IO-Link Master Configuration

Pepperl+Fuchs Comtrol’s IO-Link Master combines the benefits of the IO-Link standard with the EtherNet/IP™ and Modbus TCP protocols. The IO-Link Master effectively shields the PLC programmers from the IO-Link complexities by handling those complexities itself. The result is simplified EtherNet/IP™ and Modbus TCP interfaces, which decreases system development time and installation efforts.

This IO-Link Master features a rugged IP67 slim-line design incorporating two Fast Ethernet ports, eight M12 IO-Link ports with T-Code power connectors. Designed for harsh environments, its machine-mount design uses industrial grade components. The IO-Link Master is easily integrated into a system network and is compatible with existing and new industrial Ethernet installations.
