4. For analog modules, the compiled hex value of the bit length is added.
For digital modules, the bits are added in byte blocks. A byte is completed
with leading zeros, if it is being fully used.
5. Individual values are separated by commas.
6. Closing bracket: "]".
7. Closing brace: "}".
The following examples illustrate the string structure for various modules:
Module
Input values
4AI module
4x 8-bit input values

30 dec, 40 dec)
2AI2AO module

(100 dec and
500 dec)
16DO module
Valve module, 2x
RawValues
The current output and input data can be retrieved as a collection with the vari-
ables RawValues. The RawValue output has been prepared for the best possible
performance in data transmission. The data is therefore not processed module-
specifically here. The recipient must assign the data to the modules personally
(see
g 4.2.4 Module
sequence). The data in this string is transmitted in the Big-
Endian format and hex-coded. Only the time stamp is decimal coded.
The following example illustrates the string structure for the module
M44,2AI2AO2M12-AE.

License number
The license number can be ordered with the number R412028478 and indication
of the serial number of the bus box (AesFieldbusNode->SerialNumber).
Enter license number
1. Enter the license number via OPC UA in the field MeasurmentFunctions -> Li-
censeKey.
2. Restart the product.
License is check when starting the product.

Notes
• The measurement functions required storing and computing time. The num-
ber of possible measurement functions is therefore limited to 30.
Each of these measurement functions occupies a so-called slot. To configure
them, there are several methods under the MeasurementFunctions object.
MeasurementFunctionBitConfig method
With the following input parameters, this method is used to configure the digital
functions.
