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.

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.
