I can not establish a stable ethernet connection from PC to a mitsubishi M70 controllr that uses PLC with Q4A cpu.
this is a new CNC machine and my first experience with Mitsubishi controller [M70 series].
I need to connect to PLC to update the program with new one sent by manufacturer, and I am using Ethernt module for connecting (as instructed by the machine manufacturer).
the situation is:
- I got the icon in taskbar telling me that there is a connection established.
- I have checked IP addresses and other TCP/IP settings as per Mitsubishi manuals.
- sometimes (1 from ten! or twenty!!) I get the message from GX that it has been connected, but very soon and before I can do anything useful, it is disconnected!
- I can not ping the IP address of the CPU successfully but I have the connection icon always there
- I have added GPPW to windows firewall exclusion list, I have tried disabling firewall and anti-virus programs
- I have checked ethernet cable and testing with another one
- GX developer version that I use is 8.43.
now I am looking forward to your advices and I appreciate any helping comment in advance,
best
