Warning
If the physical value exceeds the defined value, a warning message is generat-
ed.
The value in coordinate
MB09 Averaging factor determines the smoothing of the
current. A setting between 0 and 0.99999 should be adjusted in consideration of the
following meaning:
0 (minimum) = smoothing deactivated
1 (maximum) = infinite smoothing.
The operating mode for the error case is defined in coordinate
MB11 Operation if
fault . If the physical variable to be output leaves the figure range, the current output
current is increased or decreased by the value adjusted in MB12 Rise/decr.w.fault .
It is possible to output a constant current (
MB14 Test current ) independently of a
measurement for testing purposes. The desired value is entered in the test current
parameter and activated in operating mode.
The output of the current can take place according to 3 methods in
MB17 Method .
slow
Output method for printers or displays, etc.
The output current is updated and held for one second every full
second. The output current includes digital stages.
quick
Output method for regulation.
The output current is calculated with each recalculation of the
physical output value. The frequency of recalculation can be
read under
FD01 Cycle duration . The output current follows the
physical output value directly in the scope of the conversion
speed. It is held until a new output value is provided. The output
current includes digital stages.
linear sweep
Output method which can be used if a downstream regulator
reaction is oversensitive to digital stages, but can circumvent
them with a constant dead time of one second.
A new current output value is calculated every full second. Then,
the current output is set to the new value, but not immediately
(stage); it takes place in 100 increments of 10 milliseconds
each, starting from the last value, on a continuous ramp. The
output current is smooth, but delayed one second.
