IDN 410 (S-0-0410) Probe 1 Negative Edge Latched Status

Indicates whether captured position data has been latched within IDN 131 after the falling edge of the probe 1 input signal ( IDN 401 ).

Position data can only be latched on the negative edge of probe 1 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 1. Additionally, probe 1 must be armed by setting the „Probe 1 Enable“ ( IDN 405 ).

After arming probe 1, the next probe 1 falling edge will capture the current position and the „probe 1 negative edge latched status“ will set when the captured data is available in IDN 131 .

Once the latched status has been set, no more position captures will occur on the falling edges of the probe 1 input until the master re-arms probe 1 by clearing and setting the probe 1 enable. Clearing the probe 1 enable signal will reset the latch status.

IDN 410 duplicates information found in the probe status ( IDN 179 , bit 1). IDN 410 may be assigned to a RTS bit (AT status word bit 6 or 7) through IDN 305 or IDN 307 .
