7.4.8 Breakpoint Positions in Text Editor

Breakpoint positions include all positions in a program at which values of variables

can change or where the program flow branches off. (Exception: function calls. If

necessary, a breakpoint in the function must be set here.) At the positions lying

inbetween, a breakpoint would not even make sense, since nothing has been able to

change in the data since the preceding breakpoint position.

This results in the following breakpoint positions in the IL:

• At the start of the POU

• At every LD, LDN (or, in case a LD is located at a label, then at the label)

• At every JMP, JMPC, JMPCN

• At every label

• At every CAL, CALC, CALCN

• At every RET, RETC, RETCN

• At the end of the POU

Structured Text accommodates the following breakpoint positions:

• At every assignment

• At every RETURN and EXIT instruction

• in lines where conditions are being evaluated (WHILE, IF, REPEAT)

• At the end of the POU

Breakpoint positions are marked by the display of the line number field in the color

which is set in the project options.
