PROFIBUS DP Interface
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 135 to 156 ohms
Operating capacity
≤
30 pF/m
Loop resistance
≤
110 ohms/km
Outside diameter > 0.64 mm
Core cross-section > 0.34 mm²
