Cable Distance
Cable distance depends upon the baud rate being used. See the following table.
Baud Rate Segment Distance Total Distance (All Segments)
9.6 – 93.75 Kb 1,200 m (3,930 ft) 12,000 m) (39,300 ft)
187.5 Kb 1,000 m (3, 280 ft) 10,000 m (32,800 ft)
500 Kb 400 m (1,310 ft) 4,000 m (13,100 ft)
1.5 Mb 200 m (660 ft) 2,000 m (6,600 ft)
3 to 12 Mb * 100 m (330 ft) 1,000 m (3,300 ft)
* Baud rates greater than 1.5 Mb require special connectors and repeaters.
4.4.2 Configuring a Profibus Network
You may configure the Profibus network using either PLC Workshop or Siemens Com
Profibus. The 2500 controller supports up to 112 slaves and a maximum of 64 module slots
per slave.
PLC Workshop
The Profibus configuration tool is integrated into PLC Workshop V 4.52 and above.
1. Select the PLC Utilities/PLC Configuration menu item.
2. Click on the Profibus I/O button to open the Profibus configuration window.
3. Configure the Profibus network and assign slave I/O points to I/O register addresses.
COM Profibus
Configuring the Profibus network is a multi-step process.
1. Configure the Profibus network using the COM PROFIBUS software.
2. Export the configuration as a .2bf file.
3. Merge the resulting .2bf file from the Profibus configuration into your programming
software.
4. Using the programming software, assign the slave I/O points to I/O register
addresses.
For additional information regarding Profibus configuration, see the help documentation for
PLC Workshop and Com Profibus.
