6.4 ACIDP/CRDP PARAMETER DESCRIPTIONS
The following are brief descriptions of the ACIDP and CRDP parameters that are visible
through a Universal Station's standard displays. For details of all CG parameters, see the
Computer Gateway Parameter Reference Dictionary.
ABORTCOD—Four ASCII characters indicating the reason for termination of ACP
execution by the host processor. The value 0000 (zeros) is used to designate a normal
ACP termination. Other value assignments are defined by the host processor. See
EXECSTAT for display information.
ACCESSKEY—Determines whether or not the ACP can execute writes to the LCN. Values
are READWRIT or READONLY.
ACPROG—The file name of the ACP as identified within the host processor.
ACT_TYPE—The activation method for the associated ACP. Values are CYCLIC,
PERIODIC, CYC_DMD, PER_DMD, or DEMAND.
CONF_RQD—Set ON when an operator message requiring confirmation is sent. Must be
true before a message confirmation is processed.
CONFWAIT—Time (in seconds) remaining before a pending message confirmation will time
out.
EXECSTAT—The present execution state of the ACP. Values are ABORT, ACCESS,
DELAY, OFF, RUN, WAIT, FAIL. When the execution state is ABORT, the ACIDP's
Detail Display shows the ABORTCOD value instead.
INH_STAT—An operator-changeable parameter that blocks CG Turn On of the attached
ACP. Values are INHIBIT or PERMIT.
KEYWORD—Name shown on Universal Station displays.
NAME—Name of the ACIDP/CRDP.
NEXT_RTM—Next runtime, used by both Periodic and Cyclic activation. The parameter is
in form HH:MM:SSbMM:DD:YYb (where "b" indicates a space). Blank if activation type
is DEMAND only.
OPER_DMD—An operator-accessible parameter, which when set ON turns on the ACP,
but only if the ACT
_TYPE value for the ACDIP is either CYC_DMD, PER_DMD, or
DEMAND, and ABORTCOD value is zero (see the Computer Gateway Parameter
Reference Dictionary for effect of OPER_DMD on an Aborted ACP).
PPS—When ON, results in activation of the attached ACP. It can be set ON by an event
from the HG or AM, or by a CL/AM program, or an ACP.
PROGSTAT—Installation status of the ACP. Values are NOT_INST, TEST, RESTRICT,
NORMAL.
PTDESC—Description of the variable.
RCASENB—Determines whether or not the ACP can execute continuous control by
executing SP/OP stores to the LCN. Values are ON and OFF.
