Since the configuration is not used, the length of the configuration assembly is specified
as 0. The device then operates with the default values. In this case, the acknowledge mode
is not used.
Below, examples of what data exchange looks like during two subsequent activations are
shown. Switching output 1 reflects the activation signal. Switching output 2 displays whether
the result is valid (status input/output I/O 2 = 1] or whether a NoRead has taken place (status
input/output
I/O 2 = 0).
