Communication and configuration
In SW67E21, configure EtherCAT, read/write variables and the OPC UA Server. The tool exports an ESI file for configuring the EtherCAT Master; define the corresponding data areas in its project as well.
The gateway is neither an EtherCAT Master nor an OPC UA Client. Distinguish the EtherCAT and Ethernet ports before connection; check the required OPC UA security against the specific firmware and client.
Supply and accessories
Please provide the complete order code. If you need a power supply, connection cables or help with configuration, include them in your enquiry. We will confirm the scope of supply and required accessories for your installation in the quotation.
Documentation and software
Diagrams and hardware version

The images help identify the hardware version. When replacing an older unit, compare its label, connectors and dimensions; we will confirm the version to be supplied in the quotation.
Frequently asked questions
Is knowing the two protocols enough?
The device roles, physical interfaces and data to be transferred must also be checked. The gateway is neither an EtherCAT Master nor an OPC UA Client. Distinguish the EtherCAT and Ethernet ports before connection; check the required OPC UA security against the specific firmware and client.
How is this converter configured?
In SW67E21, configure EtherCAT, read/write variables and the OPC UA Server. The tool exports an ESI file for configuring the EtherCAT Master; define the corresponding data areas in its project as well.
What information should I send to check the selection?
Send the exact device models at both ends, the protocols and communication roles, the number of devices and the required values. For a PLC, include the firmware and method of accessing its data.
