There are several situations in which PLC and computer communication are not available. 
(1)PC serial port is broken, there is no way to use it.
(2)USB to 232 for laptop, the driver is not installed.
(3)PC serial port may leak, burn the PLC download protection resistor.
(4)Select wrong COM port on PC hardware.
(5)Can communicate, communication is unstable, check the line, try to replace the computer.
Summary: There are a variety of situations in which PLC can't download. It is recommended to use the replacement method to troubleshoot, such as replacing the computer, changing the download cable, replacing the PLC, etc.

2.PLC internal data (program) error 
Fault performance: data jumps, the program does not follow the normal execution. Possible causes:
(1)Use GX 8.52 or GX8.86 or Works 2 programming software not provided by our company, After replacing the software, turn off
