You can simulate the following values:
● Position feedback (
SimRbk
,
SimRbkLi
)
Tracking and limiting a manipulated variable
You can correct the manipulated variable output to the tracking value
MV_Trk
or the
manipulated variable feedback Rbk to realize bumpless switchover. To track the manipulated
variable output, you have to set the parameter
MV_TrkOn
= 1.
If the parameter
MV_TrkRbk
= 0, the manipulated variable output is corrected to the tracking
value
MV_Trk
. The manipulated variable output
MV
is limited to the
MV_HiLim
and
MV_LoLim
parameters.
If the parameter
MV_TrkRbk
= 1, the manipulated variable output is tracked to the position
feedback
Rbk
. There are no limits here.
The "Tracking" text is displayed additionally in the standard view of the faceplate.
Tracking has a higher priority than interlock for a control valve.
Forming the group status for interlocks
This block provides the standard "Form group status for interlock information" function that is
described in the APL Online Help.
Forming the signal status for blocks
This block provides the standard "Form and output signal status for technological blocks"
function that is described in the APL Online Help.
The signal status of the output for the manipulated variable feedback
RbkOut
always
corresponds to the signal status of the
Rbk
input or, when the block is in simulation, the signal
status of the 16#60output.
The signal status of the
FbkCloseOut
and
FbkOpenOut
outputs is fetched and sent from the
worst signal status from the
RbkOut
output and the corresponding feedback signal inputs
FbkClose
and
FbkOpen
.
The signal status of the manipulated variable output
MV
always corresponds to the signal status
of the input parameter
MV_Ext
or
MV_Int
, depending on how the setpoint is specified. If the
internal manipulated variable
MV_Int
is used, the signal status 16#80 is always output.
The signal status of manipulated variable difference
ER
is fetched and sent from the worst
signal status of the two outputs
RbkOut
and
MV
.
The worst signal status
ST_Worst
for the block is formed from the following parameters:
●
FbkOpenOut.ST
●
FbkCloseOut.ST
●
FbkAuxVOpenOut.ST
●
FbkAuxVCloseOut.ST
●
RbkOut.ST
●
LocalLi.ST
