2.2 Cyclic Communication Function
2-3
2.2 Cyclic Communication Function
The cyclic communication is a function for connecting from a scanner device to an adapter
device and sending data mutually in a specified cycle after completing the connection.
The scanner device is a controller such as PLC.
The adapter device is a device such as a robot controller, encoder or IO device.
Scan list is a list that defines the connections between the scanner device and multiple
adapter devices.
A constant cycle is called RPI (Requested Packet Interval).
The side which opens the connection of the cyclic communication is called originator, and the
side which the connection is opened is called target.
The scanner device can be used as the adapter device.

Description of EtherNet/IP Communication Function
2-4
2.3 Definitions of Terms
The following terms are used in this manual and the EtherNet/IP setting tool.
Term Description
Scan list
The scan list is the connection settings with adapter devices registered for a
scanner 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 adapter
devices 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 scan
list with the setting tool.
Originator and Target
The side which connects the connection of the cyclic communicationo is called
originator.
The side which the connection of the cyclic communicationo is connected is called
target.
Node number
Node 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 adapter
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 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 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.
The following communication methods are available;
1 : Exclusive Owner (Two-way communication)
2 : Input Only
3 : Listen Only
For a normal adapter device, select 1 (Two-way communication).
Although "Exclusive Owner" and "Input Only" are independent connections, "Listen
Only" 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 is
reconnected.
Although the FP7 can be used as an adapter, it can be connected only when "Input
Only" is selected.

2.3 Definitions of Terms

Term Description
Compatibility check
A method for verifying the revision of a used EDS file and the information that the
device actually used has is selected.
Three verification methods are available. The default is "Follow Adapter Rule".
1 : Check
2 : Not Check
3 : Follow Adapter Rule
Communication method
Either instance communication (number specifications) or tag communication (symbol
name specification) is displayed.
For connecting from a scanner to adapters, there are methods which establish the
connection by specifying numbers or by specifying symbols.
Even when connecting by specifying symbols, numbers are assigned to packets
during the actual cyclic communication.
When selecting a connection, the methods available for the connection are displayed.
When using the FP7 as an adapter, the both methods can be used, however, in the
case of instance method, the selectable instance numbers are 100 to 199.
Send trigger
The transmission timing is selected from Cyclic or COS (Change of state).
However, COS depends on devices.
COS is basically a cyclic communication, however, it also performs transmission when
sent data changes.
The FP7 does not support COS.
COS transmission
disable time
Although COS performs transmission when sent data changes, transmission is not
performed even if the unit detects the data change within this time.
Timeout period
In the cyclic communication, the timeout is judged on a receiver side to send
transmission data as UDP packet.
The timeout period is selected from 4, 8, 16, 32, 64, 128, 256 and 512 times of RPI.
The timeout period should be 10 msec or more.
RPI can be specified for T>O direction and O>T direction separately, so each timeout
period may be different values.
Input setting (T>O) This is the setting for the transmission from a target to the FP7 (originator).
RPI
(Requested Packet
Interval)
Set the transmission interval for the cyclic communication.Set a value within the
communication capacity of the adapter.
The usable RPI range depends on devices.
For the FP7, it is 0.5 ms to 10 s (by 0.5 ms).

Description of EtherNet/IP Communication Function

Term Description
Connection type
Select a communication method that is selectable for the selected connection.
1 : 1:1 communicaion (Point to Point)
2 : Multicast communication (Multicast)
The point-to-point communication is a 1 to 1 communication between the connection
source and destination.
Transmission packet is received by the source device or destination device only.
Other devices connected to the same HUB does not receive the transmission packet.
In the mutlicast communication, transmission data is sent as multicast packet.
By connecting multiple sources to the same connection, single multicast packet can
be received by the multiple connection sources.
The multicast packet is basically received by all the devices connected to the same
HUB which includes the devices unrelated to the communication, and it leads to an
unnecessary communication load.
Therefore, set not to exceed 100% with the load factor caclulation of the setting tool
when using the mutlicast communication.
Also, it is recommended to use a HUB with a multicast filter.
Instance ID/Tag name Set an instance ID or tag name according to the communication method of the
selected connection.
Data size
Set the communication data size according to the communication setting of each
adapter device.
Set this as well as changing the setting for the scanner, otherwise the communication
cannot be performed as it does not match the setting of adapters.
Refresh method
There are the following two refresh operations.
1 : Transfers the data sent to adapters to send buffers from allocated operation
memories.
2 : Transfers the data sent from adapters to allocated operation memories from
receive buffers.
The refresh method can be selected from three types, Batch, Divice and Instruction.
Parameter change Parameters that can be changed by EDS can be changed.
PPS performance index
(Packet per sec) This is an index of sent/received packets processed in one second.
Normal packet and
large packet
The packet whose size is within 504 bytes is called normal packet. The packet whose
size is 505 bytes to 1444 bytes is called larget packet.
The amximum communication performance varies according to the data size used for
communication.
Performance index of FP7
When the size is 504 bytes or less: Max. 10000 pps
When the size is 505 bytes or more: Max. 5000 pps

2.3 Definitions of Terms
2-7
Term Description
Protocol used for cyclic
communication
The cyclic commuication is performed using UDP.
The used port number is 2222.
Heartbeat
In the case of InputOnly or ListenOnly, data is sent from the target, however, a packet
called heartbeat whose size is 0 is also sent from the originator (FP7).
For the RPI of this heartbeat, the value 16 times of the target is used automatically.
Heartbeat is used for confirming the continuation of connection on the target side.
It is used for detect the timeout.
Forward open This is a command for opening the connection of EtherNet/IP and sent using TCP.
The used port number is 44818.
Large forward open This is a command for opening the connection when sending/receiving data whose
size is larger than 504 bytes.
RUN/IDLE bit
This bit indicates the operation state (RUN/IDLE) of a device that is sent from a
scanner or adapter duuring the cyclic communication.
RUN : 1
IDLE : 0
When the RUN/IDLE bit does not become a RUN state, the adapter device may not
operate properly.
For details, refer to “8.1.2 Cyclic Communication State Tables of EtherNet/IP”.
【
Note
】
- Do not use "2222" and "44818" for the port numbers set to the connections of Ethernet
communication.
