Restart The Controller; Online With The Controller; Upload To The Controller - Allen-Bradley SoftLogix 5800 User Manual

Restart the Controller

You restart the controller by either of these methods:
• Restarting the computer
• Removing and reinserting the controller in the virtual chassis
After restarting the controller, you must upload or download from the Logix
Designer application before you can go online with the controller. This is because
the project file (.ACD) contains explicit knowledge of the physical memory
addresses used by the controller. When you restart the controller, all of the
physical addresses for the controller are regenerated. Note that as long as the
controller is not restarted, you can go online and offline as many times as
required.

Online with the Controller

You must save the Logix Designer application project after a download
completes, or you will not be able to go online with the controller. After
downloading, the physical address information has changed. The Logix Designer
application prompts you to save and indicates that a change has occurred even
though you might not have made changes to the project. Saving the project stores
the physical address information into the ACD file.
An upload recovers all of the information that was downloaded to the controller,
including documentation. This is because of the persistent storage feature that
you enable by specifying a periodic save interval (see
the persistent storage copies the entire project file to the controller. The
controller opens and goes online with the project file so that any edits made by
Logix Designer application workstations are saved into the persistent image (the
controller's copy of the project file). Online edits are saved to the persistent image
immediately; tag data values are saved to the persistent image at every periodic
save interval (10 min default). If the periodic save is disabled, tag data values are
not saved, but online edits are still saved to the persistent image.
The SoftLogix controller maintains a change log that holds 999 entries. This
means that as you edit a Logix Designer project file, you must save the project file
before you make 999 changes. If you make more than 999 changes to a project,
you will not be able to go back online without performing an upload or
a download.

Upload to the Controller

If your project has edits and you want to upload the project to the controller, the
Logix Designer application prompts you to save the project before uploading.
Regardless of your choice, the edits are saved before the upload occurs. This
happens because the edits are already stored in the controller as you make
the edits.
