IDN 412 (S-0-0412) Probe 2 Negative Edge Latched Status
Indicates whether captured position data has been latched within IDN 133 after the falling edge of the probe 2 input signal ( IDN 402 ). Position data can only be latched on the negative edge of probe 2 if the probing procedure ( IDN 170 ) is active and the „Probe Control Parameter“ ( IDN 169 ) has been configured to use the negative edge of probe 2. Additionally, probe 2 must be armed by setting the „Probe 2 Enable“ ( IDN 406 ). After arming probe 2, the next probe 2 falling edge will capture the current position and the „probe 2 negative edge latched status“ will set when the captured data is available in IDN 133 .
Once the latched status has been set, no more position captures will occur on the falling edges of the probe 2 input until the master re-arms probe 2 by clearing and setting the probe 2 enable. Clearing the probe 2 enable signal will reset the latch status.
IDN 412 duplicates information found in the probe status ( IDN 179 , bit 3). IDN 412 may be assigned to a RTS bit (AT status word bit 6 or 7) through IDN 305 or IDN 307 .
