6.2.4 Switches

The PROFIBUS DP Slave firmware reads the position of two address switches to configure the

PROFIBUS station address.

Table 16: Pin assignment address switch (NRP 10-DPS)

The switches are BCD coded with 10 positions. Example of a switch: COPAL Type: SA-7111TA,

see http://www.copal-electronics.com

For details about the circuit for the host system see Figure 21: Schematic NRPEB-CCS and

NRPEB-DPS (Part 1) on page 62.

The meaning of the switches

is explained in section Address switches (S1, S2) for PROFIBUS DP

on page 42.

6.2.5 SYNC

There are no signals on SYNC0 and SYNC1 because the PROFIBUS DP Slave firmware does not

generate SYNC signals.
