FS-8700-82 Carrier DataLink Page 3 of 31 1. Carrier DataLink Description The Carrier DataLink driver allows the FieldServer to transfer data to and from devices over either RS-232 or RS-485 using Carrier DataLink protocol. The FieldServer can emulate either a Server or Client. The Carrier DataLink Serial Driver allows variables to be read and written in system elements connected to a Carrier Comfort Network communication bus. Up to 15 system elements may be connected to a Data

Ensure that the device to be connected to is in fact the DataLink device and not the DataPort device which is similar looking. Configure the DataLink Device according to manufacturer’s instructions. This driver requires that the DataLink device’s DTPCONFIG table has been configured prior to connection with a FieldServer. Consult the manufa

Configuring the FieldServer as a Carrier DataLink Client It is not possible to configure communication with a DataLink device until familiar with the data available from the devices connected to the DataLink. The DataLink device does not provide a method for discovering the data tables and variables that are available in all the Carrier devices. In order to configure the Client it is necessary to know the names of the data tables availabl

The Map Descriptor is connected to a node using the node name and a node definition provides a connection to a port. Thus this Map Descriptor is connected to a port via its node. The FieldServer will use that port to send this poll which will be generated every 5 seconds. The value extracted from the respons

FS-8700-82 Carrier DataLink Page 11 of 31 4.4.5. Map Descriptor Example 2 – Read a Variable This example illustrates how to read single variables from a Carrier Device. A Map Descriptor needs to be defined for each variable. Reading variables is effective for reading a limited set of variables from a table(s). Scaling can be applied when the driver stores the value by using the additional parameters: Data_Array_Low_Scale, Data_Array_High_Scale, Device_Low_Scale, Device_High_Scale

Occupancy tables contain amongst other variables, Day of Week (DOW) settings and time settings. The driver needs to be configured so that it formats these values correctly. When the DOW write occurs, the driver extracts the value from the Data Array and converts it to a binary string whose bit value is the

Configuring the FieldServer as a Carrier DataLink Server For a detailed discussion on FieldServer configuration, please refer to the FieldServer Instruction Manual. The information that follows describes how to expand upon the factory defaults provided in the configuration files included with the FieldServer (See “.csv” sample files provided with the FieldServer).

If a client sends a read table request the driver responds by sending all the appropriate data for every Map Descriptor with the same table name (provided that the node’s match).
