COGNEX 800-5745-1 Differential expansion module
The .a and .b portion of the port binding is required and is used to define the CCA bandwidth path the network IP interface will be associated with. The path association must be specified and .a and .b are mutually exclusive. The .a designation identifies the network IP interface as being on the Alpha path and the .b designation identifies the network IP interface as being on the Beta path. The paired SAP using the same cc-id as the bound network IP interface must be associated with the opposite path. The leading period must be included as a separator between the ccag-id and the path designator.
The .net-sap portion of the network IP interface
CCAG binding is optional and is used to explicitly define the pairing type as Net-2-SAP. A cross connection between two network IP interfaces is not currently allowed. The .net-sap pairing type is assumed and does not need to be included in the SAP identification. When specified, the leading period must be used as a separator between the path designator and the pairing type. Default .net-sap :cc-id — The :cc-id portion of the port binding is required and specifies the unique cc-id in use by the CCAG network IP interface port binding and the cross connect SAP on the other path.
