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
In the functions "Always OFF", "Always ON" and "Button-press display", the status LED
indicates an active value change when the value of the corresponding button is changed.
The status LED is then switched off and will then light up for approx. 250 ms whenever a
new value is transmitted.
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
Configuration example:
-
Value transmitter 1-byte (all other value transmitters identical)
-
Function = value transmitter 0…255
-
Value configured in the ETS (0...255) = 227
-
Step width (1...10) = 5
-
Start on value adjustment = same as configured value
-
Direction of value adjustment = toggling (alternating)
-
Time between two telegrams = 0.5 s
Example 1: Value adjustment with overflow? = No

Example 2: Value adjustment with overflow? = Yes
