■ PING
This function uses the PING command to perform an alive check of external devices whose access is permitted in UDP
communications. Therefore, if external devices do not respond to PING, an alive check error (event code: 00906) occurs.
When this function is used for UDP communications, check if the security setting of external devices (such as a firewall) is set
to respond to PING.
