6.5
RTPERIOD—The time period between runs of a scheduled ACP, in format HH:MM:SS.
Minimum period is 10 seconds; maximum period is 24 hours. Not used if ACT_TYPE is
DEMAND only.
RUN_INIT—When ON, tells the CG scheduler to turn on the ACP immediately after
completing an initialization event (see note on this page).
STIME—The first time of day that a periodic program runs, in format HH:MM:SS (eight
ASCII characters). The maximum time is 24:00:00. Not used if ACT_TYPE is CYCLIC,
CYC_DMD, or DEMAND.
TAKE_I_P—When ON, informs the attached ACP to take its initialize path. Set ON at any
initialization event (see note on this page). Also can be set ON by CL programs and ACPs.
UNIT—Unit identification number.
NOTE
The three types of initialization event are: CG power up and software load (cold restart); host
processor initialization or data-link restart (warm restart); and individual ACIDP initialization
(connecting it to an ACP or removing abort condition by operator action).
6.5 DATA LINK STATUS INFORMATION
The CG holds data link status information in its Processor Status data point. To view this
data, place the point $PRSTSnn (where nn is the CG's node number) in a custom
schematic display. The three data link status parameters of this point and their value
meanings are:
ULP_STS = IN_SERV—Communications with the host computer have been established.
This value is set when Restart is complete.
= FAILED—Communications with the host computer are broken. This value
is set when both links have failed.
DL1_STS = IN_SERV—Link 1 has been connected and the CG is using or trying to use
the link.
= FAILED—The CG has disconnected Link 1 because of problems.
DL2_STS = IN_SERV—Link 1 has been connected and the CG is using or trying to use
the link.
= FAILED—The CG has disconnected Link 2 because of problems.
= NOT_INST—The CG has been configured for operation on Link 1 only.
