Swapping devices

Hirschmann devices support the device swapping function with an
engineering station.
If identical devices are being swapped, the engineering station assigns the
parameters of the original device to the new device.
The device swapping function with Simatic S7 requires the following
prerequisites:

S7 300 with SW release from V2.7 (currently available for CPU 319) or
S7 400 with SW release from V5.2
 Hirschmann device SW release from 05.0.00

Neighboring device(s) support(s) LLDP
 Topology (=neighborhood relationships) is configured and loaded onto
SPS
Device swapping requires the following conditions:

the replacement device is of exactly the same type as the device to be
replaced.
 the replacement device is connected to exactly the same place in the
network (same ports and neighboring devices).
 the replacement device has a Profinet default configuration. Set the
device name to "" (null string).
If all these conditions are fulfilled, the engineering station automatically
assigns the parameters of the original device (device name, IP parameters
and configuration data) to the replacement device.
Procedure for swapping devices:
 Reset the replacement device to the state on delivery:
- System name "" (= null string)
- IP address = 0.0.0.0 or DHCP
- PROFINET IO activated
 Make a note of the port assignment of the original device and remove the
original device from the system.
The PLC now detects an error.
 Now insert the replacement device at the same position in the network.
Make sure the port assignments are the same as for the original device.
The PLC finds the replacement device and configures it like the original
device.
The PLC detects normal operation again.
If necessary, reset the PLC to "Run".
