application
application

The continuous increase of energy costs together with the possibility to select the most suitable contract among different energy providers make more and more convenient a supervisory system able to ensure a continuous monitoring of power consumption and energy costs of low and medium voltage networks. Thanks to Winlog Pro SCADA software, it has been possible to develop many supervisory applications able to provide both the continuous monitoring of the electrical network and the possibility to increase the overall efficiency. Winlog Pro includes a series of internal objects especially designed to display electrical schemes and cabinets, to monitor power consumption, to calculate energy costs using both real or simulated calendars with different fares according to date and time. Display of electrical schemes with animated switches and lines changing colour according to current path allow highlighting of energy flows, quick spotting of abnormal operation and prevention of possible power overflow. Monitoring of power consumption and energy costs of single user lines and of the overall network in the form of daily, monthly and yearly bar charts provide an ideal report for analysis and optimization of the electrical network; the possibility to program the yearly calendar with different fares according to date and time is an essential tool to prepare a budget plan and select the contract more suitable for anyone's requirements.

Quality control in metal heat treatment

application
application

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 reports.

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.
