the device configuration":
1. Remove the terminal block from the master module.
2. Disconnect the master module from the backplane.
3. Insert a new master module on to the backplane.
Procedure if "Download" has been set at one or more ports under "Save the device
configuration":
1. Remove the terminal block from the master module.
2. Disconnect the master module from the backplane.
3. Insert a new master module on to the backplane.
