Description
Minimum time interval specified by the manufacturer for writing copies
of NV parameters to non-volatile memory. Zero means it will never be
automatically copied. At the end of NV_CYCLE_T, only those parameters
which have changed need to be updated in NVRAM.
Percent of memory available for further configuration. Zero in a pre-
configured device.
Percent of the block processing time that is free to process additional
blocks.
Time duration at which to give up on computer writes to function block
RCas locations. Shed from RCas shall never happen when SHED_ROUT =
0
Time duration at which to give up on computer writes to function block
ROut locations. Shed from ROut shall never happen when SHED_ROUT =
0
Condition set by loss of communication to an output block, fault
promoted to an output block or physical contact. When FAIL_SAFE
condition is set, then output function blocks will perform their FAIL_SAFE
actions.
Allows the FAIL_SAFE condition to be manually initiated by selecting Set.
Writing a Clear to this parameter will clear the device FAIL_SAFE if the
field condition has cleared.
Maximum number of unconfirmed notify messages possible.
Maximum number of unconfirmed alert notify messages allowed.
The time the resource will wait for confirmation of receipt of a report
before trying again. Retry will not happen when CONFIRM_TIME=0.
When hardware write protection is selected, WRITE_LOCK becomes an
indicator of the jumper setting and is unavailable for software write
protection.
When software write lock is selected, and WRITE_LOCK is set, no writings
from anywhere else are allowed, except to clear WRITE_LOCK. Block
input will continue to be updated.
This alert is generated by any change to the static data.
The block alarm is used for all configuration, hardware, connection
failure or system problems in the block. The cause of the alarm is entered
in the subcode field. The first alarm to become active will set the Active
status in the Status parameter. As soon as the Unreported status is
cleared by the alarm reporting task, another block alarm may be
reported without clearing the Active status, if the subcode has changed.
The current alarm status, unacknowledged states, unreported states,
and disabled states of the alarms associated with the function block.
Selection of whether alarms associated with the function block will be
automatically acknowledged.
