MacroView software outruns Pentium

A process control software program ran for more than 15 years without problems at a plant in Victoria until the hardware failed.

The MacroView system was installed in December 1995 to monitor and control a waste water recycling plant in Altona run by Hoeschst Australia.

In 1997, Kemcor Australia bought Hoechst’s Australian operations and in 1999 became Qenos as a joint venture between Exxon-Mobil and Orica.

The system was running on a Pentium 90 system with 60 MHz processor and 16 Mb RAM. ((Pictured here is Chris Schleising with the Pentium 90 system.)

The operating system was SCO Open Desktop and the server was connected to Siemens S5 PLC via a serial link.

Sentient Computing process control engineer Chris Schleising said: “The system ran quietly in the corner for years without issues.

The client had to search around to find documentation on who provided the software and came to us for help.” Schleising saved the client’s data from the hard drive, re-built and upgraded the machine and the software and sent it back to Qenos in Victoria.

The MacroView process control software was developed in Perth in the late 1980s by the Vector Technology group and is now owned by Sentient Computing whose owner, Doug Bester, was one of the original developers.
