官方故障排除步驟

Parameters: %1 = Channel ID %2 = Channel ID Definitions: This channel defines a WAIT marker with other channels, which on their part have no correspondence with this wait marker. This channel's WAIT marker has no explicit counterpart in the other channel; i.e. the channels do not mutually wait. ============================================================ Example Ch 3Ch 5Ch 7 WAITM(99,3,5) WAITM(99,3,5) WAITM(99,5,7) The wait markers in channels 3 and 5 mutually wait for each other and channel 7 only waits for channel 5. Therefore, channel 7 may continue when 5 and 7 have reached the wait marker, but channel 3 is still far in front of the wait marker. When it continues, channel 7 deletes its wait marker. When wait marker 99 is reached again, you can no longer determine the behavior precisely. ============================================================ Reaction: Alarm display. Remedy: In each wait marker, list all channels with which y ou want to synchronize, or suppress the alarm with MD11410 $MN_SUPPRESS_ALARM_MASK, bit 23. ============================================================ Sample solution A: Ch 3Ch 5Ch 7 WAITM(99,3,5,7) WAITM(99,3,5,7) WAITM(99,3,5,7) ============================================================ Sample solution B: Ch 3Ch 5Ch 7 WAITM(99,3,5) WAITM(99,3,5) WAITM(88,5,7) WAITM(88,5,7) ============================================================ Sample solution C: Ch 3Ch 5Ch 7 WAITM(88,5,7) WAITM(88,5,7) WAITM(99,3,5) WAITM(99,3,5) Program Continuation: Clear alarm with the Delete key or NC START.
