 hex higher than the func-tion code in the query.You can do this by sending a GET MOST RECENT ERROR INFORMATION command or GET COM-MAND ERROR LOG command from the host device or by using the Web browser interface through the Web server. 7-4-2 Error Response Reception ProcedureError occurs.Error detected.Host device (client)Reader/Writer (server)Command executionGET MOST RECENT ERROR INFORMATION command sent.(Or, GET COMMAND ERROR LOG command sent.)Error information returned.Command sent.Response returned.Function code + 80 hex

To read more data than that, you must use more than one READ DATA or WRITE DATA command, or use an expanded command.If communications with an RF Tag are not possible, a “failure in slave device” exception code (04 hex) is returned in an error response.

7 Modbus/TCP Communications7 - 14 UHF RFID System V780-series Reader/Writer User’s Manual (Z389)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.With an expanded command, the maximum size of data that you can read from an RF Tag is 2,048 words.If an error occurs in the RF Tag communications, the error code is returned with the response. No addi-tional command is required to check the error code.You can also specify a command option to have the EPC code or reception level returned with the other data.When you send an RF Tag communications command with multiaccess communications, the Reader/Writer communicates with more than one RF Tag in the communications field.The Reader/Writer will communicate with all of the RF Tags in the communications field within the com-munications timeout time (64 max.) and then return a response.Using an Expanded Command (FC100)7-4-4 RF Tag Communications Command Procedure for Multiaccess CommunicationsHost device (client)Reader/Writer (server)RF Tag ACommand executionREAD DATA communications command sent.Communications fieldRF Tag memory read/written.GET RF TAG ADDITIONAL INFORMATION command sent.Reception levelResponse returned.Response returned.Host device (client)Reader/Writer (server)RF Tag ACommand executionEXPANDED DATA READ communications command sent.Communications fieldRF Tag memory read/written.Error code+ EPC code+ Reception levelRead data (2,048 words max.)Response returned (2,048 words max.)

The communications results will contain the number of RF Tags detected, the error code, and, for READ DATA, the EPC code.If the option is specified, the reception level information is also attached.3Repeatedly Getting the ResultsExecute the command to get the results once for every RF Tag that was detected.The number of RF Tags that was detected by the Reader/Writer is included in the response to the command to get the results.
