RTES communicates in real time with the physical components of the system (motors, valves, temperatures, switches, counters, set points, etc.)
Each component is represented by an object.
The interactions between the objects are defined with a set of rules.
The rule editor allows you to define/change the rules, using simple boolean-arithmetic expressions.
An inference engine executes the rules in real time.
RTES also includes:

• multiport communications
• alarm definition and handling
• procedural batch language interpreter
• file handling
