3.7 Acyclic data

3.7.1 Acyclical read data

In addition to cyclical input and output bytes, EMS-DOS/ROS-SWD electronic
motor starters make it possible to read from and write to the acyclical objects
listed below:
The required object is addressed with parameters ID and Index. The input
address of the SmartWire-DT module with which communication is to be
established is set with parameter "ID".
The Index parameter is used to assign the object an address. The first object
will be assigned number 1, the second number 2, etc. In PKE-SWD devices,
object 1 will return current value I-REL, for example.
