[Cause]
1. The name of the robot in TCP/IP is illegal.
2. The name of the connected target equipment in TCP/IP is illegal.
[Countermeasure]
Set the robot name correctly on the Host Communication → TCP/IP screen. Robot names can contain letters (A-Z, a-z), digits (0-9), and minus signs (-).
Blanks, spaces and underscores ( _ ) cannot be used. The first character must be a letter. The last character must be a minus sign. Alternatively, check that the IP address of the corresponding connection target device is correct.
