Brief:

• Function and Procedure calls return proper error code on client side if user access denied;
• readOnly flag for properties on client side if there is no write permission;
• set a method property as invisible on client side if there is no execute permission;
• BeginUpdate and EndUpdate methods return proper error code on client side;
• object attributes locking on client side if there is no write access;
• getAvailableFunctionBlockTypes method returns an empty list on client side if there is no write permission (only for a device);
• setOperationMode and setOperationModeRecursive methods return proper error code on client side;
• acceptsSignal method returns false on client side if there is no write permission;
• tests;
