Communication Test - Mitsubishi Electric MELSEC iQ-F FX5 Series User Manual

Communication test

This function checks if transient transmission data can be properly routed 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.

The following explains the procedure for a communication test.
Precautions
• When a relay sending station is set to "Target Station", the communication test ends with an error. Set a relay receiving
station to "Target Station".

station
• When "Network No./Station No." is selected for "Communication Method" and a station mounted on the same system
(module connected with a connector or cable) is set for "Target Station", the communication test ends with an error.
• This test cannot check whether transient transmission can be performed from the connected station (own station) to a
station on another network by specifying an IP address.
• Since this function uses PING, the 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.
