Does Field Point answer correctly to Ping ?

[Franck_Dub]

Our customer has made a 1H-cyclic Ping command from a PC-Win XP to a Field Point standard (1601) via Ethernet, in a way to be informed when the I/O is out of work.
Some times the Ping doesn't get any response, but the Field Point seems to work well. Can you confirm the ability of a Field Point to answer to a classic Ping command.
Thanks a lot for your response.

Hello,
Yes you can as described in the KB linked below:

Hope this helps.

Franck,

To the best of my knowledge, the FieldPoint ethernet modules should always respond to a ping. The cases I personally have seen in which there is no response to a ping is due to the processor being overloaded by the downloaded RT code ([c]FP-20xx series only), incorrect network settings (FP-160x and [c]FP-20xx modules), too much network traffic, corupted firmware, an offline network module and/or duplicated IP addresses.

Also, the ethernet network protocol used by FieldPoint does automatically include keep alive and status information. Depending upon the programming environment you are using, the status should be reported automatically. Thus the Pinging may be redundant.

Regards,
Aaron
