SingLe ²ine Network ±nstaLLation
Features
–
SNI uses the cabling infrastructure of the energy supply as the basis for the transmission of
communication signals
–
Easy installation as only supply cables need to be connected
–
Drive networks can be implemented with up to 100 m extensions and 10 slaves
–
Routing of bus cables or 24 V supply to drives not necessary
–
No risk of hidden faults in the bus wiring
–
Reduced startup time
–
Shorter project runtimes/reduction of project costs
PossibLe appLications
–
Installation topology for easy installation of MOVIGEAR
®
/ DRC.. drive systems for conveyor
systems that require variable speeds or local positioning
–
SNI components in combination with MOVIGEAR
®
actuators and DRC.. in SNI design as extensi-
on to process more distributed sensors without additional infrastructure
AppLication exampLes
–

NEW:
SN± components
–
CSW maintenance switch
- Possibility to disconnect single SNI actuators individually
- Communication to all other actuators is maintained
–
SNI I/O system CIO:
- Networking of process-relevant, not directly assigned sensors via the SNI infrastructure
- Intelligent preprocessing of sensors and integration into the CCU structure
