ABB CI773F Advant Fieldbus Configuration

Description

The master communication interface cooperates with the other communication interfaces
attached to the Advant Fieldbus 100, sharing the bus master responsibilities. To do this, the
communication interfaces must be synchronized. This is done by passing the bus mastership to
another Bus Administrator every 1024, 2048 or 4096 ms. An exception to this is during
configuration when the bus mastership might be kept for a longer time by a Bus Administrator.
During synchronization, the bus master broadcasts a checksum calculated from the current
configuration of dynamic data (scan table). The other bus administrators are able to compare
this with the checksum of their own configuration, thus checking the validity of the
configuration.
Only communication interfaces with the correct configuration are allowed to participate in the
sharing of the bus master responsibilities.

DataSet Peripherals can not be configured on the CI625 but it is possible to configure up to
100 DataSets on the module. DataSets can also be configured to the CI626 in an Advant
Controller 110 but not on the CI520/CI522 in an Advant Controller 400 Series or the
CI525/CI526 in the AdvaSoft for Windows and OPC server.
In the Advant Controller 400 Series, DataSets can not be defined for the Advant Fieldbus 100
