Adding an
allocation
SIPROTEC PROFIBUS-DP - Communication profile
C53000-L1840-B001-03
To add or remove an information to "Source system interface" or "Destination system
interface" set/reset the cross ('X') in the associated column of the DIGSI Configu-
ration matrix (pop-up menu when pressing the right mouse button).
Note:
• The max. number of routable objects of an information type varies according to the
chosen mapping file.
If e.g. a measured value not routed in the mapping file per default shall be trans-
ferred via PROFIBUS-DP, then first a measured value already routed has to be
removed from system interface so that the position gets available in the PROFI-
BUS-DP message.
• An error message is shown if all routing possibilities of an information type are
occupied and if it is nevertheless tried to route an information of this type.
Adding an allocation requires (in addition to the identification in the system interface
column of the DIGSI Configuration matrix) the selection of the position of the
information in the PROFIBUS-DP message as well as the definition of scaling values
for measured values (scaling of measured values ref. to chap. 4.3).
Therefore after adding the allocation, the Object properties dialog window which
is used to define the message position of the information is opened automatically
(property sheet Protocol info source or Protocol info destination).
