][Funktionsbeschreibung SN p PLC1
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 modules.
The head module receives signals
from the connected input/output
modules; it processes these signals
in the user program and passes
them on to the other network subscribers.
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
Description".
Wiring
][Verdrahtung Kopf Versorgung
The requirements of the supply
voltages can be found in the chapter
entitled "Technical Details".
Safe electrical isolation must be ensured
for the external power supplies
that generate the supply
voltages. Failure to do so could result
in electric shock.
The external power supplies must
comply with the current applicable
standard EN 60950-1, EN 61140,
EN 50178 or EN 61558-1.
The maximum current load for the
periphery supply on the module bus
is 10 A. Please refer to the derating
diagram in the chapter entitled
"Function Description".
The maximum current load for the
C-rail is 10 A. Please refer to the derating
diagram in the chapter entitled
"Function Description".
Permitted infeed at the C-rail:
– PE
– 0 V
– Shield
– - 30 VDC ... +30 VDC
– - 48 VAC ... + 48 VAC
Earth the 0 V supply on the periphery
supply or monitor each supply
group for earth faults.
The connection of the 0 V supply to
the central earth bar or earth fault
monitor must be in accordance with
the relevant national regulations
(e.g. EN 60204-1, NFPA 79:17-7,
NEC: Article 250).
Details of the minimum range for
cable cross sections on connection
terminals can be found in the section
entitled "Technical Details".
Use copper wiring.
