Note: EtherNet/IP (Ethernet Industrial Protocol) is a specific application layer protocol used in advanced industrial automation environments and is not short-hand for Ethernet Internet Protocol. Grid Connect engineers are available to answer your EtherNet/IP questions.

Convert the protocols of Modbus to EtherNet/IP with a Grid Connect RS485/RJ45 adapter. The NET485-EIP-MB is an intelligent adapter with Modbus master and EtherNet/IP slave software built-in. Convert any single Modbus RTU or ASCII device with an RS422/485 serial port to an EtherNet/IP server. Extend the life and application of existing Modbus devices by efficiently using them in an EtherNet/IP environment.

By using standard EtherNet/IP explicit messaging, any EtherNet/IP configuration tool (not included) can be used to configure the NET485 EtherNet/IP Modbus adapter. Modbus register data is mapped to EtherNet/IP assembly data during the configuration process. This means the NET485-EIP-MB will appear as an EtherNet/IP slave with all Modbus Serial communications hidden from the EtherNet/IP master.

The NET485-EIP-MB supports a Modbus RTU/ASCII RS422/485 serial connection with data rates up to 231 kbps. A standard RJ45 network connection supports auto-sensing 10BASE-T and 100BASE-TX Ethernet. Ideal for industrial applications, the NET485-EIP-MB has an extended -30ºC to +65ºC temperature range and is powered by an 8-24 V terminal block connection.

Grid Connect also offers an embedded (GC-XPORT-EIP-MB) version of the Modbus Serial to EtherNet/IP device.

The knowledgeable and experienced engineers at Grid Connect provide complete technical support for the NET485-EIP-MB. We offer phone support and on-line chat support during regular business hours.
