Instance Attributes (Instance #1)
# | Name | Access | Data Type | Description |
|---|---|---|---|---|
1 | Port Type | Set | UINT16 | Enumerates the port (See CIP specification, available from www.odva.org) |
2 | Port Number | Set | UINT16 | CIP port number associated with this port |
3 | Link Path | Set | Array of UINT8 | Logical path segments which identify the object for this port. |
4 | Port Name | Set | Array of CHAR | String (max. no. of characters is 64) which names the port. |
5 | - | - | - | (reserved) |
6 | - | - | - | (reserved) |
7 | Node Address | Set | Array of UINT8 | Node number of this device on port. The data type restricts the range to a Port Segment. The encoded port number must match the value specified in attribute #2. A device which does not have a node number on the port can specify a zero length node address within the Port Segment (i.e. 10h 00h). In case the node address changes during runtime, the host application is responsible for updating this attribute as well. |
8 | Port Node Range | Set | Struct of: UINT16 (Min) UINT16 (Max) | Minimum and maximum node number on port. Support for this attribute is conditional; the attribute shall be supported provided that the node number can be reported within the range of the data type (e.g. DeviceNet). If not (as is the case with networks such as EtherNet/IP which uses a 4 byte IP address), the attribute shall not be supported. |
