Performing a Scan
Once you set up a scan list and configure the scan, the actual scan can be
performed.
•
If a scan list contains a non-existing channel, the scan cannot be
performed and an error will occur.
•
If a scan list contains a channel on a digital I/O module that does not
work in Mode #1 or Mode #2, the scan cannot be performed and an
error will occur (see page 86 for more information about modes).
•
If a stored channel setup in the scan list does not match the current
hardware configuration, the scan cannot be performed and an error
will occur.
•
Front-Panel Operation: Press Scan to begin the scan operation.
Stop a scan in progress by pressing Shift+Scan. The last channel
closed in the scan list will remain closed. You cannot pause and then
continue a scan. You must start the scan operation over.
Press Step to start and step through the channels in the scan list, one
channel at a time.
•
Remote Interface Operation: Use the STEP command to begin a scan.
If you abort a scan in progress, the last channel closed in the scan list
will remain closed. You cannot pause and then continue a scan. You
must start the scan operation over.
