6.1.4 PROFIBUS DPV1 operation
The ET 200M fulfils the requirements in accordance with DPV1. If you wish to use the DPV1
functions, then the DP master must of course fulfill the requirements in accordance with
DPV1 (refer to the DP master documentation).
Functions of the PROFIBUS DPV1 slave
The following table shows you the new functions of the PROFIBUS DPV1 slave compared
with a PROFIBUS DPV0 slave:
Table 6- 2
Function
Parameter assignment and configuration with GSD file
Cyclic data exchange
Acyclic data traffic
(read / write data record):
•
•
Diagnosis
•
•
•
Interrupts

•
Other functions

The assignment of the functions to the versions of the interface module can be found in the
1
"Compatibilities between the IM 153-x (Page 241)" appendix.
If configuring with HW-Config, with some functions S7-specific features are set.
2
One interrupt can be used per diagnostic frame. With DPV1 (and S7 DP) there is an interrupt that
3
comprise a slave diagnosis that is accompanied by an acknowledgement mechanism that does not
exist with DPV0.
Up to IM 153-2Bx00 the time stamping is available only in the S7 system environment.
4
without GSD-file or with GSD rev. 2
5
with GSD rev. 2
6
as of GSD rev. 3
7
only if the GSD-file is imported and if, in HW-Config the DPV1-mode is selected
8
With S7 DP the interrupts are not reported if the CPU is in STOP.
9
as of GSD rev. 4
10
as of GSD rev. 5
