This subsection describes how to check the state of communication
between the CNC and personal computer.
Checking the connection status and settings
If communication with the CNC is not satisfactory or fails from time to
time, check the communication link by using the method described
below. The ping command is used to check communication.
See Item 6 of Section 3.2, ”EMBEDDED ETHERNET MAINTENANCE
SCREEN”.
If no response is received from the remote device, the cause is considered
to be a hardware connection error and/or software setting error. Check the
hardware connection and software settings.
An example where a personal computer (OS: Windows NT 4.0) is used
is described below.
Method of checking:
Open the command prompt, then enter ”ping NC–IP–address”. A normal
connection has been established if a response is received.
The example below supposes that the IP address of the CNC is
192.168.1.1.
