Abstract:
1. A control system for a technical process comprising: a measurement and control unit, sensors and actuators controlling said technical process connected by lines to said measurement and control unit, a program unit comprising control modules and instructions; an operating and observation unit having a screen and a keyboard for data input and being linked via a data channel to said program unit whereby data is exchanged between said program unit and said operating and observation unit, and wherein control of said technical process is effected by an operator inputting control instructions into said program unit via said measurement and control unit, wherein said control modules are called in a run time mode and said control comprises elements selected from sequence elements, event elements and function elements; wherein said sequence elements provides process guidance and functions in sequence and said sequence element comprises start module, sequence module and end module; wherein said event elements run independent of said sequence elements and said event elements comprise event modules and security modules; wherein said function elements run parallel to said sequence elements and can be addressed by at least one of said sequence element or said event element; wherein said technical process can be controlled by said operator in a configuration mode wherein an order of operation of said control module elements can be altered graphically and said technical process alters function in response to said order of operation; wherein during operation said control system can access a program unit which can, in turn, initiate said start module and at least one element of said control module; wherein said start module initiates said sequence module wherein each sequence module is processed sequentially and each sequence module can activate a second sequence module of said sequence modules; said function element or said end module, wherein said function element can be initiated by a process incident and can initiate a sequence module, function module or end module; and said end module activatable by one of said start module, said sequence module and said event module.
