SICK CMF400-3101 EtherNet TCP/IP Fieldbus Gateway

The SICK CMF400-3101 EtherNet TCP/IP Fieldbus Gateway is a compact industrial gateway that bridges Ethernet TCP/IP networks with a SICK fieldbus interface, enabling data exchange between a PLC or control system on an Ethernet network and field devices. It features an RJ45 Ethernet port and is designed for harsh environments with an IP65-rated enclosure. Identified by part number 1026357, the CMF400-3101 is documented in SICK’s CMF400 fieldbus gateway lineage and is marketed specifically as an EtherNet TCP/IP Fieldbus Gateway. Configuration and operation rely on TCP/IP socket communication to read and write data from connected field devices, as described in the official CMF400-3101 operating instructions. Typical applications include integrating SICK field devices such as sensors and scanners with EtherNet/IP or other Ethernet-based PLCs to enable remote data access, control, and data acquisition over a standard Ethernet network, making it suitable for automation, packaging lines, and warehousing environments.
