This section provides a program example of PING tests.

System configuration example

The following system configuration is used to explain the program example of PING test.
System configuration
GX Works3
(1) Programmable controller system
• Power supply module: R61P
• CPU module: R04CPU
• EtherNet/IP network interface module: RJ71EIP91 (start I/O number: 0000H to 001FH, IP address: 192.168.3.51)
(2) EtherNet/IP device (IP address: 192.168.3.50)
Communication content
The PING test is performed by sending an echo request from the RJ71EIP91 to the EtherNet/IP device and checking the
reception of the echo response from the EtherNet/IP device.
PING tests use the buffer memory of the RJ71EIP91 to operate the program.
The following table lists the buffer memory used by the PING test.
