The serial EtherNet/IP Linking Device lets you include any automation device with a serial RS-232/422/485 application interface in an EtherNet/IP-based network architecture. It supports many serial protocols including Modbus, DF1, produce/consume, ASCII and custom protocols.
It is a cost-effective alternative to in-chassis communication modules. The distributed EtherNet/IP Linking Device brings several advantages. Contrary to an in-chassis module, which is physically connected to the PLC, the Linking Device can be mounted close to the connected machine. The benefit is the possibility to establish a connection through a single Ethernet cable instead of multiple network specific cables. The Linking Devices support ODVA’s Device Level Ring (DLR) for ring topology.
Users access serial protocol configuration through their existing Studio 5000 software. All configuration is made inside Studio 5000 where there is support for Process Variable Data Tags and manual and automatic generation of named and structured Studio 5000 Controller Tags without any required user logic.
Since the Linking Devices are stand-alone (distributed), they do not affect PLC backplane performance (PLC execution time), even when large amounts of data are transferred.
The PLC scans the Linking Device as if it were any other I/O device on the network.
