• Timeout
  • Amount of time the module waits for a response from the device. Value is in milliseconds; minimum timeout: 250 msec; no maximum. If your network is lossy or has high latency, you may want to increase the timeout value.
• Data Scan Rate
  • Controls the poll rate (that is, how often the module scans the device).
  • Note: When reading large amounts of data, increase the number of milliseconds to allow more time for reads.

Step 6

Click Create New Device. The Devices webpage opens.
Make sure that Enabled is "true"
Wait until the Status is "Connected" (This may several seconds, depending on the source and number of tags.)

Get Tags from the Opto 22 Device

The Opto 22 SNAP PAC Driver module can:

• Scan all tags (Simple to use; lower performance as all tags are scanned.)
• Scan specific tags (Requires setup in PAC Control; offers best performance since only the tags you need are scanned. For details, see Scanning Specific Tags.)

There are two ways to browse all tags:

• From Ignition's Configure tab
  • Select OPC Connections > Quick Client, and then expand the folders to find the tags from the Opto 22 device's tags.
