However, there are two important considerations in this regard:
z Online Change: An online change (partial download) initiated while the controller
is in the RUNNING state returns the controller to the RUNNING state if
successful.
Before using the Login with online change option, test the changes to your
application program in a virtual or non-production environment and confirm that
the controller and attached equipment assume their expected conditions in the
RUNNING state.
NOTE: Online changes to your program are not automatically written to the Boot
application, and will be overwritten by the existing Boot application at the next
reboot. If you wish your changes to persist through a reboot, manually update the
Boot application by selecting Create boot application in the Online menu.
z Multiple Download: SoMachine has a feature that allows you to perform a full
application download to multiple targets on your network or fieldbus.
One of the default options when you select the Multiple Download... command
is the Start all applications after download or online change option, which
restarts all download targets in the RUNNING state, irrespective of their last
controller state before the multiple download was initiated. Deselect this option if
you do not want all targeted controllers to restart in the RUNNING state.
In addition, before using the Multiple Download... option, test the changes to
your application program in a virtual or non-production environment and confirm
that the targeted controllers and attached equipment assume their expected
conditions in the RUNNING state.
WARNING
UNINTENDED EQUIPMENT OPERATION
Always verify that online changes to a RUNNING application program operate
as expected before downloading them to controllers.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
WARNING
UNINTENDED EQUIPMENT OPERATION
Always verify that your application program will operate as expected for all
targeted controllers and equipment before issuing the "Multiple Download…"
command with the "Start all applications after download or online change"
option selected.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
