Unlike business systems and even process control systems, SCADA systems incorporate a unique blend of real-time, rapid-time, soon-time, ''background,'' and even off-line processes. Depending on the computing power available, and the architecture chosen, the SCADA system builder may be able to use high-level languages to implement these processes. Advances in computer power and language efficiency have made it possible to minimize the use of assembly codes. A structured, modular, software design enables, the use of a mixture of various high-level languages, each with its own particular strengths. Experience gained over many years on projects executed by Rexnord Automation have ranged from SCADA systems based on the Digital Equipment Corp. PDP-11 computer family with software written in assembly code MACRO and a ''home-brew'' operating system, through SCADA systems based on the DEC VAX computer family with software written in ''C'' and running under the VMS system.
