- 140 -
Incorrect setting (2)
When the IP addresses set up for the PC and NC are correct, and the NC
power is on, if any other kind of setting is incorrect, the dialog box may
appear as shown below.
If the “Get System Information test...” line does not appear, the
probable causes are:
(1) An IP address for the PC or the devices for which a TCP/IP has
been set up, rather than for the NC, has been specified.
(2) The “TCP port number” set for the NC is incorrect.
If the message “No option (Extended driver and libraries function)” is
displayed, the NC lacks the “extended driver library option.” The
embedded Ethernet protocol does not need this option, though.
