Profibus restart
Warm start With Warm start the Profibus stack is reset, compara-
ble with a power off/on.
Cold start With Cold start, all the parameters which are stored in
the Profibus stack as store parameters are reset to the
default value.
Profibus fail safe
Measured value The value of the Profibus function block comes after
the output value of the AO2000 function block.
Hold value The Profibus function block holds the last output value.
The display of the AO2000 function block may differ
from this.
Profibus meas. value
range
Physical The Profibus-AI value is the physical measured value for
AO2000.
VDI 4201 The physical measured values of AO2000 are scaled to
the range −10000 to 0 to +10000. 0 equals physically
zero and 10000 corresponds to the end value of the
indication range (according to VDI 4201).
