17.4. Configuration of process data
To transmit process data via an I/O connection,
there is one static input and one static output assembly available. These assemblies contain selected attributes
combined into one object so that process data can be transmitted collectively via an I/O connection.
Access to process data cyclic or acyclic:
Cyclic access
In the connection variants "Polled I/O" and "Bitstrobed I/O", with "Change of state" (if input values change).
Acyclic access
via "Explicit Messages". The access path for acyclic access is:
class 4
instance "X" (X see in following table)
attribute 3
The output data can be read in acyclically via the Get_Attribute-Single service or written to acyclically via
the Set_ Attribute_Single service.
4 - Data byte for inputs (sensors or initiators)
3 - Data byte for outputs (actuators or valves)
