NOTICEWhen observing the network packets via Wireshark®,checksum offloading often causes confusion as thenetwork packets to be transmitted are handed over toWireshark® before the checksums have been calculated.Wireshark® shows these empty checksums as invalid,even though the packets contain valid checksums whenthey leave the network hardware later.Use 1 of these 2 methods to avoid this checksumoffloading problem:• Turn off the checksum offloading in the networkdriver if possible.• Turn off the checksum validation of the specificprotocol in the Wireshark® preferences.Additional settings for indirect communication overEtherCAT®Set the IP address of the EtherCAT® Master:1. Open the TwinCAT® System Manager.2. Select [I/O-Configuration → I/O Devices → Device1(EtherCAT®)] and check the IP-address in theAdapter tab.The IP-address of the PLCs network adapter cannot be a link-local address (so not in the range of169.254.0.1 to 169.254.255.254).3. If necessary, change the IP-address inside the IPv4Protocol properties according to the givenoperating system. This can be done on thecontroller locally or via Remote Desktop.Activate IP routing on the EtherCAT® Master:NOTICEThe procedure described here can vary depending onthe type of PLC and operating system installed.1. Open the TwinCAT® System Manager.2. Click on Advanced Settings… under [I/O-Configu-ration → I/O Devices → Device1 (EtherCAT®)] inthe EtherCAT tab.3. Select EoE Support in the Advanced Settingswindow.4. Enable Connect to TCP/IP Stack in the WindowsNetwork section.5. Enable IP Enable Router in the Windows IP Routingsection.6. Reboot the PLC for the changes to take effect.Set the IP address of the EtherCAT® slave (servo drive orSAB):1. Open the TwinCAT® System Manager.2. Click on Advanced Settings… under [I/O-Configu-ration → I/O Devices → Device1 (EtherCAT®) → Box1 (VLT® Servo Access Box L1 → Drive 2 (VLT®Integrated Servo Drive ISD 510)] in the EtherCATtab.3. Select [Mailbox → EoE] in the Advanced Settingswindow.4. Enable Virtual Ethernet Port and enter a valid IPAddress.5. Each slave in the configuration requires an IP-address. This address is reassigned with everytransition from INIT to Pre-Operational state of theslave state machine. The IP communication of theslaves is deactivated per default.NOTICEThe last number of the IP address is the ID that is usedin the ISD Toolbox to identify the device.5.3.2 Network Settings for DirectCommunication with EthernetPOWERLINK®Disable all network protocols except TCP/IPv4 on thenetwork interface used for direct Ethernet POWERLINK®communication. This prevents other PC software or theoperating system using this network interface for othertasks, such as file and printer sharing and networkdiscovery. Disabling these protocols reduces the number ofnon-relevant packets sent over the network interface andthus reduces the overall network load.How to disable all unused protocols on the networkinterface on the PC:1. Open the Network and Sharing Center.2. On the left, click on Change adapter settings.3. Right-click on the network interface used forfieldbus communication and select Properties.4. Uncheck all checkboxes except the one forInternet Protocol Version 4 (TCP/IPv4).Operation with ISD Toolbox Programming GuideMG36D102 Danfoss A/S © 01/2017 All rights reserved. 1115 5
