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.
The IO-Link Master easily installs on a standard DIN rail and incorporates two Fast Ethernet ports, eight pluggable/removable screw terminal IO-Link ports. This product is designed with industrial grade components and redundant power inputs to make it exceptionally reliable for critical applications. The IO-Link Master is easily integrated into a system network and is compatible with existing and new industrial Ethernet environments.
