topological configuration

Device replacement without programming device (PG) and without topological configuration

Device replacement without topological configuration
In addition to both interface modules, the device name is also stored on the BusAdapter
plugged into the interface module. A stored device name in each of the two BusAdapters is a
prerequisite for a device exchange 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
BusAdapter without device name
BusAdapter with device name
Note the following constraints:
• When a BusAdapter is replaced, a device name stored in the BusAdapter is applied to the
interface module after a POWER ON.
• Removal/insertion of the BusAdapter under voltage is not permitted.
Device replacement with topology configuration
IO devices with this function can be replaced in a simple manner:
• The device name does not need to be assigned with the programming device (PG).
The replaced IO device is assigned the device name by the IO controller, not by the
programming device (PG). The IO controller uses the configured topology and the
neighborhood relationships determined by the IO devices for this purpose. All involved
devices must support the LLDP protocol (Link Layer Discovery Protocol). The configured
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 Distributed I/O
system ET 200SP (https://support.industry.siemens.com/cs/ww/en/view/58649293).

Interface module empty
No device name available
The device name from the BusAdapter
is used and copied to the interface
module.
Interface module with device name
The device name from the interface
module is used and copied to the
BusAdapter.
The device name from the BusAdapter
is used and copied to the interface
module if this has a different device
name.
