Please check the correct IP address of the device and change the value if necessary.
In this example we have the 192.168.1.86 as the IP address for the DAC-4x(A)
10.4.4 CMD 3, Reading values from one DAC-4x(A) node
The DAC-4x(A) connected to the Profinet has a fix SNUM (slave number). Together with this number it is possible to read
a set of parameter of this device.
The parameter-ID’s are shown in table □ Chapter “11 List of parameters“, page 64
An reading access is done as followed:
• The predefined slave number SNUM for the DAC4x(A) is 1.
For slave 1 #SNUM := 1;.
• Setup the CMD: # CMD := 3;
• Write the starting address of the first parameter ID which should be read by the structure
E.g. parameter 22, S1.01 #IN_CMD3.PAR_ID := 22;
• Define the number of parameters to be read (maximum 8).
E.g. 4 parameters S1.01..S1.04 #IN_CMD3.PAR_N := 4;
• Definition of the states in #CMD3_STAT:
0: no action
1: Start of reading
