Quality control system in food industry

Production and storage process in food industry are subjected to specific laws related to quality control; the quality control system based on the Winlog Pro software SCADA platform has been successfully applied in many sectors of food industry; actually it gives the possibility to comply with requested quality control criteria limiting both the investment cost and the production loss due to the installation of the system.

The system provides a continuous monitoring of all the significant variables of the process and generates quality control reports with graphical trends that certify the compliance of the production lot; the system also certifies that the storage process doesn't affect the quality of the stored product and doesn't cause any modification of the original characteristics. Any abnormal condition in the production or storage process is promptly detected and signalled with a local alarm; in case of unattended environment, a SMS can be sent to the cellular phone of a maintenance staff operator.

All information generated can be made available to one or more Client stations (local or remote) linked via a TCP/IP protocol. FOR MORE INFORMATION

Quality control in metal heat treatment

The system has been designed to ensure the quality control for heat treatments in a plant division equipped with heterogeneous furnaces (multi-chamber furnaces, pit furnaces, tempering and hardening furnaces), replacing traditional paper recorders and creating production report. Furnaces are equipped with their own instrumentation (PLCs, Eroelectronic/Gefran controllers, recorders) and can perform different kind of heat treatments (hardening, tempering, annealing, stabilization, normalization). The system gathers heat treatments measures of all division from a parallel data acquisition network without entering any interference to the existing control instrumentation; collected data (temperatures, carbon percentages) are continuously referred to theoretical curves values set in every production recipe to verify the quality of the process. At the end of every production process, reports are generated containing load identification data, process variable curves and alarms. All historical data and reports are exported in a Microsoft Office compliant format and extended to the quality control division. Alarms coming from process and machines are recorded and broadcast to maintenance staff and, in case of not guarded plant, to surveillance staff. Two PClog client stations and a PClog server TCP/IP provide system HMI, ensure data integrity and maintain plant work continuity. This system is well suited in those cases where it is important to have global vision of several process executed by several machines without local HMI. FOR MORE INFORMATION
