[Cause]
Communication with the specified host took too long and timed out.
[Countermeasure]
Check that the network operates stably and that PING consistently succeeds. Reduce the network communication load if it is high. A hardware fault, such as a broken cable, is also possible. For cable connections, refer to APPENDIX D CABLE CONNECTION (Appendix D, Cable Connection) in R-30iA/R-30iA Mate CONTROLLER Ethernet Function OPERATOR’S MANUAL (R-30iA/R-30iA Mate controller Ethernet function operating manual), B-82974EN/01. Reduce the frequency of calls to standard programs and built-in functions. Insert time intervals if they are called continuously.
