Device replacement
PROFINET controller supports the device replacement mechanism. When a device
fails, a new, identical device can replace the failed one if plugged in the same
topology location. And this does not need any engineering tool. The new device
is automatically assigned the same parameters and name as the previous one.
The conditions for device replacement to work are:
•
You must replace a previously connected device by an identical device with
an empty station name at the same topology location. For example, the new
device is plugged in the same port as previously in a switch.
•
This feature requires all switches and devices to support Link Layer Discovery
Protocol (LLDP). The easiest way to achieve this is to only use Conformance
Class B devices and switches in the PROFINET network.
