groov I/O: TPO may not update percent on-time (duty) correctly


Applies To:

Firmware for GRV-EPIC-PR1

Versions Affected:

All versions prior to 1.4.3

Resolved In Version:

1.4.3


Symptoms:

If your PAC Control strategy runs a Set TPO Period command followed by Set TPO Percent command, you may observe that the TPO period is cut short or extended for one period. This should not happen; any changes to the cycle should take effect at the boundary of a period so as not to cut short or extend a period.

Note: To resolve this issue, you must also apply updated firmware to some groov output modules as described in KB88434.

Resolution:

Opto 22 has resolved this issue.
