Bus length
≤ 1 m: The default setting for the maximum bus length is 1 m.
> 1 m: The bus length of the ET 200S is > 1 m and can be up to 2 m. However, this setting
will increase the response time of the ET 200S.

●
Removing and inserting modules during operation will not lead to an ET 200S station
failure.
●
If the actual configuration differs from the expected configuration, data exchange between
the ET 200S and the DP master will continue.
When this parameter is disabled:
●
Removing and inserting modules during operation will lead to an ET 200S station failure.
●
If the actual configuration differs from the expected configuration, data exchange between
the ET 200S and the DP master will cease.
