Some of the changes you can make will be visible immediately, on connected clients.
Other changes require some other event to occur, before the change takes effect.
For example, if you change the Security Code assigned to an HMI tag, the new security
check will not occur until there is an attempt to write to the tag. When that happens, the
tag write will be validated against the new Security Code.
