Note: When using DNP communication between ISaGRAF and the target controller the
DNP Application Layer timeout may need to be increased if a large C/C++
application is added. The default Application Layer timeout of 5 seconds may not be
long enough.
The Run, Stop and Delete buttons apply to the C/C++ program selected from the list of
loaded C/C++ programs. These buttons are disabled when there are no C/C++ programs
loaded.
The Run button stops and restarts the selected C/C++ program in the controller.
The Stop button stops the selected C/C++ program in the controller.
The Delete button stops and erases the selected C/C++ program in the controller.
The Reset button resets the controller. A reset restarts the controller processor, all C/C++
programs and the Ladder Logic program.
The Refresh button refreshes the list of loaded programs and their status.
Click on the column headings to sort the list by that column. Click a second time to reverse
the sort order.
Program Status Dialog
The Program Status dialog displays status information about the programs currently loaded
in the controller. There are two versions of this dialog depending on the type of controller
selected in the Controller Serial Ports Command dialog.
Controllers with firmware version SCADAPack version 1.53 or older, or, SCADAPack 32
version 1.14 or older, so not support the program status feature. The message “The
controller does not support the Program Status feature.” is displayed.
SCADAPack and Micro16 Controllers
When the controller type is SCADAPack or Micro16 controller the Program Status dialog
displays the current state of the IEC-61131 program and the C\C++ program. The state may
be one of the following:
Stopped – program has been downloaded and is currently stopped.
Running – program has been downloaded and is currently running.
No Program – there is no program in the controller.
The Close button closes the dialog.
