Figure 4.1 represents the PROFIBUS DP network connector, highlighting the switch for the insertion of the termination resistance in the last slave line.
Special care shall be put in ensuring shield continuity, which can be achieved by laying the bare cable braiding on the metal connector (ref. 2 of the
figure); moreover, the slave connection cable shall always be connected to the left, following the colour sequence for the connection to the screw
terminal board inside the connector.
