I need to backup some %MWi varibales in an M340 program without stopping the PLC. Any ideas?
Also what is the Save Variable attribute used for? Can it do the job?
Thanks for help...
 
in the "plc" menu there is a transfer data option. transer from plc to pc. you can do this without stopping the plc. You must specify the range of variable it must transfer
