Function
Limit value lower
Limit value upper
0...255
0
255
0...100 %
0 % (value = 0)
100 % (value = 255)
Value range limits for the different value transmitter functions
i
During a value adjustment, the newly adjusted values are only in the volatile RAM memory
of the extension module. Therefore, the stored values are replaced by the preset values
programmed in the ETS when a reset occurs (bus voltage failure or ETS programming).
i
With the 1-byte value transmitter in the "Value transmitter 0…100 %" function, the step
width of the adjustment will also be indicated in "%". If the starting value of the
communication object is used, it may happen in this case during value adjustment that the
value last received via the object must be rounded and adapted before a new value can be
calculated on the basis of the step width and transmitted. Due to the computation
procedure used, the new calculation of the value may be slightly inaccurate.
Value adjustment examples...
-
Function = Value transmitter 0…255 ("Value transmitter 0…100 %" is basically the same)
-
Value configured in the ETS (0...255) = 247
-
The rotation angle for value adjustment = approx. 36° (3 notches)
-
Step width (1...10) = 5
-
Start on value adjustment = same as value after last adjustment
-
Direction of value adjustment = clockwise: upwards / anticlockwise: downwards
