4 ARAMS Behavioral Requirements
This section specifies the behavior required for
ARAMS compliance.
13.8 ARAMS State Transitions — ARAMS compliance
requires that the equipment be capable of Transitions 1
through 11 in Table 1, with the exception of Transition
9. Transitions 12 and higher are optional.
4.1.1 Transition 9 is required only of equipment that
puts itself in a preventive maintenance mode based on
one or more internally monitored parameters, such as a
cycle counter. Transition 9 specifies that such a
transition takes place from STANDBY to
SCHEDULED DOWNTIME only. For equipment
without this feature, Transition 9 never occurs.
4.1.2 The equipment is required to provide the
capability to report to the host each time a state
transition occurs and to include data related to that
transition in these reports. Transition data included in
these reports allows the factory to calculate the amounts
of time spent in the different states.
4.1.3 At all transitions except Transition 10, when a
manufacturing state is specified, and Transition 11, the
current value of ARAMSState is stored in
PrevARAMSState and the ARAMS Substate Code
specified is then stored in ARAMSState. A user
selection of a specific manufacturing state is discussed
in Section 16.5 below.
4.1.4 For all equipment-initiated transitions, except as
specified in Sections 16.5 and 16.6, the equipment shall
use an ARAMS Substate Code representing the default
for that state and shall not select a substate.
4.1.5 DowntimeAlarm and DowntimeAlarmText are
set only for equipment-initiated transitions to
SCHEDULED DOWNTIME and UNSCHEDULED
DOWNTIME. For all other transitions, these variables
are cleared.
4.1.6 If the equipment supports ARAMS accumulators
(Section 11.5), then the time spent in the previous state
is calculated and the appropriate accumulator is updated
at this time.
13.9 Powerup Entry — The ARAMS State Model
becomes active during or after initialization following a
powerup or reset when Transition 1 occurs. The state
entered at Transition 1 (the default entry state) depends
upon the ARAMS state that was last active before the
powerdown or reset occurred. This is determined by the
ARAMS Substate Code stored in ARAMSState
(Section 11.2.4). If this value is not a valid ARAMS
Substate Code as defined in Section 9.4, then the
default entry state is NON-SCHEDULED TIME.
4.1.7 At Transition 1, if the value in Powerdown-Time
does not represent a valid date and time, it shall be set
to a string of all zeroes. The value stored in
PowerdownTime is then stored in LastPowerdown to
preserve the estimate of the timestamp of the last
powerdown or reset. PowerdownTime is next set to the
current date and time, and periodic updating of Class 5
variables is enabled.
