4.5 Acyclic data
For normal variable frequency drive operation the acyclic data is not required.
This section therefore addresses programming experts.
4.5.1 Introduction
Acyclical communications are used to read and write parameters and
diagnostic data in the variable frequency drive/variable speed starter;
they can take place at the same time as cyclical data is being transferred.
This means that acyclical communications are independent from the
selected profile.
In this case, the SmartWire-DT coordinator (client) communicates acyclically
with the variable frequency drive/variable speed starter. Communications are
always initiated by the client.
→
In order for acyclic data to be transmitted and diagnostic
activities to be performed, the higher-level PLC must feature
acyclic services.
The programmable EASY802-DC-SWD and EASY806-DC-SWD
switchgear and controlgear do not feature acyclic services!
