3.4 Acyclic communication
3.4.1 General information about acyclic communication
With acyclic communication, as opposed to cyclic communication, data transfer takes place
only when an explicit request is made (e.g. in order to read and write parameters).
The "Read data record" and "Write data record" services are available for acyclic
communication.
