(or the communication between it and its branching unit is broken for any reason), but all the branching units stay powered and functional, your PC can still communicate with all the other drives. Miscellaneous 9-26 DriveWindow 2 If you have the drive status display on-line, the image in front of the failed drive in the browse tree pane changes to show a question mark. Images of all other drives are shown normally. Also, if you have items, faults, or events of the failed drive on-line in the item sets pane, they will show signal quality bad. The same happens, if you update any off-line item, fault, or event of the failed drive, while power of a drive is down. Items, faults, and events of all other drives are shown normally. When the power is restored (or the broken communication loop is fixed), DriveWindow recovers automatically. Note that qualities of off-line items, faults, and events do not change until you update them. 2.1.3 Branching Units Fail In case of a tree of branching units, if power of one or more branching units fails (or the communications between them and their parent units are broken for any reason), your PC cannot communicate with the drives behind the failing branching units. Miscellaneous DriveWindow 2 9-27 If you have the drive status display on-line, the images in front of the drives behind the failed branching units in the browse tree pane change to show a question mark. Images of other drives are shown normally. Also, if you have items, faults, or events of the drives behind the failed branching units on-line in the item sets pane, they will show signal quality bad. The same happens, if you update any off-line item, fault, or event of a drive behind the failed branching units. Items, faults, and events of all other drives are shown normally. For example, if the root branching unit fails: In case a broken communication is fixed without taking power off from the branching units, DriveWindow recovers automatically. However, when power of the failed branching units is restored, they require re-programming by the DriveOPC communication library. DriveWindow does not know that power has been recovered, and automatic recovery is not possible. You have two main options to recover by yourself: ? Restart DriveOPC, which can be done by disconnecting and re-connecting the OPC Server. ? Command DriveOPC to ask its communication library to restart (re-identify and thus reprogram the DDCS network). Miscellaneous 9-28 DriveWindow 2 Restarting DriveOPC is simpler. You usually use it, if you are willing to lose contents of the monitor and any of the uploaded dataloggers. ? Save your desktop to a workspace file. ? Disconnect the OPC Server. ? Restore the workspace from the file. Restoring also does the re-connecting of DriveOPC. Miscellaneous DriveWindow 2 9-29 Note that qualities of off-line items, faults, and events do not change until you update them. Commanding of DriveOPC to recover from branching unit power fail is more complex. You must use it in case you do not want to stop monitoring, lose the monitor contents, or lose any uploaded datalogger contents. ? Make sure that all failed branching units have been powered and also all drives behind them. ? Add an item with OPC address Communication.Restart into the browsed item set. ? Write the value ON to the added item. ? Wait while the DriveOPC communication library does its identification and re-programming of the branching units. or or Miscellaneous
