The
SIMOTION SCOUT
online help shows you how to design and configure a PROFIBUS or
Ethernet subnet for your application.
6.2.2 Configuring a PROFIBUS subnet
device = node
Convention: All devices connected in a subnet will be referred to hereafter as nodes.
PROFIBUS addresses
In order for all nodes to communicate with each other, you must assign a 'PROFIBUS-address"
to each node before connecting them:
You set the PROFIBUS addresses for each node individually using the programming device
or PC (also by a switch on the slave for some PROFIBUS DP slaves).
The factory settings on the SIMOTION C are address 2 and baud rate 1.5 Mbit/s for both
PROFIBUS DP interfaces X8 and X9.
Tip: Mark the set address on the housing of all nodes in a subnet. You can then always see
which address is assigned to which node in your plant.
The "highest PROFIBUS addresses" are preset for each PROFIBUS subnet. You can change
these default settings.
Rules for PROFIBUS addresses
Before assigning PROFIBUS addresses, note the following rules:
● All PROFIBUS addresses in a subnet must be unique.
● The highest PROFIBUS address in a subnet must be ≥ the largest actual PROFIBUS node
address in this subnet.
Recommendation for PROFIBUS addresses
Reserve PROFIBUS address "0" for a service programming device and "1" for a service
SIMATIC HMI device, which will be connected to the subnet if required.
Recommendation for the PROFIBUS address of the SIMOTION C in case of replacement or
service:
Reserve address "2" for a SIMOTION C. This prevents duplicate addresses when installing a
SIMOTION C with factory setting on the subnet (e.g. when a SIMOTION C is replaced). You
should therefore assign addresses greater than "2" to additional nodes in the subnet.
