Manual 26659
ProAct P-Series FL Position Controller
Woodward
77
The ProAct P-Series FL only monitors the ‘Current Data Link’ bits of DM13 (bits
8-7 in byte 1) for Start/Stop commands and support for the DM13 ‘Suspend’
feature is not provided. A 'Start' command is a value of 01 on bits 6-7 of byte 1, a
'Stop' command is a value of 00 on bits 6-7 of byte 1, and a 'Hold' command is a
value of 00 or 01 on bits 4-7 of byte 4.
While a DM13 commanded 'stop' is active, the CAN demand is internally set to
zero and any CAN demand timeout will not be recorded. The commands shall be
processed as follows in the event multiple commands are determined in the
same message. When in QUIET/Stop mode, a Start shall have priority over a
Hold and additional Stop commands are ignored. When not in QUIET/Stop
mode, Start and Hold commands are ignored.
