5.1 CPU 41x-3 PN/DP as DP master / DP slave
5.1.1 Overview
Introduction
This chapter describes the properties and technical specifications that you require when you
use a CPU 41x-3 PN/DP as a DP master or as a DP slave and configure it for direct data
exchange.
Declaration: Since the DP master / DP slave response is the same for all CPUs, we will
therefore simply refer to the CPUs in the following as CPU 41x-3 PN/DP.
Further Information
For information on the hardware and software configuration of a PROFIBUS subnet and on
diagnostic functions within the PROFIBUS subnet, refer to the STEP 7 Online Help.
