4.12.4.1 Effective Direction from the Input Module to the Processor Module (3)
Noise blanking with effective direction from the input module to the processor module is
performed by the processor module. Noise blanking suppresses the transient interference on
the input module and on the buses (system bus and I/O bus). Noise blanking on the input
module can be deactivated in the properties (SILworX) (default = Activated), see the input
module manuals. Noise blanking on the buses is always active and cannot be deactivated in
SILworX.
4.12.4.2 Effective Direction from the Processor Module to the Output Module (4)
Noise blanking with effective direction from the processor module to the output module is
performed by the output module and is always active. Noise blanking suppresses the transient
interference on the bus.
4.12.4.3 Effective Direction from the Processor Module to the Output Module (7)
Noise blanking with effective direction from the output module to the processor module on the
system bus is performed by the processor module. Noise blanking suppresses status
acknowledgments of the output module such as SC/OC detection. Noise blanking on the output
module can be deactivated in the properties (SILworX) (default = Activated), see the output
module manuals.
