Click here for troubleshooting Using the Opto 22 SNAP PAC Driver Module tips.

The Driver module is designed to scan either:

• The tags you identify in a special stPublicListOfStrategyTags table, or
• All tags in the Opto 22 device.

For best performance, we strongly recommend you use the stPublicListOfStrategyTags table to get tags.

...

TIP: If you canít find a tag, check the following:
* The strategy is running in PAC Control.
* You correctly entered the tag name in the stPublicListOfStrategyTags table.
* After making changes to the table, you restarted the Driver module in Ignition and waited for its status to change to Connected.
For more information, see the Ignition Logs.

Scanning All Tags

If the Driver module canít find the stPublicListOfStrategyTags table in the strategy, it automatically retrieves the strategyís inventory of all driver-supported tags in their native format. This means that PAC Control's object inventory will not match Ignitionís object inventory. (For example, a 32-bit integer in PAC Control may be used as a number, a bitmask, and a zero/non-zero Boolean value.) For performance reasons, we strongly discourage scanning all tags.
