The following terms are used in this manual and the EtherNet/IP setting tool.
Term Description
Originator
The side which opens the connection of the cyclic communication is called
originator, i.e. controllers such as PLC.
Target The side which the connection is opened is called target, such as PLC, I/O devices.
Scan List
Connection setting with targets registered in FP0H. Information required for the
communication with the targets and the device allocation of own unit are registered.
For FP0H, the connection with targets are established according to the scan list.
I/O map
Information required for the transmission from the own unit (FP0H) to other PLCs
and the device allocation of the own unit are registered.
EDS file
(Electric data sheet)
EDS files are provided for each product by each vendor. This file contains the
information on the communication for registering targets in the scan list.
The EDS files of each target should be registered for constructing the scan list with
the setting tool.
Node no.
A node number is set when a target 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 target is
recognized by these numbers, they are used for monitoring the communication
state of each node or controlling the start/stop of the communication.
Connection setting The details of the connections with targets registered in the scan list are set.
Node name Arbitrary node names can be given.
Device name Device names of targets. The device name is registered in the EDS file.
Connection Name
The type of the connection manager registered in the EDS file is selected by the
name. By selecting this, the application type (communication method) is changed.
Application Type
The communication method can be selected by the application type.
Three communication methods are available;
1: Exclusive Owner (Two-way communication)
2: Input Only
3: Listen Only
Although "Exclusive Owner" and "Input Only" are independent connections, "Listen
Only" can be connected only when either of the above connections is established,
and it will be automatically cut if the independent connection is disconnected.
Also, it will be reconnected automatically when the above independent connection
is reconnected.
When FP0H is used as a target, "Input Only" can be selected.
Compatibility Check
Set the operation method of "Compatibility Check" , which checks the information of
the connected target device against the revision of the EDS file.
Three verification methods are available. The default is "Follow Adapter(Target)
Rule".
1: Check
2: Not check
3: Follow Adapter(Target) Rule
