CONTROL SYSTEMS OF THE HEAT AND THERMO-CHEMICAL TREATMENT EQUIPMENT MANUFACTURED IN THE
INSTITUTE OF PRECISION MECHANICS

SUMMARY
In the paper has been presented conceptual system of computer controlling and archiving atmosphere heat
treatment processes. The system is designed on the base of programmable logic controller (PLC), which controls
and monitors process in one stand of heat treatment. Several such stands work in a net, and they are monitored
or may be controlled by a PC. This PC also is used for editing and for archiving a report of heat treatment
processes..

Keywords
