6.6.6 'Online' 'Stop'
Symbol: Shortcut <Shift>+<F8>
Stops the execution of the program in the PLC or in Simulation Mode between two
cycles.
Use the 'Online' 'Run' command to continue the program.
6.6.7 'Online' 'Reset'
This command resets – with exception of the retain variables (VAR RETAIN) - all
variables to that specific value, with which they have got initialized (also those
variables which have been declared as VAR PERSISTENT !). If you have initialized the
variables with a specific value, then this command will reset the variables to the
initialized value. All other variables are set at a standard initialization (for example,
integers at 0). As a precautionary measure, »PLC Designer« asks you to confirm your
decision before all of the variables are overwritten. The situation is that which occurs
in the event of a power failure or by turning the controller off, then on (warm restart)
while the program is running.
Use the 'Online' 'Run' command to restart the program.
See also 'Online' 'Reset (original)', 'Online' 'Reset (cold)' and - for an overview on
reinitialization - Remanent variables.
6.6.8 'Online' 'Reset (cold)'
This command corresponds to 'Reset', but besides of "normal" and persistent variables
also sets back retain variables (!) to their initialization values. The situation is that
which occurs at the start of a program which has been downloaded just before to the
PLC (cold start). See in this connection also 'Online' 'Reset', 'Online' 'Reset Original' and
- for an overview on reinitialization - Remanent variables.
6.6.9 'Online' 'Reset (original)'
This command resets all variables including the remanent ones (VAR RETAIN and VAR
PERSISTENT) to their initialization values and erases the user program on the
controller. The controller is returned to its original state. See in this connection also
'Online' 'Reset', 'Online' 'Cold Reset' and - for an overview on reinitialization -
Remanent variables.
