官方故障排除步骤
Cause: A Hosttable entry is configured with an illegal name. If n1 = 1, the illegal name is in the local host table. If n1 = 2, the illegal name is in the shared host table. n2 indicates the entry number of the name in the respective table. Remedy: Change the robot Hosttable entry in the Host Comm TCP/IP screen to a legal name. A legal Hostname is a text string of characters drawn from the alphabet (A-Z, a-z), digits (0-9), and minus sign (-). No blank or space characters are permitted as part of a name, nor is the underscore character (_). The first character must be an alpha character. The last character must not be a minus sign.
