Distributed I/O Device ET 200M
EWA-4NEB780600602-06
6.1.4 PROFIBUS-DPV1 Mode
The ET 200M fulfills the requirements of DPV1. If you want to use the DPV1
functions, the DP master must of course also fulfill the requirements of DPV1 (see
the documentation for the DP master).
The table below shows you the new functions of the PROFIBUS-DPV1
slave compared to a PROFIBUS-DPV0 slave:

1 The assignment of the functions to the interface module versions is given in Sections 9.1 and 9.2.
2 If parameterization is performed using HW Config, S7-specific features are set for some functions.
3 One interrupt can be used per diagnostic frame. With DPV1 (and S7-DP) an interrupt consists of a slave
diagnosis which is accompanied by an acknowledgment mechanism which does not exist in DPV0.
4 Without device master file or with device master file revision 2
5 With device master file revision 2
6 As of device master file revision 3
7 Only if the device master file has been imported and if the DPV1 mode is selected in HW-Config.
8 With S7-DP the interrupts are not reported when the CPU is in the STOP mode.
9 As of device master file revision 4
10 Time stamping is currently only available in the S7 system environment.
