A loop structure may be regarded as a special case of alternative branching

The transitions and steps must continually alternate

A step can have the same nam

Function block RS has a primarily resetting system, having bistable memory with preferred status 1.

Function block SR contains a dominant setting flip-flop (bistable memory with preferred status 0).

For AND-operation, Only if all of the input signals have values of 1, does the output signal assume a value of 1.

For OR-operation, If the input signal is 0, the output signal will acquire the value 1, and vice versa.

For Negation, If at least one input signal has the value 1, the output signal adopts that value.

A unique element of the step element is the initial step

The sequential function chart programming language is primarily based on the IEC 60848 function chart planning language

Identification. In edge evaluation, this function block is utilized in detecting rising or positive edges (write the code name of the function block).

Identification. What type of function block in the edge evaluation if the input CLK changes from 1 to 0, and the output Q assumes a 1-value for one processing cycle? (write the code name of the function block).

Identification. What contains a number of execution parts of the control program?
