Considerations for Automatic Shutdown and Startup

Keep these considerations in mind when you are planning for automatic system shutdown and startup operations.

• Stopping the batch system automatically can be accomplished by using the functionality provided by most intelligent UPS systems. Typically, a UPS has an option that allows you to configure a command file, such as a batch file, that is run on loss of power. Parameters, such as time delay that are associated with this process can usually be configured. This method provides a very easy way to stop the batch run-time system.

• Depending on the number of run-time and client applications that are started, the batch system may take several minutes to completely shut down. The UPS must provide ample time for a complete, undisturbed shutdown.

• After an Exit and Shutdown occurs (- x), a confirmation message appears if the Environment Display is active. You must manually acknowledge this message to completely close the Environment Display application. However, failure to manually acknowledge this message does not result in any problems or loss of data. All AVEVA Batch Management services and databases close before this confirmation message.

• Starting the batch system automatically can be accomplished by creating a batch file that starts the etcmds program. You must place this batch file in the Windows Startup program group.

• The start run-time option does not initiate any client applications such as Batch Scheduler and Batch Display.

• Exercise caution when restarting the batch system. The AVEVA Batch Management System retains knowledge of all active batches and phases. If the controller resets with a power outage, the batch system and the controller logic may lose synchronization. You should implement procedures to recover from such a situation. Options include manually restarting all previously active phases, putting a UPS on the controller, or aborting all active phases prior to shutdown.
