1. Carrier DataPort Description
The Carrier DataPort driver allows the FieldServer to transfer data to and from devices over either RS-
232 or RS-485 using Carrier DataPort protocol. The FieldServer can emulate either a Server or Client.
The DataPort device provides a gateway to CCN devices. This driver polls the DataPort device which in
turn reads data from the CCN devices. Up to 15 system elements may be connected to a DataPort
Device.
Carrier limits the number of CCN devices that can polled from a DataPort Device and also limits the data
that can be transferred between some CCN devices and the DataPort device. For information on these
limitations please consult the Carrier Corporation.
The driver is an active Client driver. This means that it initiates read polls with the DataPort device which
is expected to provide responses. Server functionality is provided by the driver too.
The driver is configured to allow a single Data Table (usually the Display Table) to be read from the CCN
devices via the DataPort device. As the table typically contains more than one data element, the
retrieved data is stored in a number of consecutive Data Array locations in the FieldServer. The driver
can provide descriptions for each of the table values retrieved.
The driver has no advanced knowledge of the CCN devices and their Data Tables. This means that the
driver handles each table in a generic way, without regard for the particular variables that constitute the
tables. The most important consequence of this is that the variable values are stored in the order in
which they appear in the response from the DataPort device. It is not possible to map particular variable
values to particular locations in the FieldServer Data Arrays.
