8. Data Mapping

Two possibilities exist for data mapping, the default data map as described below and a user
defined data map which can be created by the MNavigate Mapping Tool for project specific
tailoring of the communication data.
The default data map is a selection of data based on typical requirements. If this selection is
not accepted in the project, a user data map has to be created.

8.1 User Data Map

All available data in a UMC can be assigned to the corresponding register addresses by using
the MNavigate Mapping Tool. This is a proprietary tool for ABB to program the PROFIBUS
registers according to customer requirements.
If there is a communication interruption between a UMC (e.g. device removed)
and the related Digital Gateway, then the information configured in the mapping
for this device will show the last values before the interruption.
At the same time the Life Bit for this device, which shall be always part of a User
Mapping, is cleared to 0 (1 is indicating device is communicating).
This Life Bit information for each configured device shall be used in DCS to
validate the Read-Data from the device. An Alarm shall be raised if Life Bit value
becomes "0" to indicate that the communication to that single device is disturbed
and no remote control of the connected motor/load is possible any longer.
For
For INSUM 2 Upgrade solution with Profibus DP interface, a default Profibus
mapping is available for the interface between Digital Gateway and DCS. This map-
ping follows the INSUM 2 Profibus Gateway default mapping.

8.2 Default Data Map

Through the default PROFIBUS data map 60 UMC data are provided. Process operation data
are sent and received through cyclic DP communication, while the acyclic communication is
used to send additional information for system status and maintenance.
If Profibus Default Mapping is configured and a communication interruption
between a UMC (e.g. device removed) and the related Digital Gateway occurs then
all information configured in the mapping for this device will be cleared to "0".
At the same time the Life Bit for this device (always part of Default Mapping) is
cleared to 0 (1 is indicating device is communicating).
This Life Bit information for each configured device shall be used in DCS to vali-
date the Read-Data from the device. An Alarm shall be raised if Life Bit value be-
comes "0" to indicate that the communication to that single device is disturbed
and no remote control of the connected motor/load is possible any longer.
