39 TRK_VAL This input is used as the track value when external tracking is
enabled by TRK_IN_D.
TRK
40 FF_VAL The feed forward value and status. FF
41 FF_SCALE The feedforward input high and low scale values, engineering
units code, and number of digits to the right of the decimal
point.
0-100% FF
42 FF_GAIN The gain that the feed forward input is multiplied by before it
is added to the calculated control output.
0
43 UPDATE_EVT This alert is generated by any change to the static data.
44 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.
45 ALARM_SUM The current alert status, unacknowledged states, unreported
states, and disabled states of the alarms associated with the
function block.
46 ACK_OPTION Selection of whether alarms associated with the block will be
automatically acknowledged.
0: Auto Ack Disabled
1: Auto Ack Enabled
