For many years, HORN^® has been a solution partner of Siemens.

The measuring complex collects data from a system of sensors and sends it to I/O modules.

At this stage the electric signals are processed and transmitted to the higher-level process control system. The programmatical linking of all analogue and digital signals is effected in the automation device. The measured values are processed and scaled for the control complex.

THE SYSTEM IS BASED ON 3 LEVELS:

Level 1: Monitoring and visualising the central/decentralised systems as well as controlling and regulating the entire process. A major part of the control is managed by SPS and/or level 1 automations.

Level 2: The main function is to optimise the operation of level 1 and to output actuating variables and control points

Level 3: Serves for planning, quality control and documentation

The collected data is processed and sent to higher-level production planning software via interfaces. These MES and/or ERP systems can be integrated in a user-friendly way using an OPC solution.

The custom-built software controls all important parameters of melting, forming and annealing of the glass. For all critical processes, redundancy is implemented via a backup system. Switching between these systems can be performed “shock-free”.

Visualisation is available at operator stations and at decentralised operating panels.

All HORN^® machines and equipment have a high level of automation, whereby maximum process and machine safety are achieved. Maintenance effort and routine activities are reduced to a minimum. This results in optimum production and longevity of the plants.
