Our KUNBUS-COM communication interfaces have been created as an evolution of the KUNBUS-IC family. The COM modules EtherCAT (Ethernet, EtherCAT slave) are equipped with plug-in connectors for bus connection, optoelectronic couplers, memory, a microcontroller, bus drivers and a SMC plug with 32 pins to control the application.

Furthermore, the KUNBUS-COM EtherCAT can be connected by cable or simply by plugging to the control card. Because of the uniform pin-out of all COM modules, they can be replaced easily by other variants (for example PROFINET, Ethernet/IP, etc.). Accordingly, they can be used as EtherCAT option cards.
