PROFIBUS DPV1
The ET 200iS meet the requirements of DPV1. Naturally, the DP master must also
meet the requirements of DPV1 (refer to the documentation of the DP master).
The following table shows the new functions of PROFIBUS DPV1 slaves compared
with an S7 DP and PROFIBUS DPV0 slave:

Time stamp
* in DPV1, interrupts are also reported with the CPU in the RUN mode. Exception If you operate the ET 200iS with an
S7-400, the interrupts are only reported when the CPU is in the STOP mode.
