FAULT_STATE, SET_FSTATE, CLR_FSTATE: these only apply to output function blocks. (The Model 2xx has no output function blocks).
MAX_NOTIFY: the maximum number of alert reports that the transmitter can send without getting a confirmation.
The user can set the number low, to control alert flooding, by adjusting the LIM_NOTIFY parameter value.
LIM_NOTIFY: the maximum numbers of unconfirmed alert notify messages allowed. No alerts are reported if set to zero.
CONFIRM_TIME: the time that the transmitter will wait for confirmation of receipt of a report before trying again. Retry will not occur if CONFIRM_TIME = 0.
WRITE_LOCK: When set to LOCKED, will prevent any external change to the static or
UPDATE_EVT (Update Event): is an alert generated by a write to the static data in the block.
BLOCK_ALM (Block Alarm): is used for configuration, hardware, connection, or system problems in the block. The cause of any specific 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 sub- code has changed.
ALARM_SUM (Alarm Summary): contains the current alert status, the unacknowledged states, the unreported states, and the disabled states of the alarms associated with the block.
ACK_OPTION (Acknowledge Option): selects whether alarms associated with the block will be automatically acknowledged.
WRITE_PRI (Write Priority): the priority of the alarm generated by clearing the write lock.
WRITE ALM (Write Alarm): the alert generated if the write lock parameter is cleared.
ITK_VER (ITK Version): contains the version of the Interoperability Test Kit (ITK) used by the Fieldbus Foundation during their interoperability testing.
