Assigning An Io Device To An Io Controller - Siemens SIMATIC PROFINET Function Manual

Parameter assignment/addressing

3.1 Assigning an IO device to an IO controller

Adjusting the hardware to the project requirements
You need to configure hardware if you want to set up, expand or change an automation
project. To do this, add hardware components to your structure, link these with existing
components, and adapt the hardware properties to the tasks.
The properties of the automation systems and modules are preset such that in many cases
they do not have to be assigned parameters again.
Parameter assignment is however needed in the following cases:
● You want to change the default parameter settings of a module.
● You want to use special functions.
● You want to configure communication connections.
3.1 Assigning an IO device to an IO controller
PROFINET IO System
A PROFINET IO system is comprised of a PROFINET IO controller and its assigned
PROFINET IO devices. After these devices have been placed in the network or topology
view, STEP 7 assigns default values for them. Initially, you only have to worry about the
assignment of IO devices to an IO controller.
Requirement
● You are in the network view of STEP 7.
● A CPU has been placed (e.g., CPU 1516-3 PN/DP).
● An IO device has been placed (e.g., IM 155-6 PN ST).
