Function description
4.3.1
Addressing with SafetyBUS p
The SafetyBUS p address of an output is composed of the device address and the consec-
utive number of the FS output (<Device.address>.<Number of output>)
The following SafetyBUS p addresses are possible:
SafetyBUS p network
SafetyBUS p0
SafetyBUS p 1
4.3.2
Addresses in the process image
The module occupies one bit address in the process image. The process image in which
the outputs are shown depends on the configuration of the FS outputs.

4.3.3
FS error behaviour
In the case of a safety-related error on an FS output, all FS outputs in the affected I/O-
Group (SafetyBUS p) are shut down.
In the case of a safety-related error on an FS input, the process image of all FS inputs in
the affected I/O-Group (SafetyBUS p) is set to zero.
The I/O-Group switches to a STOP condition. An error telegram is then triggered on Safety-
BUS p and the error is entered in the PSSuniversal error stack.
