The device address of a PSSu is set via the two rotary switches “x 10”
and “x 1”.

Permitted device addresses are in the range 32
plies if the PSSu system is configured for SafetyBUS p 1 in the Safety-

BUS p Configurator on the PSS WIN-PRO system software. The offset

The INTERBUS parameters can be used to display diagnostic data and
FS section data in the ST-PII. These INTERBUS parameters are set via
the DIP switches labelled “DIAG”, “FS IN” and “FS OUT”.

The INTERBUS parameter “DIAG” determines whether the diagnostic
bytes are transferred. The four diagnostic bytes are displayed in the ST­PII.

INFORMATION

Further information on the structure and contents of the diag­nostic byte can be found under “Operation”.

The INTERBUS parameters “FS IN” and “FS OUT” determine whether
the FS inputs and the switch status of the FS outputs on the PSSu sys­tem are transferred. The FS inputs and the status of the FS outputs are
displayed in the ST-PII. The FS inputs/outputs cannot be selected indi­vidually per module.

The following functions are available via the USB port:

 Show actual hardware
 Comparison of actual/registered hardware
 Display and update firmware versions
 Setting the parameters for the ST section

Parameters for the module's ST section can either be set via the fieldbus
interface or via the USB port. Parameter setting via the USB port has pri­ority over parameter setting via the fieldbus interface. Once parameters
for the the head module have been set via the USB port, the ability to set
parameters for the module via the fieldbus interface is disabled. The dis­able can be lifted in the PSSuniversal Assistant.

Procedure for connecting the head module via the USB port:

 Connect PC to head module via USB cable.
 Install USB driver.
 View the actual hardware registry in the PSSuniversal Assistant and

call up other functions.

This way it is possible to copy and edit an existing configuration in the
PSSuniversal Assistant.

INFORMATION

The USB driver can be found on the PSSuniversal Assistant

(1) There are two levels of overtemperature.

 Too warm:

If a module's temperature exceeds a threshold value, the module
sends a warning to the head module. If the temperature drops back
below the threshold value, the module sends an all-clear.

 Too hot:

If a module's temperature exceeds a further threshold value, the mod­ule sends an error message to the head module and triggers an I/O­Group stop.

Further information on PSSu error messages is available in the online
help for the system software.

the following reasons, which are stored in the error stack:

1. The head module cannot determine the registered hardware. Possible
causes:

 Module bus is incomplete
 Terminating resistor is missing.
 A module is defective

Remedy: Correct the hardware registry.

2. Error: A module is missing. Possible cause:

 The module has been removed.
 The module has an error and is no longer registering after a reset.
 The module has an error and switches to a system stop.
 The module no longer has a voltage supply.

Remedy: Rectify the above points.
