8.2 PROFIBUS DP
8.2.1 Commissioning ET 200AL on PROFIBUS DP
Introduction
The commissioning of your distributed I/O system depends on the system configuration. The
following procedure describes the commissioning of the ET 200AL distributed I/O system on a
DP master.
Requirements for the ET 200AL distributed I/O system on a PROFIBUS DP
Note
Performing tests
You must ensure the safety of your plant. You therefore need to perform a complete
functional test and the necessary safety checks before the final commissioning of a plant.
Also plan the tests to include any possible foreseeable errors. This helps to avoid endangering
persons or equipment during operation.
Procedure
The following table shows the chapters/documents in which the required actions are
described.
