The electrical and software components of Stetter batch control systems are constantly developed further according to requirements of modern Mixing Plant technology incorporating the latest technologies available in the range of hardware and software tools.
The modular design of the control systems enables modifications for different customer requirements with a high effectiveness in cost and time.
The mainly features of Stetter batch control systems are:
Modern bus technology
Integration of standard components (world wide availability)
Iintegration of calibrated digital weigher scales
Enhancement in mobility of mobile plants with pluggable cable connections
The control software is seperated in a data administration (PC) and a process control modul (PLC). These two moduls are closely connected but nevertheless independant of each other. The data administration modul is running on a WindowsTM-based computer. It manages all the data of the database (order administration, mixed designes, plant set-up data etc.) The software for controling the plant and the batching and dosing software is implemented in a PLC.
The most important features of the Stetter control software are
Different user languages
Networking with local EDP system
Controlling different plants with one database (MC400 only)
Plant depended statistics (MC400 only)
Parallel production of two different mixing recipes (MC400 only)
Storing calibrated data
Re-printing of calibrated delivery notes
Correction of aggregate moisture in the running batch
Correction of sand with respect to fine material in recycled water
Self correction of over running material with respect to filling levels of the weighers
Collecting all the weights of manual dosed materials
