Please Help. V570 can't connect


Recommended Posts

Hello Nick,

 

Is the battery backup installed in the V570? If the unit is powered down and the battery is low, or not installed than it is possible to lose the program and display no application. You will need to re-download the program.

 

We recommend performing the Download All and Burn download option. This will download the program into the flash memory of the controller which will retain the program in case the battery backup fails when power is cycled.

Hi, 

 

Usually when the PLC is in stop mode the default baud rate is 115200.

Try to set in VisiLogic communication & OS menu the baud rate to 115200 and then try to download application.

if you are still unable to connect - let me know what error message do you get?
