2.2.1
Device replacement
Device replacement
Device replacement without topological configuration
The device name is also stored on the BusAdapter in addition to the interface module. A
device name saved on the BusAdapter is the requirement for device replacement without
topological configuration.
Replacing the interface module produces a range of scenarios for using the device name.
Table 2- 2
Scenarios for using the device name
Interface module empty
Interface module with device name
BusAdapter without device name
No device name available
The device name from the interface
module is used and copied to the
BusAdapter.
BusAdapter with device name
The device name from the BusAdapter
is used and copied to the interface
module.
The device name from the BusAdapter
is used and copied to the interface
module if this has a different device
name.
Be aware of the following constraints:
●
Resetting to factory settings deletes the device name in both the interface module and the
BusAdapter. To prevent the device name from being deleted in the BusAdapter, you can
remove the BusAdapter from the interface module before resetting to factory settings.
●
When a BusAdapter is replaced, a device name stored in the BusAdapter is applied to the
interface module after a POWER ON.
●
Do not pull/plug the BusAdapter while under voltage.
Device replacement with topological configuration
IO devices with this function can be replaced in a simple manner:
●
The device name does not have to be assigned with the programming device.
The replacement IO device is assigned the device name by the IO controller and not by the
programming device. The IO controller uses the configured topology and the neighboring
relationships determined by the IO devices for this purpose. All involved devices must
support the LLDP protocol (Link Layer Discovery Protocol). The configured target topology
must match the actual topology.
If the IO devices were already used in another configuration, reset them to factory settings
before reusing them. You can find information on this in the system manual ET 200SP
