Class1 Communications Communication Example

This section describes examples of executing Class1 instance communications and Class1 tag communications between the
CC-Link IE TSN Plus module and an EtherNet/IP device.
Data communications between the send/receive data assigned to the buffer memory area and the CPU
device can be used the following methods: using by the MOV instruction or the FROM/TO instruction and
using with a module FB.
For details on the communication method with a module FB, refer to the following.

System configuration

The following system configuration is used to explain communication examples of Class1 instance communications and
Class1 tag communications.
(1)
(1) Programmable controller system (originator)
• Power supply module: R61P
• CPU module: R04CPU
• CC-Link IE TSN Plus module: RJ71GN11-EIP (start I/O number: 0000H to 001FH, IP address: 192.168.4.51)
(2) Programmable controller system (target 1)
• Power supply module: R61P
• CPU module: R04CPU
• CC-Link IE TSN Plus module: RJ71GN11-EIP (start I/O number: 0000H to 001FH, IP address: 192.168.4.1)
(3) Programmable controller system (target 2)
• Power supply module: R61P
• CPU module: R04CPU
• CC-Link IE TSN Plus module: RJ71GN11-EIP (start I/O number: 0000H to 001FH, IP address: 192.168.4.2)
