Parameter description

2.2.1

DP interrupt mode

41B
This parameter can be used to enable or disable ET 200S DPV1 operation. Data records
and interrupts (can be assigned parameters) are supported by class 1 and class 2 services
after DPV1 mode is enabled.
Requirements:
● The DP master must also support DPV1.
2.2.2

Bus length

42B
≤ 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.
2.2.3 Enable startup for set <> actual configuration
43B
When this parameter is enabled:
● 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.
Exception: Option handling
2.2.4

Option handling in general

44B
