Mode Explanation
25 1025 FREE_TIME 0 – Percent of the block processing time that is free to process
additional blocks. EXA does not support this.
26 1026 SHED_RCAS 640000 (2S) AUTO Time duration at which to give up on computer writes to function
block RCas locations. Supported only with PID function.
27 1027 SHED_ROUT 640000 (2S) AUTO Time duration at which to give up on computer writes to function
block ROut locations. Supported only with PID function.
28 1028 FAULT_STATE 1 – Condition set by loss of communication to an output block, failure
promoted to an output block or a physical contact. When fail-safe
condition is set, Then output function blocks will perform their
FSAFE actions.
29 1029 SET_FSTATE 1 AUTO Allows the fail-safe condition to be manually initiated by selecting Set.
30 1030 CLR_FSTATE 1 AUTO Writing a Clear to this parameter will clear the device fail-safe
state if the field condition, if any, has cleared.
31 1031 MAX_NOTIFY 3 – Maximum number of unconfirmed notify messages possible.
32 1032 LIM_NOTIFY 3 AUTO Maximum number of unconfirmed alert notify messages allowed.
33 1033 CONFIRM_TIM 640000 (2S) AUTO The minimum time between retries of alert reports.
34 1034 WRITE_LOCK Not locked AUTO If set, no writes from anywhere are allowed, except to clear
WRITE_LOCK. Block inputs will continue to be updated
35 1035 UPDATE_EVT – – This alert is generated by any change to the static data.
36 1036 BLOCK_ALM – – The block alarm is used for all configuration, hardware,
connection failure or system problems in the block. The cause of
the alert is entered in the subcode field. The first alert to become
active will set the Active status in the Status attribute.
As soon as the Unreported status is cleared by the alert
reporting task, another block alert may be reported without
clearing the Active status, if the subcode has changed.
37 1037 ALARM_SUM Enable – The current alert status, unacknowledged states, unreported
states, and disabled states of the alarms associated with the
function block.
38 1038 ACK_OPTION 0xFFFF AUTO
39 1039 WRITE_PRI 0 AUTO Priority of the alarm generated by clearing the write lock.
40 1040 WRITE_ALM – – This alert is generated if the write lock parameter is cleared.
41 1041 ITK_VER 4 – Version number of interoperability test by Fieldbus Foundation
applied to EXA.
42 1042 SOFT_REV – EXA software revision number.
43 1043 SOFT_DESC – Yokogawa internal use.
44 1044 SIM_ENABLE_
MSG
Null AUTO Software switch for simulation function.
