1.3.2 Backup concept
ADDM supports different hardware configurations for backing up configuration and
system data:
ADDM (client) runs on a mobile network computer, which stores the
backup data on a central server. Via this computer it is possible to transfer
the data between hardware components and server.
ADDM (client or agent) runs on stationary network computer (e.g. operator
panels) and is connected to the automation component. The computer has
also access to the server in the same way as the mobile computer.
The following applies to both solutions:
The ADDM project and the STEP7 project must lie on a common drive for both
solutions!
ADDM Agent in stationary network computers takes the communication with the
automation components. That means an agent can be installed on an operator
panel. All data transfer functions via network are possible without a complete client
installation is necessary on the operator panel.
