Communication Test

This function checks if transient transmission can be performed from the own station to the communication target.
Depending on selection for "Communication Method" ("Network No./Station No." or "IP Address"), the range that can be
checked may vary.
Selection of "Communication Method"
Network No./Station No.
IP Address
Explain the procedure of the communication test.
Since this function uses ping, an error, "a communication test target station communication error" (error code D919H) occurs
if the communication target does not respond to ping. When executing this function, check if the security setting (such as
firewall) of the communication target is set to respond to ping. Moreover, if the target is set not to respond to ping in the
security settings (such as a firewall), it may take some time until a timeout error occurs on the engineering tool. For details on
when communication of the engineering tool is not allowed in the firewall settings of Windows, refer to the following.
