Getting error code 33,028 when trying to connect to Siemens S7 Driver. I'm using VTSCADA Light Version 12.0.04.
Any Help is Appreciated
Open the PLC project in the S7 TIA Portal software.
Go to Project View
In the Project Tree window, select the device that is causing the error.
Hit Alt-Enter to bring up the Properties dialog.
On the General tab, select Protection.
Ensure that one of the following options is checked:

Check ‘Permit access with Put/Get communication from remote partner.‘
Click the OK button to save the settings.
Compile and save project, then download modified program to controller.
