2023-12-08
When you are ready to communicate through AJ71QE71, execute ping program in MS-DOS mode to check whether the connection is correct before the GPPW of Mitsubishi PLC starts communication. Support communication with the VION touch screen through the serial port.
The following indicates that communication is possible
C:\ping 192. 168. 0. two
Reply from 192. 168. 0. 2:bytes = 32 time<10ms TTL=32
The following indicates that communication is not allowed
C:\>ping 192. 168. 0. two
Request timed out.
If the ping fails, check the connection between the cable and the module, the IP address, and the settings in other WINOOWs.
