Download error in AC800M while reassigned Digital Output channel
In control builder M i disconnected a DO channel with defined BoolIO variable and then i defined new global BoolIO variable and connected to same DO channel. when i checked (compile) that DO module found 0 error and 0 warning. then going to online download found an error and download aborted with error.
Then again i inversed the changed i.e old variable conneted to DO channel that time download done successfully.
I don't understand your question. If the boolIO var is defined properly then it shouldn't give any errors. Did you make any changes after adding the variable to the DO channel? Can you send screen shots of your method? Also it depends on where you defined the boolIO variable. You have to keep it in a connected application to that controller.
