Starting the inverter with PROFIBUS-DP (MC_41A)
Startup
For PROFIBUS DP, data communication between the programmable controller and
drive engineering devices is usually carried out with the setting “Data integrity over entire
length.”
External
diagnostics
For MOVIDRIVE
®
compact
, it is possible to activate automatic generation of external
diagnostic alarms via PROFIBUS-DP during the project planning in the DP master. If this
function has been activated, MOVIDRIVE
®
compact
sends an external diagnostic signal
to the DP master every time a malfunction occurs. You then have to program
corresponding algorithms in the program of the DP master system to evaluate the
diagnostic information. These algorithms can be quite complex.
Recommendation
In principle, it is not necessary to activate the external diagnostic function because
MOVIDRIVE
®
compact
transmits the current drive status in status word 1 during every
PROFIBUS-DP cycle.
Information on
Simatic S7 Master
systems
Diagnostic alarms may also be triggered by the PROFIBUS DP system in the DP master
even if external diagnostic generation is deactivated. As a result, the corresponding
operating blocks (e.g. OB84 for S7-400 or OB82 for S7-300) should always be created
in the controller.
See the Read-me file in the GSD file for additional information.
Ident number
Each DP master and DP slave must have its individual identity number which is
assigned by the PROFIBUS users’ organization. This identity number is used for
uniquely identifying the connected unit. When the PROFIBUS DP master is started up,
it compares the ident numbers of the connected DP slaves with the ident numbers
configured by the user. The user data transfer will only be activated after the DP master
has ensured that the connected station addresses and device types (ident numbers)
correspond to the project planning data. This procedure achieves a high degree of
safety with respect to project planning errors.
The ident number is defined as an unsigned 16-bit number (Unsigned16). The
PROFIBUS users’ organization has defined the following identity numbers for the
