Manual – MOVITOOLS® - Connection to SIMATIC S7 via MPI

Configuration of drives via MPI

Configuration of SIMATIC S7

3 Configuration of SIMATIC S7

The

FC_MoviTools

function and two data blocks must be added to the STEP7 project

to operate MOVITOOLS

via the SIMATIC S7 MPI. The SEW-EURODRIVE scope of

delivery includes two S7 projects for SIMATIC CPUs with and without DPV1 firmware.

The following sections are a description of configuration and programming.

3.1 Configuration of drives via MPI

Configure the SEW-EURODRIVE drives as usual in the STEP7 hardware configuration.

Note the following instructions for trouble-free operation of MOVITOOLS

via MPI:

• Use the same periphery addresses for the input and output ranges when planning

the parameter channel.

• Assign only PROFIBUS addresses in the range 3 ... 99 to SEW-EURODRIVE drives.

• Use the hardware configurations of SEW-EURODRIVE drives in STEP7 as well as

the device configurations in the GSD file. Make sure you plan the parameter channel

with 4 words and maintain consistency over the entire length when configuring a

drive from SEW-EURODRIVE.

• If you have distributed the SEW-EURODRIVE drives to several PROFIBUS master

systems, these drives may not have identical PROFIBUS addresses. You cannot use

MOVITOOLS

to set the drive parameters in case of identical PROFIBUS address-

es. Make sure that all SEW-EURODRIVE drives on one SIMATIC S7 CPU have dif-

ferent PROFIBUS addresses.

• You should select DPV1 mode (if this mode is supported by the drives and your SI-

MATIC S7 CPU) so that you will be able to use all MOVITOOLS

applications during

operation via MPI.

3.2 Copying data blocks

Operation of MOVITOOLS

requires a communication data block (CDB) as well as a

hardware data block (HDB). Copy these data blocks from the provided SEW-EURO-

DRIVE STEP7 project to your project because both blocks have a version string in the

header.

Communication

data block

The communication data block (CDB) serves as a local data block for the SEW function

FC_MoviTools

. Make sure that there is no access to this data block from your S7 appli-

cation. Manual entries are not necessary for this data block.

Hardware data

block

The hardware data block (HDB) contains the list of SEW-EURODRIVE drive inverters

that can be accessed via MOVITOOLS

and that are connected to the lower-level

PROFIBUS systems. Adjust this hardware data block to match the hardware configura-

tion of your project. The hardware data block is read in via the MOVITOOLS

MPI to

determine the list of connected drive inverters from SEW-EURODRIVE.

The HDB and CDB data blocks are to occur only once in the SIMATIC S7 program.

MOVITOOLS

will not be started via MPI if copies of these blocks with the same version

string in the header are saved with a different data block number in the SIMATIC S7.

You can choose any number between DB1 and DB254 for both data blocks.

MOVITOOLS

does not recognize any data block numbers outside this range.
