SENTRON supports PROFIBUS DPV1 (1)

PROFIBUS DPV1 is extension of existing PROFIBUS functions, compliant to older devices

Very easy communication functions to devices supporting PRODIBUS-DPV1 with a configuration software (Switch ES Power) or SCADA system (WinCC)

Devices supporting DPV1 can talk to two PROFIBUS masters at the same time

Communication without DPV1:

• Data to be transmitted with every cyclic telegram

• Amount of data can not be changed in the operating mode

• Low performance if amount of data is too big

SENTRON supports PROFIBUS DPV1 (2)

Communication with DPV1:

• Communication of datasets DS with the maximum size of 245 Bytes in just one additional telegram

• DPV1 telegrams will only be transferred once triggered by a customers software, for example Switch ES Power

• The cyclic transmission is running parallel
