Technical data

Executing the function and
specifying another
breakpoint
Initial situation: the CPU is in the WAIT STATE.
To continue the function, you have two possibilities:
1. Specify the next operation as the
following breakpoint:
Move the cursor down to the next operation to specify the following
breakpoint.
The CPU continues by processing this operation up to the operation
boundary. Then the CPU outputs the data and waits for further
instructions from the PG.
However, if a nested program
execution level interrupts operation processing at the following
breakpoint, the CPU processes the nested program first. Then
the CPU returns to the 2nd breakpoint that you specified.
Note
You cannot specify a following breakpoint when the CPU is in
the STOP mode.
2. Specify a
new breakpoint:
At the PG, specify any other operation in the same block
or in a different block. The CPU continues program processing
until it reaches the new breakpoint. The operation is processed
fully. The CPU then goes to the WAIT STATE and outputs
the data there.
You can also run the program through a whole cycle (cyclic test), by
setting the breakpoint at the same operation as previously in the
WAIT STATE. Remember, however, that the operation must not be
in a program loop. In this case, the loop is run through once; and the
program execution does not go beyond the end of the cycle.
Note
You can call other functions, such as OUTPUT DIR, STATUS
VARIABLES or FORCE VARIABLES in the WAIT STATE.
Once program execution is continued after exiting the WAIT
STATE, the timers and system timers continue to run until the
next breakpoint is reached.
