Connection to SafetyNET p
Functions
}
The SafetyNET p interface enables safety-related and non-safety-related data transfer
between the PSSu system and other network subscribers.
}
The head module receives signals from other network subscribers; it processes these
signals in the user program and passes them on to the connected input/output mod-
ules.
}
The head module receives signals from the connected input/output modules; it pro-
cesses these signals in the user program and passes them on to the other network sub-
scribers.
}
If a fault occurs, the module switches the connected failsafe outputs to a safe condition.
MAC address
}
The MAC address is a factory-set default. It can found on the labelling strip on the front
of the module.
INFORMATION
Further information on SafetyNET p can be found in the "PSS 4000 System

PROFIBUS-DP with PROFIsafe
4.8.1
Connection to PROFIBUS-DP with PROFIsafe
PROFIBUS is an open fieldbus standard whose communication is defined in the interna-
tional standards IEC 61158 and IEC 61784. Further provisions have been defined in spe-
cifications published by the PROFIBUS User Group. These specifications are available
from PROFIBUS International (see www.profibus.com).
The head module has a PROFIBUS-DP interface with PROFIsafe. Communication via
PROFIsafe is defined in the international standard IEC 61784-3-3.
4.8.2
Selector switch for setting the station address
}
The station address of a PSSu is set via the "ADDRESS" DIP switch. The DIP switch is
binary coded. Permitted station addresses are in the range 0
D
... 125
D
. If station ad-
dress 126
D
is set via the DIP switch, the address can be assigned via the Master. The
Set Slave Address command (SSA) must be run for this purpose.
}
The station address of an F-device is set via the "F-ADDRESS" DIP switch. The DIP
switch is binary coded. Permitted station addresses are in the range 1
