Descriptions
The value and status
required by the BKCAL_IN
input of another block to
prevent reset windup and
to provide bumpless
transfer of closed loop
control.
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
parameter. 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.
This parameter reflects
the error status
associated with the
hardware or software
components associated
with a block. It is a bit
string so that multiple
errors may be shown.
Used to override the
calculation of the block.
When enabled, the SP is
sent directly to the
output.
The remote setpoint
value from another block.
Allows you to specify
control strategy options.
The supported control
options for the PID block
are Track enable, Track in
Manual, SP-PV Track In
Man, SP-PV Track In LO or
IMAN, Use PV for BCKAL
OUT, and Direct Acting.
