This is a problem I’ve encountered numerous times but have never been able to cure, so I just thought I’d see if any of the Mitsubishi experts here know how to get round this.
After going online and monitoring a program using GX Developer, if I disconnect the PLC from the laptop without first going offline I then can’t modify the program. If I try to make any changes I get a message saying:
“Cannot communicate with the PLC. Execute again after checking the connections with the PLC.”
It seems it still expects to be online and nothing I try gets it back to offline mode. I’ve tried re booting the laptop but this has no effect.
I realise the obvious answer is to make sure I go offline before I disconnect, but I don’t always remember to do this.
Anyone come across this or have any suggestions.
