Communication and configuration
In SW67861, configure the Modbus RTU Slave baud rate, parity, address and register map. The Ethernet port is used for configuration and updates. In the configurator, assign device IODD files to individual channels and configure process value reading and writing.
Prepare the IODD file and process data length and meaning for each connected device. The -4A version has four Class A ports; check connected device current requirements and the available power supply when designing the installation.
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. Prepare the IODD file and process data length and meaning for each connected device. The -4A version has four Class A ports; check connected device current requirements and the available power supply when designing the installation.
How is this converter configured?
In SW67861, configure the Modbus RTU Slave baud rate, parity, address and register map. The Ethernet port is used for configuration and updates. In the configurator, assign device IODD files to individual channels and configure process value reading and writing.
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.
