HMS Industrial Networks EtherNet/IP to Modbus-TCPEtherNet/IP Linking Device

The EtherNet/IP to Modbus-TCP Linking Device from HMS Industrial Networks allows users to connect devices on Modbus-TCP to a Rockwell ControlLogix or CompactLogix PLC. Users will benefit from the integration to Rockwell’s Studio5000 Logix Designer, as all configuration is made from inside Studio 5000.

The device makes it possible to include any automation device with Modbus TCP communication into an EtherNet/IP-based network architecture supporting over 8000 bytes of I/O data in total.

Contrary to an in-chassis module which is physically connected to the PLC, the EtherNet/IP to Modbus-TCP Linking Device can be mounted close to the connected devices. This means that it is possible to establish a connection via a single Ethernet cable instead of multiple network-specific cables. All EtherNet/IP Linking Devices from HMS support ODVA’s Device Level Ring (DLR) for ring topology.

All configuration is made inside Studio 5000 where there is support for process variable data tags, as well as manual and automatic generation of named and structured Studio 5000 controller tags without any required user logic.

Since the Linking Device operates standalone (distributed), it doesn’t affect PLC backplane performance, even when large amounts of data are transferred. The PLC simply scans the Linking Device as if it were any other I/O device on the network.
