The control and monitoring interface ("C.M.I." for short) is a web server that creates a connection between a LAN network and the CAN bus components. This device makes it possible to load function data into CAN bus devices, update and remote control them, illustrate online diagrams and log data. Access can be local directly from the PC/network, via Internet and the C.M.I. web portal or via Internet through port forwarding to the router. Data logging of devices with DL Bus is also possible. It was ensured to make commissioning as easy as possible for computer novices as well.
