6.6.13 'Online' 'Step in'
Shortcut: <F8>
A single step is executed. The program is stopped before the first instruction of a
called POU.
If necessary, there will be a changeover to an open POU.
If the present position is a call-up of a function or of a function block, then the
command will proceed on to the first instruction in the called POU.
In all other situations, the command will function exactly as 'Online' 'Step Over'.
6.6.14 'Online' 'Single Cycle'
Shortcut: <Ctrl>+<F5>
This command executes a single PLC Cycle and stops after this cycle.
This command can be repeated continuously in order to proceed in single cycles.
The Single Cycle ends when the 'Online' 'Run' command is executed.
6.6.15 'Online' 'Write values'
Shortcut: <Ctrl>+<F7>
With this command, one or more variables are set – one time only! – to user defined
values at the beginning of a cycle. (see 'Online' 'Force values' for setting permanently)
The values of all single-element variables can be changed, so long as they are also
visible in Monitoring.
Before the command 'Write values' can be executed, a variable value must be ready to
be written:
For non-boolean variables a double mouse click in performed on the line in which a
variable is declared, or the variable is marked and the <Enter> key is pressed. The
dialog box 'Write variable <x>' then appears, in which the value to be written to the
variable can be entered.
