Table 9.B
Significance of channel status indicators
When the status indicator is: the scanner:
off is off line
green is on line, in run mode, and scanning
the racks in the scan list
blinking green is on line, in run mode, and scanning
only some of the racks in the scan list
red has an unrecoverable fault
blinking red has a recoverable fault
Table 9.C lists the error codes the scanner can write to the confirmation
status word in the control/status area for a scanner channel. The error code
uses the lower byte of the confirmation status word.
The scanner cannot generate any error codes that are not listed below. If
an error code shows up in the confirmation status word that is not listed
here, it is likely that another VME master processor accidentally wrote a
value into that word.
