behaviour is that the reference speed of the drive is set to the
requested value.
This is an example of
Explicit Messaging
where each attribute of a
class is set individually. While this is allowed, it is inefficient.
Instead
Implicit Messaging
using Input and Output Assembly
Instances is recommended.
Implicit Messaging
allows the
Ethernet/IP Master to set or get predefined groups of attributes in
a single message exchange. Assembly Instances supported by
the RETA-01 are listed and defined in chapter
,

ODVA output attributes
This section briefly describes the instances found in the ODVA
AC/DC Drive Profiles output assemblies. Not all attributes listed
here will be supported by all output assembly instances.
Run Forward & Run Reverse (Control Supervisor Object)
These attributes are used to assert run and stop commands to
Control Supervisor Object state machine according to the
following table.
Table 9. Run/Stop event matrix
