Overview

Use the Control Expert ping function to send an ICMP echo request to a target Ethernet device to determine:

  • if the target device is present, and if so

  • the elapsed time to receive an echo response from the target device

The target device is identified by its IP address setting. Enter only valid IP addresses in the IP Address field.
