2.2 Parameter description
2.2.1 DP interrupt mode
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 operation is enabled.
Requirements:
● The DP master must also support DPV1.
2.2.2 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 a maximum 2 m. This setting will
increase the response time of the ET 200S.
2.2.3 Enable startup for set <> actual configuration
When this parameter is enabled, and
● Modules removed and inserted during operation will not lead to a ET 200S station failure.
● The actual configuration differs from the expected configuration, the ET 200S remains
engaged in data transfer with the DP master.
When this parameter is disabled, and
● Modules removed and inserted during operation will lead to an ET 200S station failure.
● The actual configuration differs from the expected configuration, there is no data transfer
between the DP master and the ET 200S.
Exception: option handling with RESERVE modules.
2.2.4 Option handling in general
These parameters can be used enable or disable the option handling for the entire ET 200S.
