9.5.3 Standard function blocks for PROFIBUS-DP and USS
PROFIBUS-DPV1
services
9-114
As you can see in tables /3/ and /4/, a solution for connecting to
MASTERDRIVES via PROFIBUS-DP and USS is available for almost
every SIMATIC S5 and S7 system.
Function block packages DVA_S5 /3/ and Drive ES SIMATIC /4/, which
are available for this purpose, enable convenient access to the process
data and parameters of the MASTERDRIVES from the perspective of
the SIMATIC application programmer.
The control and checkback signals (e.g. in the standard message
assignment specified above) are stored in convenient packages in data
blocks for each drive axis.
The SIMATIC-S7 CPUs with integrated PROFIBUS interfaces (see
table /4/) also support communication with MASTERDRIVES using the
new PROFIBUS-DPV1 services. The DPV1 services allow parameter
transfer to the drive in long messages: all indices of a parameter are
transferred in a single PROFIBUS message frame. This allows, for
example, the transfer of a cam table with 100 interpolation points (=
200 double words) in seconds, in 4 instead of 200 messages.
