Safety: Passivation and Reintegration of F-I/O
In the event of an error on an F-I/O (e.g. a channel fault), the F-I/O (or the affected channel) switches to safe mode. In this state of “passivation”, substitute values are automatically output instead of process values.
After clearing the error that caused the passivation, the switchover from substitute values to process values can occur. The switchover can be done automatically or after a user acknowledgment in the safety program. The switchover is referred to as “reintegration”.
The present safety application example describes the passivation and reintegration of F-I/O according to the following content:
- Manual and automatic reintegration
- RIOforFA PROFIsafe profile
- Value state and QBAD
- Differences in evaluation with F-CPUs S7-1200/1500 and S7-300/400
If you would like to reproduce the functions described here, the according TIA Portal project is available for you for the S7-1200 and the S7-1500.

Siemens provides products and solutions with Industrial Security functions that support the secure operation of plants, systems, machines and networks. To protect plants, systems, machines and networks against cyber threats, it is necessary to implement (and continuously maintain) a holistic, state-of-the-art Industrial Security concept. Products and solutions from Siemens are only one part of such a concept. It is the customer’s responsibility to prevent unauthorized access to the customer’s plants, systems, machines and networks. Systems, machines and components should only be connected with the company’s network or the Internet, when and insofar as this is required and the appropriate protective measures (for example, use of firewalls and network segmentation) have been taken. In addition, Siemens’ recommendations regarding appropriate protective action should be followed. For more information about Industrial Security, visit http://www.siemens.com/industrialsecurity. Siemens’ products and solutions undergo continuous development to make them even more secure. Siemens strongly recommends to carry out updates as soon as the respective updates are available and always only to use the current product versions. Use of product versions that are no longer supported, and failure to apply latest updates may increase customer’s exposure to cyber threats. To stay informed about product updates as they occur, subscribe to the Siemens Industrial Security RSS feed at http://www.siemens.com/industrialsecurity.
