Under normal conditions, the output statuses (OUT_D and BKCAL_OUT_D) are Good: Cascade. However, the block supports a status action on failure and block error indications.
Action on failure
When the output hardware goes bad, the OUT_D and BKCAL_OUT_D statuses are set to Bad: DeviceFail. The BLOCK_ERR parameter shows Output failure. When SIMULATE_D is enabled, OUT_D does not show Bad status.
When there is no DST assigned to the IO_READBACK parameter, PV_D status is set to Bad and the BLOCK_ERR parameter shows Bad PV.
When the input hardware used for IO_READBACK goes bad, BLOCK_ERR shows Bad PV and Readback failed. In this case, the status of READBACK_D and PV_D is Bad: DeviceFail.
