ERbic Profibus
Profibus is the most widely used field bus. It is promoted
by Siemens and by organized, interested and committed
manufacturers and users in the PNO (Profibus user organiza-
tion). The IP 20 interface on the device side is standardized
as a 9-pin D-Sub female connector. The max. data transmis-
sion rate is 12 Mbit/s. The cable is a shielded twisted pair
conductor.
The cable sheath is violet and the signal cores are green (A)
and red (B).
With its comprehensive program, ERNI provides customers
with a wide variety of options.
Particular emphasis should be placed on the different termi-
nation technologies, from the traditional screw terminal to the
cage clamp terminal to the IDC terminal.*
