flash memory, use PAC Manager’s Inspect window to check the Status Read area. See the PAC Manager
User’s Guide for instructions.
Updating, Running, or Testing a Strategy
The card can also be used to update, run, or test a PAC Control strategy. This ability is useful when the
controller is not on the network or PAC Control isn’t available. Both regular strategies and Secure Strategy
Distribution (SSD) strategies can be used.
You can write to the card in one of two ways: either use your PC to FTP files to the card in the controller, or use
a card reader with your PC and copy files with Windows Explorer.
CAUTION:
Before saving to flash memory, make sure you know what is on the card! ALL IP address, configuration
data, and firmware on the card will be saved to flash along with the strategy. If you want only the strategy saved,
delete configuration and firmware files from the card.
1. In PAC Control Configure mode, choose File >

Strategy Options. Click the Download tab.
2. If you want to set the strategy to autorun, check the box Set autorun flag after download.
Autorun works if you insert the card and then turn on the controller; it has no effect if you insert the card
when the controller is already turned on. (If the controller is already turned on, the new strategy follows
the status of the existing strategy: if the existing strategy was running when the card was inserted, the
new strategy will run; otherwise, it will not.)
If you use background downloading, the controller will switch to the new strategy when the card is
inserted.
3. Click OK.
4. Choose one of the following:
a.
If you’re using PAC Terminal Secure Strategy Distribution (SSD), follow the steps in PAC Terminal SSD
Technical Note (form 1762, available with purchase of PAC Terminal SSD ) to create a download file
with the file extension .ssd.
b.
Otherwise, compile the strategy as a Control Engine Download file (.cdf ) by right-clicking the name
of the control engine in the Strategy Tree and choosing Compile Control Engine Download File from
the pop-up menu.
The file is created in the same folder as the strategy, with a .cdf extension and a filename consisting
of the strategy’s name and the control engine’s name (for example, MyStrategy.MyEngine.cdf ).
5. (Firmware below 9.4a only): Rename the .cdf or .ssd strategy file to fit the 8 dot 3 filename format for the
microSD card (see
“Card Type and Format” on page 44 ).
