6.4 Settings for CP 443-5 Ext as PROFIBUS master
Introduction
In PCS 7, each CP 443-5 Ext acting as a PROFIBUS master has its own PROFIBUS network
and its own DP master system assigned (single master system).
Two PROFIBUS masters in each case from both racks form a redundant master system in H
systems.
The settings shown below apply to both H systems and standard systems.
Note the following when using SIMATIC PDM in the project:
The integrated DP interfaces of a S7-400 CPU also support the "Data Record Routing" function
in configured firmware version V5.1 and above, and can therefore also be used as a fully-
fledged DP master. For all CPUs with lower firmware versions the "Data Record Routing"
function must be established with a CP 443-5 Extended.
