linkcheck

Description
With this command, you enable the Link Check function on a ring port and you can reset the
function.
Note
Enable Link Check on only one of two connection partners. This can lead to incorrect behavior.
Note
If Link Check is enabled on all devices of a ring at the same time, and several connections
within the ring have problems, this leads to fragmentation of the ring.
1. During commissioning enable the Link Check function for one connection section after the
other by enabling Link Check for the two connection partners connected to a line.
2. To ensure an error-free connection, wait 1 min. before you enable Link Check for the next
connection section.
