Assigning An Io Device To An Io Controller - Siemens SIMATIC ET 200AL System Manual

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).
Procedure
To assign IO devices to an IO controller, proceed as follows:
1. Place the pointer of the mouse over the interface of the IO device.
2. Press and hold down the left mouse button.
3. Move the pointer.
The pointer now uses the networking symbol to indicate "Networking" mode. At the same
time, you see the lock symbol on the pointer. The lock symbol disappears only when the
pointer is over a valid target position.
4. Now move the pointer onto the interface of the IO controller. You can keep the left mouse
button pressed or release it when performing this action.
5. Now release the left mouse button or press it again (depending on your previous action).

Result
You have assigned an IO device to an IO controller.
