Two-roll mill Buhler SZAE-900 for primary grinding of chocolate mass. The need to replace obsolete control system equipment (year of manufacture - 1993, controller discontinued)
Reduced downtime thanks to the reliability of the new control system
Save maintenance resources and reduce troubleshooting time from hours to minutes with control system diagnostics
Reduce troubleshooting time and reduce operating costs through the use of modern unified components
Creation of a unified system for monitoring performance indicators with the possibility of analytics and scaling
Modernization of the control system
Replacement of controller equipment: modern universal controller Siemens SIMATIC S7-1500 and touch operator panel Siemens SIMATIC Basic Panel
Replacement of low-voltage switching equipment: introductory machine, starting assemblies, intermediate relays
Replacement of sensors: mass sensor on shafts, pressure sensors
Control system in accordance with the international standard OMAC PackML (ISA-TR88.00.02), providing data for calculating OEE (Overall Equipment Effectiveness) and RCA (Root Cause Analysis of Stoppages); interface for communication with MES / MOM, a set of modes, states and parameters of the machine, the reasons for transitions between states, a standardized appearance
