Vintage SCADA software
- We strongly believe that it was the first SCADA software
in Yugoslavia implemented on the IBM PC computer.
- Development was based on our earlier experience in SCADA
design with VMS and PDP11 and iRMX86 and intel i260 machine.
- The best we could buy 1989 in Yugoslavia was IBM PC compatible
computer on 12MHz i80286 with 1MB RAM memory and EGA graphics card.
- Project started on August 1989 and was finished and tested up to March 1990.
- Data acquisition and control was implemented over 16 PLC based on the Intel MCS-51 (8031).
- All code was writen on the Microsoft C 5.1 and MS DOS 3.3.
Main features
- The acquisition and control of data for the temperature and flow of energofluids (hot and cold water, gas, technological water, etc.)
- Maintaining and controlling the fire alarm system.
- Managing the climate system.
- Observing the consumption of electric energy, as well as the monitoring of both active and reactive power.
- The list of alarms and warnings.
Technical data
- Most control loops were in 16 PLCs that communicated with the
central IBM PC over the RS485 interface.
- Тhere are 128 analog inputs and 64 analog control outputs.
- Тhere are 256 digital inputs and outputs.
- Еnergy combustion monitoring and database archive.
- Аctive and reactive electric power, measurement, storage and overflow alarms.
