REXROTH efc series - Acyclic Communication

6.3 Acyclic Communication
6.3.1 Message Parameters
To allow parameter for being set via Ethernet/IP interface, all function code pa-
rameters can be accessed, via a manufacturer-specific class object, with corre-
sponding instances for each function code parameter. The function code param-
eters can be either addressed via an "Unconnected Explicit Message" (UCM) or
via a "Connected Explicit Message" (Class 3).
In EtherNet/IP communication, the objects are addressed according to the fol-
lowing scheme: CLASS → INSTANCE → ATTRIBUTE.
Class: All parameters of the EFCx610 frequency converter are mapped to the
manufacturer-specific classes 100 (0x64) + Subdevice index, i.e.: Subdevice 0 -->
Class 100, Subdevice 1 --> Class 101 … Subdevice 98 --> Class 198.
Instance: The instance number is identical to the numeric coding of the EFCx610
parameters.
Attribute: The attribute number is identical to the element number during access
via function code parameters.
Message configuration below shows an example of parameter E0.26.

Refer to chapter 8 for the numeric coding of EFCx610 parameters.
