11.8.2.3
Reconfigure the hardware when adding a slave
Procedure
1.
Equip the PROFIBUS DP and PROFIBUS PA bus cables with active bus terminals on
both ends, so that the cables are correctly terminated during reconfiguration.
2.
Always make sure not to disconnect any of the bus lines when you add a slave to a
master system.
–
One way to achieve this is to install and wire up additional connectors in the
corresponding expansion slot of the master system. You can then use these bus
connectors to connect a new slave.
–
Another method is to install repeaters or diagnostics repeaters. In this case, add a
slave as follows:
Switch off the repeater function.
Connect the new slave to the free side of the repeater. Note the current installation
guidelines (see
Installation Manual: Installing Automation Systems S7-400, M7-400)
.
Switch on the repeater function again.
11.8.2.4
change process image partition assignment
Procedure
You can change the assignment of a process image partition of an existing module or
compact slave as follows:
1.
Open the properties window of the module or slave. Specify the new process image
partition in the "Addresses" tab.
2.
Download the new configuration with HW Config.
11.8.2.5
reconfigure existing modules in ET200M / ET200iSP stations
Procedure
The procedure for using previously free channels is described under Using a Previously
Unused Channel.
The procedure for reconfiguring already used channels of ET200M / ET200iSP modules is
described under Reconfiguring a Previously Used Channel or under Removing a Previously
Used Channel.
