    shielded twisted pair cable, the longest communication distance is 9.6km (requires additional relay), and the maximum length is 90km when using fiber optic cable. The maximum cable length of each segment of Profibus-DP is related to the transmission rate. Different media, different baud rates, and different distances that signals can be transmitted are shown in Table 7.

    VP(Pin 6) B-line(Pin 3) A-line(Pin 8) DGND(Pin 5) Figure 2 PROFIBUSCable terminator for cable (pin number of 9-pin D-type connector) Profibus's bus terminator consists of a pull-up resistor and a pull-down resistor. When there is no station transmitting data on the bus (ie idle time), these two resistors force different state voltages to a certain value, thus ensuring that there is on the bus.
