OverviewThe automation and supervision of SMI conveyors are handled by the VLS PRO (VaryLine System), an advanced hardware/software system developed by SMI based on the PROFIBUS field bus. The VLS PRO controls up to 121 inverter-equipped motors and combines, in a single compact control unit, the line control PC and a multi-language man–machine interface (POSYC). The reduced size of the control unit allows flexible positioning at strategic points along the line.
Main features and advantages- Distributed architecture based on inverter-driven integrated motors, reducing space for electrical panels and simplifying wiring
- Single industrial PC (POSYC) combining control functions and operator interface for simplified operation
- Compact control unit enabling flexible placement on the line
- Lower line wiring costs and shortened wiring time
- Modularity allowing multiple VLS units within the same system
- Operational flexibility and quick changeover
- Reduced maintenance requirements
- Multi-language man–machine interface
- Low energy consumption
Operator functions (from POSYC VLS control unit with LCD touch screen)- Set conveyor operation parameters
- Adjust conveyor speed according to product flow and type
- Automatically stop and start conveyors according to required product flow
- Collect and export production data
- Plan and schedule maintenance operations
