Over-Range Error (status bit 12)
This bit is set to one whenever your module detects an over-range condition for a
configured channel. An over-range condition exists when the input value is very
near or above the upper limit for that channel’s data format (see Table 14).
Under-Range Error (status bit 13)
This bit is set to one whenever your module detects an under-range condition for
a configured channel. An under-range condition exists when the input value is
very near or below the lower limit for that channel’s data format (see Table 14).
Non-Fatal Channel Error (status bit 14)
This bit is set to one whenever your module detects a recoverable channel error,
such as an invalid configuration word for that channel. This bit is reset to zero
when the error is resolved.
Fatal Channel Error (status bit 15)
This bit is set to one whenever your module detects a “non-recoverable” channel
error, such as a software power-up failure due to corrupt hardware or
malfunctioning software. You may be able to recover from this type of error by
resetting the SLC 500 processor or cycling power to your module.
