7.4.4 Advancement on Drive State Conditions
Figure 19 shows how the Seq Count parameter is bit-packed with drive state conditions when the state
duration bits are programmed to 1010 and 1011. If the AND (1010) configuration is selected, then all bits
set in the count parameter must have the corresponding drive state occur for advancement to the next
1000
Low Analog Pulse Threshold (Vin1) - The active sequencer state lasts until the current signal
applied to Vin1 terminals is less than a value programmed in “Seq Count X.” The value
programmed in “Seq Count X” should be the percentage of input after span and offset are
applied (where 100.00% = 10000).
Note: The % of analog input after span and offset can be read in
1001
High Analog Pulse Threshold (Vin1) - The active sequencer state lasts until the current signal
applied to Vin1 terminals is less than a value programmed in “Seq Count X.” The value
programmed in “Seq Count X” should be the percentage of input after span and offset are
applied (where 100.00% = 10000).
Note: The % of analog input after span and offset can be read in
1010
Drive State (AND) - With this selection, the count parameter represents a bit-packed status
word corresponding to drive state conditions. The format of this status word is documented in
“Advancement on Drive State Conditions” on page 104. The Sequencer will advance if all of
the drive conditions are met that are enabled in the count parameter.
1011
Drive State (OR) - With this selection, the count parameter represents a bit-packed status
word corresponding to drive state conditions. The format of this status word is documented in
“Advancement on Drive State Conditions” on page 104. The Sequencer will advance if any of
the drive conditions are met that are enabled in the count parameter.
1100
Encoder Home Pulse - The active sequencer state lasts until the number of pulses
programmed into “Seq Count X” is detected on the Encoder Home Input C+, C-. This allows
advancement on process revolutions.
1101 1110 1111
The sequencer will never advance if these options are selected.
