Communication with the S7-300
5.2 DPV1 (X1 only as PROFIBUS DP interface)
Note
If you deselect "Startup with different target / actual configurations" in the Technology CPU
properties in STEP 7, then the Technology CPU will boot even if the stations configured on
DP-DRIVE are missing.
Connectable devices
You can connect drives to PROFIBUS DP(DRIVE), e.g.:
• MICROMASTER 420/430/440 and COMBIMASTER 411
• SIMODRIVE 611 universal
• SIMODRIVE POSMO CD/SI/CA
• MASTERDRIVES MC/VC
• ET 200M with IM 153-2 (isochronous!) and SM 322 for additional cam output
• ET 200S with IM 151-1 high feature
• SINAMICS S120 (optional with TM15 or TM17 high feature for high-speed cams)
• ADI4 (analog drive interface)
• Isochronous PROFIBUS encoder "SIMODRIVE sensor isochronous"
The components configured in HW Config are displayed in the "Hardware Catalog" window
in HW Config. To show the screen, select profile "SIMATIC Technology CPU" in HW Config.
To ensure that the profile's selection list is complete, you must have installed the most recent
version of S7-Technology.
Non-connectable devices
We would not recommend operating active PROFIBUS stations (PGs, PCs, OPs, TDs, etc.)
on PROFIBUS DP(DRIVE). The DP cycle will be burdened by additional access times if you
do operate these PROFIBUS stations on DP(DRIVE). In this case, isochronous processing
of drive information cannot be guaranteed.

Acyclical access with DPV1
New automation and process engineering tasks require the range of functions performed by
the existing DP protocol to be extended. In addition to cyclical communication functions,
acyclical access to non-S7 field devices is another important requirement of our customers,
and was implemented in the standard EN 50170. In the past, acyclical access was only
possible with S7 slaves.
