Introduction.

Workshop PG5
Instructionlist
Break points:
Often you would like your program to stop at a given event, say you want to
stop the machine as soon as the EndSwitch is activated or as soon as the temperature
stored in the Register 200 reaches the value 23.
The “break point function window allows you to do just that.
While your online with the PCD press the BreakPoint icon :
In the window select the conditions you want to set.
Example: Run the PCD until the register R 200 has the value 23.
As soon as you press “
the PCD does go into conditional run.
Conditional run means that the PDC isn’t running at full speed but it executes
every instruction and after each program step the PCD checks whether the condition
was met or not. The condition is saved in the list so you don’t have to reenter
the same conditions over and over again.
So in our example the PCD will continue to run in conditional run unti the
register reaches the value 23.
The “RUN” LED on the PCD blinks if it’s in conditional run.
In the PG5 a conditional run is indicated by the RUN ICON
which changes between red and green.
Clear-Stop clears the conditional run and puts the PCD in stop.
Clear-Run clears the conditional run and keeps the PCD running.
