Introduction to OptoDataLink Seminar
When: Thursday, September 9, 10:00 a.m. Pacific Time (GMT 17:00)
Duration: 45 minutes plus Q&A
Recommended for: All customers (some knowledge of PAC Control may be helpful)
- What if your hard drive fails while you're developing a PAC Control strategy?
- What if you need to update an old strategy built by someone else?
- What if you want to revert to a previous version of a PAC Display project?
You can plan now for future needs, simply by archiving your PAC Control and PAC Display files.
This OptoNews edition shows you how to archive PAC Control strategies. Next time, we'll cover PAC Display project files.
Archive to the computer during development.
If your hard drive fails or the PAC Control files you're developing become corrupted, you'll be glad you archived the strategy files to your computer and saved them in a separate location. Here's how:
1. To make an archive file manually, with the strategy open in Configure mode, choose File > Archive Strategy.
2. Or for automatic archiving, choose File > Strategy Options. Click to put a check mark next to "Archive strategy to disk when strategy is closed."
For both manual and automatic archives, the archive file is created on your PC in the same directory as the strategy file. The date and time are included in the filename.
3. Copy archive files to an external hard drive, CD, or USB key. Keep another copy in a separate physical location.
Archive to the controller when development is finished.
When you've almost finished development, begin archiving to the controller itself. An archived strategy can be pulled from the controller months or even years later.
1. With the strategy open in Configure mode, choose File > Strategy Options.
2. Put a check mark in "Archive strategy to disk when strategy is downloaded," and put another check mark in "During download, save archive to the control engine and save strategy to flash memory."
Only the latest strategy archive is kept on the controller; any older archive is replaced. The strategy is also saved to flash memory, so it is still there if power to the controller is lost.
For more on archiving strategies, see the PAC Control User's Guide, form #1700. Look in the Index under "archiving strategies."
