IDN 409 (S-0-0409) Probe 1 Positive Edge Latched Status

Indicates whether captured position data has been latched within IDN 130 after the rising edge of the probe 1 input signal ( IDN 401 ). Position data can only be latched on the positive 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 positive 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 rising edge will capture the current position and the „probe 1 positive edge latched status“ will set when the captured data is available in IDN 130 .

Once the latched status has been set, no more position captures will occur on the rising 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 409 duplicates information found in the probe status ( IDN 179 , bit 0). IDN 409 may be assigned to a RTS bit (AT status word bit 6 or 7) through IDN 305 or IDN 307 .
