3SPECIFICATIONSMELSEC-F3.4 Ethernet Module Function ListCommunication usingMC protocolCommunication usingthe fixed bufferSending e-mailThis section shows a list of Ethernet module functions.(1) Basic functions of the Ethernet moduleThe Ethernet module can perform the communications shown in the table belowvia TCP/IP or UDP/IP communication.Function Description Reference sectionSubset of Acompatible 1EframeReads/writes PLC data from/to an external device. Chapter 8, 9Procedure exist Sends/receives arbitrary data between the PLC and the Chapter 6No procedure external device using the fixed buffer of the Ethernet module. Chapter 7Sends data via e-mail.• Sending by the PLCChapter 10(2) Additional functions of the Ethernet moduleThe following table lists the additional functions of the Ethernet module that canbe used.Function Description Reference sectionRouter relay communication (router relayfunction)Existence check of external device (Existencecheck function)Communication via pairing openMELSOFT connection (GX Developer, etc.)Performs data communication via a router or gateway. (The routerrelay function is not a function by which the Ethernet module works asa router.)Checks whether or not the external device is working normally after aconnection is established (open processing).Pairs and then opens a reception connection and a transmissionconnection (for fixed buffer).Connects MELSOFT products (GX Developer, etc.) via TCP/IPcommunication (through the in-house LAN, etc. ). It is possible toconnect multiple MELSOFT products at the same time. It is alsopossible to connect multiple MELSOFT products simultaneously.Section 5.3Subsection 5.2.2 andSection 5.5Section 5.7Section 1.2 (4)Manual of eachMELSOFT product(3) Status check of the Ethernet moduleChecks that the Ethernet module is working and can communicate normally.Function Description Reference sectionSelf loopback testChecks the Ethernet module's sending/receiving function and lineconnection status.Subsection 4.7.1Hardware test Tests the RAM and ROM of the Ethernet module. Subsection 4.7.2Communication error storageWhen a data communication error occurs, this function stores theerror information (error log), including the message subheader andIP address of the external device for a maximum of 16 pairs in thebuffer memory.Chapter 113 - 63 - 6
