PROFIBUS DP Interface

XDPSLAVE – PROFIBUS DP
Interface
Transmission rate in kbits/s
Max. segment length in m
Optionally, the connection XDPSLAVE provides a PROFIBUS DP SLAVE
interface according to DIN EN 50170, Part 2. This interface allows to
request the states of the M-Keys available for devices with keypad (see
section M-Keys in chapter 6 on page 6-6 and 6-10).

The bus cable is specified as cable type A according to EN 50170, part 8-
2. It must comply with the following cable parameters:
Surge impedance at a frequency
within a range from 3 to 20 MHz
Operating capacity
Loop resistance
Outside diameter
Core cross-section
