The flux-loop servo can be reset on a per-detector basis without having to stop the data-acquistion in progress. This is particulary useful in cases that only certain detectors are hit by cosmic rays.
To schedule a reset, a per-detector flag can be set using servo_rst_col# parameter and then the servo_rst_arm has to be set to 1.
The reset involves setting the integral-term of the calculated feedback to 0, resetting the corresponding flux-jump counter to 0, and resetting the corresponding integral_clamp flag.
For example to schedule a servo reset on col3, row 4, and col5, row 2:
wb rc1 servo_rst_col3 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 wb rc1 servo_rst_col5 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 wb rc1 servo_rst_arm 1
Bugs
- Currently (RC fw_rev 5.2.1 and 6.0.3), the per-pixel reset does not clear the filter, like a flx_lp_init does.
- Currently (RC fw_rev 5.2.1 and 6.0.3), resetting a given pixel also resets the pixel in the last column of the same row.
