6SE7087-6QX70 (Version AK) Siemens AG
8.2-2 Compendium Motion Control SIMOVERT MASTERDRIVES
♦ Useful data is exchanged with the master according to the
"PROFIBUS profile for variable-speed drives", PROFIdrive.
♦ Acyclical communications channel for transferring parameter values
up to a length of 101 words with a SIMATIC S7-CPU.
♦ Acyclical communications channel for linking the PC-based
Drive ES start-up and service tool.
♦ Automatic adoption of the useful data structure defined in the master.
♦ Monitoring of the bus interface.
♦ Supporting of SYNC-type PROFIBUS control commands for
synchronized data transfer from the master to several slaves.
♦ Supporting of FREEZE-type PROFIBUS control commands for
synchronized data transfer from several slaves to the master.
♦ Extremely simple parameterization of the CBP via the PMU of the
basic unit.
♦ Flexible configuration of the setpoints/actual values up to a maximum
of 16 process data words
♦ Clock synchronization at the isochronous PROFIBUS for
synchronization of processing by the master and slaves
(MASTERDRIVES MC only)
♦ Cross traffic for direct data exchange between slaves
♦ Direct access to a drive by a SIMATIC OP
♦ USS protocol
♦ Acyclical parameter channel in accordance with PROFIdrive profile,
version 3, with data block 47
♦ Standard telegrams 1 to 6
For MASTERDRIVES MC and during use of T100, T300 or T400, please
pay attention to the note in Section 2.3.2 "TB Blocks".
