Overview of System Configuration Method

4.1 Overview of System Configuration Method
The system configuration is reviewed and selected by the following procedures.
1. Selection of used adapters
Select adapter devices according to applications.
2. Review of system configuration
Review the configurations of the system and network.
Besides the network configuration for the EtherNet/IP communication, review how
Ethernet communications other than the EtehrNet/IP communication is performed.
3. Selection of Ethernet switch HUB
Select a HUB considering the network configuration and the functions of HUB.
The used Ethernet switch HUB should be 100 Mpbs or more.
Some HUBs have the following functions.
Switching HUB:
Multicast filter
function:
QOS function
(Quality of
Service):
Note)
A switching HUB can be activated in a few seconds after the power supply turns ON, however,
a switch with functions such as the multicast filter function or QOS function (Quality of
Service) is called a managed switch, and it takes several tens of seconds to be activated after
the power supply turns ON. Those differences should be considered in the system design.
4-2
Transfers only the data related to devices from the
destination.
Controls the multicast packet transmission to adapters or
scanners.
This is used to suppress the communication load factor
during the multicast communication of PLC link.
Classifies or groups application data, and transfers data
according to the priority of each group.
The cyclic communication data of the EtherNet/IP
communication can be transferred in preference to other
Ethernet communication data.
To make the priority of the cyclic communication of the
EtherNet/IP communication higher, set the port number of
UDP to 2222.
