The Busmaster-L2 transmits data received over the interface to the L2-Bus DP. It is equipped with one RS-485 (or TTY) and one RS-232 interface for connecting to peripherals, and one L2 bus interface for connecting to the L2 Bus DP. The Busmaster-L2 takes the data from the connected devices and makes it available to the SPS via the L2-Bus. The slave address of the Busmaster can be changed at any time via a DIL switch. The Busmaster-L2 continuously transmits 60 data-words to the SPC. Received data must be managed using the SPC-internal program. The Busmaster automatically detects the baud rate set on the L2-Bus.
