Baud rate The baud rate is the speed at which data is transmitted. It specifies the num-
ber of bits transmitted per second (baud rate = bit rate).
Baud rates of 9.6 kbps to 1.5 Mbps are possible with the ET 200L.
Bus The common transmission path to which all nodes are connected. It has two
defined ends.
In the case of the ET 200, the bus is a two-wire cable or a fiber-optic cable.
Bus connector The physical link between the bus nodes and the bus cable.
In the case of the ET 200, there is a bus connector with and without connec-
tions for the programming unit and with IP 20 and IP 65 degrees of protec-
tion.
