Embedded I/O Chapter 3
Local:4:I.InvalidRangeLimitX This error status bit indicates that either the high or low limit values (or both) set for
the range in output array tags Range0to3[X]HiLimOrDirWr and/or
Range0to3[X]LowLimit are invalid.
The output arrays sent with this error are not processed and these bits are set until
an output array without the error is received by the embedded HSC.
Local:4:I.RangeXActive This bit indicates whether a range is active based on your configuration of the
range.
If the current count meets the configuration parameters of the range, the
corresponding RangeXActive tag is set to 1.
Local:4:I.CtrXCurrentCount This 32-bit tag contains the current count value of counter X.
Local:4:I.CtrXStoredCount This 32-bit tag contains the last stored count value of counter X. Stored count
values are triggered based upon your configuration of this function.
Local:4:I.CtrXStatus This tag contains the status and individual error flags for counter X.
Local:4:I.CtrXOverflow Depending on the counter mode you configured, this tag indicates one of the
following:
•
For a linear counter, that counter X is, or has been in, an overflow condition.
•
For a ring counter, it indicates that counter X has rolled over while counting up.
If an overflow occurs, this bit is latched. It must be unlatched via the CtrControlBits
tag in the output array.
Local:4:I.CtrXUnderflow Depending on the counter mode you configured, this tag indicates one of the
following:
•
For a linear counter, counter X is, or has been in, an underflow condition.
•
For a ring counter, counter X has rolled over while counting down.
If an underflow occurs, this bit is latched. It must be unlatched via the
CtrControlBits tag in the output array.
Local:4:I.CtrXRisingEdgeZ This tag indicates that the Z input for counter X has had a rising edge occur. This bit
is set to 1 and latched on a rising edge of the Z input signal. It must be cleared to 0
by using the CtrResetRisingEdgeZ bit of CtrControlBits tag in the output array.
Local:4:I.CtrXInvalidDirectWrite This tag indicates that an invalid value has been written during a direct write
attempt to the Range0to3[X]HiLimOrDirWr tag for counter X when the
Range0to3[X]LoadDirectWrite bit (within the Range0to3[X]ConfigFlags tag)
transitions from 0 to 1.
Local:4:I.CtrXInvalidCounter
(1) This tag bit indicates that one or more counter control bits for counter X (in the
output array CtrControlBits tag) are set when the number of counters was
configured at less than X+1.
Local:4:I.CtrXPresetWarning This tag indicates that the embedded HSC has independently set counter X to the
counter X preset value. This PresetWarning tag is set when one of the following
occurs:
•
a configuration is sent to the embedded HSC where the counter minimum value
is greater than the current count value.
•
a configuration is sent to the embedded HSC where the counter maximum value
is less than the current count value.
Local:4:O Output data and status tags for the HSC counters.
