Communication and configuration
In SW67908, configure RS485, baud rate, parity and the Modbus Slave address. Then define HART addresses, variables and mapping. The Ethernet port is used for configuration and updates.
Prepare HART instrument types, addresses, supported commands and required variables. The converter supply and the supply connection for HART devices are separate connection points. Select the HART loop source, current requirements, load resistance and switch positions according to the actual installation and the specific model connection diagram.
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 HART instrument types, addresses, supported commands and required variables. The converter supply and the supply connection for HART devices are separate connection points. Select the HART loop source, current requirements, load resistance and switch positions according to the actual installation and the specific model connection diagram.
How is this converter configured?
In SW67908, configure RS485, baud rate, parity and the Modbus Slave address. Then define HART addresses, variables and mapping. The Ethernet port is used for configuration and updates.
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.
