Description of EtherNet/IP Communication Function2-42.3 Definitions of TermsThe following terms are used in this manual and the EtherNet/IP setting tool.Term DescriptionScan listThe scan list is the connection settings with adapter devices registered for ascanner device.The scanner device is connected with adapter devices according to the scan list.EDS file(Electric data sheet)An EDS file contains the information on the communication for registering adapterdevices in the scan list.EDS files are provided for each product by each vendor.The EDS files of each adapter device should be registered for constructing the scanlist with the setting tool.Originator and TargetThe side which connects the connection of the cyclic communicationo is calledoriginator.The side which the connection of the cyclic communicationo is connected is calledtarget.Node numberNode numbers can be set when an adapter device is registered in the scan list.Numbers that do not overlap are allocated in the scan list as node numbers.Node numbers are not used in the cyclic communication, however, as each adapteris recognized by these numbers, they are used for monitoring the communicationstate of each node or controlling the start/stop of the communication.Connection setting The details of the connections of adapters registered in the scan list are set.Node Name Arbitrary node names can be given.Device name This is the device name of an adapter.The device name is registered in the EDS file.Connection nameThe type of the connection manager registered in the EDS file is selected by thename.By selecting this, the application type (communication method) is changed.Application typeThe communication method can be selected by the application type.The following communication methods are available;1 : Exclusive Owner (Two-way communication)2 : Input Only3 : Listen OnlyFor a normal adapter device, select 1 (Two-way communication).Although "Exclusive Owner" and "Input Only" are independent connections, "ListenOnly" can be connected only when either of the above connection is established,and it will be automatically cut if the above independent connection is disconnected.Also, it will be reconnected automatically when the above independent connection isreconnected.Although the FP7 can be used as an adapter, it can be connected only when "InputOnly" is selected.
