Introduction
varies according to the communication baud rate of the master station
,
and the communication data
cable length must comply with the Siemens DB9 wiring standard. Due to reasons such as interference
and cable error
,
transmission distance of the Pro󶍾bus-DP bus reaches approximately 60% of the
theoretic value in the actual environment.
The following table lists the requirements on the baud rate and cable length:
Transmission Rate
Theoretic Transmission Distance
(m)
Actual Reachable Maximum
Transmission Distance (m)
9.6 Kbps to 93.75 Kbps 1000 600
187.5 Kbps 800 480
500 Kbps 400 320
1.5 Mbps 200 160
12 Mbps 100 60
The following table lists the technical speci󶍾cations of cables:
Parameter Type A Type B
Impedance 135 Ω to 165 Ω (f = 3 MHz to 20 MHz) 100 Ω to 130 Ω (f > 100 KHz)
Capacitance < 30 pF/m < 60 pF/m
Resistance < 110 Ω/km Not speci󶍾ed

As shown in the preceding 󶍾gure
,
the communication port uses a DB9 socket. Use Pro󶍾bus-DP cables
for the connection. (Recommended cable: Siemens 6XV1830-0EH10) The following 󶍾gure shows the
connection:
