KUNBUS-COM EtherNet/IP Slave discontinued
KUNBUS-COM EtherNet/IP Certificate

The KUNBUS-COM communication interfaces (EtherNet/IP piggyback card, option card) were created on the basis of the KUNBUS-IC family. This variant (EtherNet/IP, serial to Ethernet, RS232) is provided with high-quality plug-in connectors for the bus connection, an SMC plug with 32 pins to the application or the control, the optoelectronic couplers, memory, bus drivers, and the micro controller.

Your control becomes EtherNet/IP-enabled simply by plugging-in the control card or via a cable. Because of the uniform pin-out of all COM modules, they can be replaced easily by other variants (for example PROFINET, EtherCAT, etc.).
