Thanks to simple wall or DIN-rail assembly, decentralised control tasks can be elegantly completed using these modules. The connection to the PC is made via the RS 232 interface and to the object via a detachable screw terminal. The RS 485 interface operates with 300 bps to 115 kbps. The accompanying floppy disk contains the necessary configuration and auxiliary programmes. Measuring data can be visualised as they are supported by DaisyLab. This takes over the function of the PC once the program has been downloaded into the communications controller.
