Cable specification
Recommendation: Use a cable in accordance with cable specifi-
cation as per EN 50170 part 2 (cable A).
- surge impedance: 135-165 Ohm (3-20 MHz)
- capacitance per unit length: < 30 pF/m
- loop resistance: < 110 Ohm/km
- cross-sectional area: > 0.34 mm

Use special bus connector plugs for PROFIBUS, e.g. the fol-
lowing 9-pin plugs from Siemens AG:
Part number
Description
6ES7 972-0BA10-0XA0
Terminating resistor can be switched in;
vertical cable exit;
baud rate 9.6 kbit/s...12 Mbit/s
6ES7 972-0BB10-0XA0
as above, but with conduit connection
PLEASE NOTE
Use plugs with terminating resistors if you are fitting the
SPC200 to the end of a segment.
