6.1.3 Periodic Communication (Implicit) System
Implicit Message provided in periodic communication in XGB EtherNet/IP I/F module means a suggestive and implied
message. As this message contains header information to the minimum except for the data in frame, it also refers to
the message which is impossible to see what data means. In addition, if we translate it in different way, this message
means that header information is small in quantity, so the process of translating the frame has been simplified and it is
possible to process data quickly. In EtherNet/IP, connection between client and server is set up with the parameter for
sending this data.
Client requires connection and it becomes the object that receives and consumes data, and sever comes to transmit
the said data in transmission period (Requested Packet Interval: RPI) and communication method (Unicast/Multicast)
like the way client wants Thus, client comes to set up consumed tag and server will set up produced tag (XGT
EtherNet/IP IF: Input Only Type).

Notice
Implicit Server is created also in Implicit Client. Server can set up timeout in the period that client grants according to types.
Using data that client provides, it is possible to output to his own module .
