Multiprotocol Ethernet Interface User's Manual

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.

13.2.2 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.
