Activating And Deactivating Components And Technology Objects; Activating And Deactivating Nodes On The Profibus Or Profinet Io - Siemens SIMOTION Function Manual

Activating and deactivating components and
technology objects
This section describes how PROFIBUS DP slaves and technology objects are activated and
deactivated.
5.1

Activating and deactivating nodes on the PROFIBUS or PROFINET IO

The user has configured and programmed a maximum configuration. The user program
deactivates bus nodes that are not available or not required in order to achieve the following:
● The cyclic load (data exchange) between the DP master and the DP slaves (PROFIBUS)
● The processing of alarms is suppressed for deactivated nodes.
● No bus fault is signaled for PROFIBUS or PROFINET IO nodes which are not available.
● DP slaves (drives) re-synchronize with the DP cycle clock.
The user program can also activate further nodes that are required, for example, in another
production phase.
Note
If the DP slave or the IO device is integrated in PROFIsafe communication (e.g. SINAMICS
with SINAMICS Safety Integrated Extended Functions): Deactivation of a bus node will result
in PROFIsafe errors with corresponding responses in the failsafe control (F-CPU). If
necessary, the control will shut down all other PROFIsafe nodes.
