Precautions for programming
● Insert the UNITSEL instruction immediately before this instruction and specify the unit (built-
in ET-LAN in the CPU unit) and the connection number.
● If the partner unit IP address is not set, an error occurs.
● Use the ETSTAT instruction to check the target IP address for the PING request.
■
Operand [S] setting
The instruction requests the sending of PING for the number of times that is specified for [S].

Execution result code [D]
● In the case of abnormal request (10 to 13), it is set when the instruction is executed and the
PING request is not performed.
● The response error (20) occurs when no response is returned from the Ethernet task.

error
U0 to U1000 (ms)
Response time is in 10 ms unit. When it is less than 10 ms, 0 is stored.
PING request instruction is being executed.
The number of requests to send is not in the available range (1 to
10).
The specified connection is set to "Not use".
Ethernet is disconnected.
Ethernet is being initialized.
It occurs when no response is returned from the Ethernet task.
