Chapter 4: Using Your Output Module 27
The first 8 status bits reflect the settings in the channel configuration
word. The remaining status bits flag the various errors that the module
can detect.
Output Data Limiting Enabled (status bit 8)
This bit is set to one whenever output data limiting is properly enabled.
To properly enable output data limiting, the low and high output limits
(output words 6 and 7, respectively) musts be non-zero and non-equal,
and the low limit (output word 6) must be lower than the high limit
(output word 7). See Optional: Setting The Output Data Limits (or User-
Defined Scale), earlier in this chapter, for more information.
Operating Temperature Error (status bit 9)
This bit is set to one whenever the operating temperature exceeds the
specified range (0 to 60 ˚C). This bit is reset to zero when the operating
temperature returns to the specified range.
Over-Limit Error (status bit 10)
This bit is set to one whenever the output data meets or attempts to
exceed the output data limit in output word 7, if output data limiting is
properly enabled. This bit is reset to zero when the output data falls
below the output data limit in output word 7.
Under-Limit Error (status bit 11)
This bit is set to one whenever the output data meets or attempts to
exceed the output data limit in output word 6, if output data limiting is
properly enabled. This bit is reset to zero when the output data rises
above the output data limit in output word 6.
Over-Range Error (status bit 12)
This bit is set to one whenever the output data meets or attempts to
exceed the maximum count limit defined by the data format and output
range selected (see Table 11). This bit is reset to zero when the output
data falls below the maximum count limit.
Under-Range Error (status bit 13)
This bit is set to one whenever the output data meets or attempts to
exceed the minimum count limit defined by the data format and output
range selected (see Table 11). This bit is reset to zero when the output
data rises above the minimum count limit.
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 or an operating
temperature error (see above), or while the SLC 500 processor is
resetting. This bit is reset to zero when the error no longer exists.
