Communication and configuration
In SW67E04, configure the Modbus TCP Server and EtherCAT read/write variables. The software exports an ESI file for the EtherCAT Master; align its data areas with Modbus TCP register mapping.
This model does not independently poll other Modbus TCP Servers. It requires a connected Modbus TCP Client and EtherCAT Master. EtherCAT and Ethernet port pairs are not interchangeable.
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. This model does not independently poll other Modbus TCP Servers. It requires a connected Modbus TCP Client and EtherCAT Master. EtherCAT and Ethernet port pairs are not interchangeable.
How is this converter configured?
In SW67E04, configure the Modbus TCP Server and EtherCAT read/write variables. The software exports an ESI file for the EtherCAT Master; align its data areas with Modbus TCP register mapping.
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.
