Networking; Configuring; Configuring A Profibus Subnet - Siemens SIMOTION C 230-2 Operating Instructions Manual

Laying the cables
Only one or two shielded cables can be attached per shielding terminal (see table "Assignment
of cable cross-sections and shielding terminals"). Attach the cable to the stripped cable shield.
The stripped section of cable shield must have a minimum length of 20 mm. If you require more
than four shielding terminals, start the wiring on the back row of the shield connecting element.
Tip: Make sure you allow a sufficient length of cable between the shielding terminal and the
front connector. This will, for example, ensure that if a repair is required, you can unplug the
front connector without also having to remove the shield terminal.

Configuring

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.
