ICC
•
Supports unconnected messages (UCMM), and up to 16 simultaneous
class 1 (I/O) or class 3 (explicit) connections.
•
Assembly instances 100 and 150: if a register entry in the consumed data
configuration array is 0, then any consumed data that corresponds to that
location will be ignored. Conversely, if a register entry in the produced
data configuration array is 0, then any produced data that corresponds to
that location will be a default value of 0. Refer to section 10.8.4 for further
information on the data configuration arrays.
•
Point-to-point class 1 connected messages will be produced targeting the
IP address of the device that instantiated the connection, port 0x08AE (port
2222).
•
If a class 1 connection’s consuming half (O
→
T) times out, then the
producing half (T
→
O) will also time-out and will stop producing.
•
If a class 1 or class 3 connection timeout occurs, the driver will trigger a
timeout event as described in section 10.7.4.

ODVA AC/DC Drive Profile
The interface card supports the ODVA AC/DC drive profile. No special
Ethernet/IP configuration of the interface card is required when using the
AC/DC drive profile: all that is needed is that the controller must target either
assembly instances 20 & 70 or 21 & 71 in its connection parameters.
The AC/DC drive profile
implementation provides
support for several
required CIP objects,
which are specified in
Table 3. While the
various supported
attributes of all of these
objects are accessible via
explicit messaging, the
main intent of using the AC/DC drive profile is to interact with the predefined
input and output assembly instances via an I/O connection. The structure of
these assembly instances is defined by the Ethernet/IP specification in order to
engender interoperability among different vendor’s products. This section will
focus primarily on the format of the AC/DC drive profile I/O assemblies
supported by the interface card, and the inverter data which their various
constituent elements map to.
