The SPC200 in Debug mode
The following peculiarities apply in Debug mode:
The program tested in Debug mode is processed in task
A. The appropriate I/O signals of task A are effective.
During the testing of programs for the Record Selection
mode, the NC records in the debug window are selected
and started with
the command [Single step]. Sequence
control through the inputs RECBIT.. and the input CLK_A
is still effective. However, this cannot be displayed in the
debug window.
When programs are being tested for Start/Stop mode, the
individual records are activated and started by WinPISA in
the SPC200. WinPISA also takes into account here jumps
and
any I/O signals present. The individual NC records
can be started one after the other when there is a positive
edge at the START input. However, this cannot be shown
in the Debug window.
Caution
If an error occurs in transmission in the operating mode
Start/Stop during Debug mode, WinPISA can no longer
reset the sequence control transferred from the SPC200.
If errors occur, make sure that the SPC200 reacts as
expected when the Debug mode is exited. If necessary,
restore the normal status with the [Program reset]
command in the [Online] menu.
Please note
During the Debugmode WinPISA takes over the sequence
control of the SPC200.
This results in a different run time performance of the
program sequence.
