Writing cyclic values to the process image
The source for values that are written cyclically to the process image depends on the setting at
input parameter
SelStrInputs
:
●
SelStrInputs
=
FALSE
(default): The values and signal states for the I/O outputs are
transferred from output structure CyclData.Output which is interconnected with visualization
block Mag6T.
●
SelStrInputs
=
TRUE
: The values and signal states for the I/O outputs are transferred
from the
SetTot1/2, ModeTot1/2, DCtr, DSetP, DComp
inputs and their signal
states to the device.
Retain last values if I/O values are invalid
The block retains the last valid values if invalid I/O values were found (inputs <> 16#80xxxxxx
or
RackF
=
TRUE
).
Signal state for process values
The signal state of process values (output structure
CyclicData
.
Inputs
) is derived from the
higher-level error, or from the signal state returned by MAG6000. In the case of higher-level
errors such as rack failure (inputs Mode <> 16#80xxxxxx or
RackF
=
TRUE
), status (.ST) 16#00
is output and otherwise the value provided by MAG6000.
Simulating signals
The block does not have a function for simulating process values.

Error handling of FbMag6T
Error handling of FbMag6T
The following errors can be displayed for this block:
● Higher-level error
● Module errors
Higher-level error
Higher-level errors are indicated by the value 1 at output parameter
QRackF
if the signal state
in the HighWord of input parameter
Mode
changes to a value other than 16#80 , or if
input
RackF
is set.
The
CyclData.Csf
output is set in addition, and the signal status 16#00 output in the output
parameters
Input.VolFlow.ST
,
Input.Tot1VF.ST
and
Input.Tot2VF.ST
as well as
at the outputs
QCVolFlow, QCTot1VF
and
QCTot2VF
.
