6.1.3 Assembly object 0x4
The assembly object is used to group input or output data in order to be able
to easily read and write large volumes of data using a single connection. The
output data to all SmartWire-DT modules is grouped in instance 100. The
inputs of all SmartWire-DT modules are grouped in instance 101. The object
length varies and depends on the number of SmartWire-DT modules and
their data volumes. The maximum object length is 496 bytes for each
instance.
