Program Example of PING Test

This section provides a program example of PING tests.

System configuration

The following system configuration is used to explain the program example of PING test.
(1)
(1) Programmable controller system
• Power supply module: R61P
• CPU module: R04CPU
• CC-Link IE TSN Plus module: RJ71GN11-EIP (start I/O number: 0000H to 001FH, IP address: 192.1.0.5)
(2) EtherNet/IP device (IP address: 192.1.0.2)

Communication description

The PING test is performed by transmitting an echo request from the CC-Link IE TSN Plus module to the EtherNet/IP device
and checking the reception of the echo response from the EtherNet/IP device.
For the PING test, the buffer memory of the CC-Link IE TSN Plus module is used to operate the program.
The following table lists the buffer memory used by the PING test.
