Example of a cement mill with CEMAT functionality SPC (Scalable Production Control) for easy recipe and material management

The functionality for the cement and mining industry supplied by CEMAT is integrated into the system structure of SIMATIC PCS 7 during installation, and can be classified as follows:

• Software blocks for automation tasks typical at customers in the cement and mining industry
• Modules for controlling motors, valves, and flaps and for processing of analog and binary signals
• Modules for structuring and simplified operation of the plant in groups and paths
• Scalable Production Control (SPC) for recipe-based control strategies
• HMI components with:
  • Library for all control system objects with information, diagnostic, and multimedia dialogs
  • Message system with industry-specific service functions
  • Diagnostic system for fast recognition of faults and reduction of downtimes
  • Additional functions such as signal tracking and signal status information
  • APL-style design
• Web-compatible visualization of process displays and faceplates
• Management information: listing and statistics functions as well as long-term archiving
• Maintenance function with:
  • Definition of maintenance intervals for analog and binary modules
  • Recording of maintenance actions
• Comprehensive multimedia support, e.g. from:
  • Video sequences for operating and service personnel
  • Showing of pictures in process pictures
  • Integration of AutoCAD drawings (DXF format)
  • Integration of plant plans
  • Context-sensitive provision of information depending on place and time

Scalable Production Control (SPC)

SPC modules can be used in the automation system to save, import and export parameters for recipe-based control strategies. There are various SPC block types for the various data types of the parameters. These block types can be freely interconnected depending on the scale and requirements. Recipes can therefore be structured from verified CEMAT modules depending on the requirements of the plant and the configuration limits. Symbols and faceplates are available for the visualization.

The operator can also use one of these standard faceplates to switch between recipes. This enables an automated type change, taking into account the configurable boundary conditions, such as delay time, etc. The SPC Material Manager, which also supports online operation via WinCC, enables flexible assignment of materials to storage locations.

Note on the upgrade

Existing installations in CEMAT V6.1 and higher can be upgraded to CEMAT V9.0 with the CEMAT upgrade package V9.0. One CEMAT upgrade package is required for each existing CEMAT station.
