hello
I discovered the device and add some objects in it. In analog output object,i found a set of priorities in it.Using Analog_Output_Present_Value_Set() function,i have set a value in the network using the priority 14 and its done.but when i tried to overwrite it from the network,the priority went to 16 and writes into the last position of the Analog_Output_Level array,instead of overwriting it. So whenever the Analog_Output_Present_Value() function is being called,it breaks at the initially written value at 14 and didn't get the 16th priority value. How could am i able to write at the 14th priority position from the network?
