 Modifying the registers address and (re)organize the data memory to optimize
the Modbus master/client treatment.
 Feeding the fire system configuration into the Modbus master/client
configuration tool.
The following fields (columns) are present in the CSV file:
SubsystemId
Identifier of the subsystem in the Composer project, and used during file re-import.
It cannot be modified.
NodeId
Identifier of the node in the Composer project, and used during file re-import. It
cannot be modified.
WARNING
Composer subsystem and node IDs are used during the re-import to identify the
object positions. Any modification to those fields in the imported file are likely to
cause the system to fail.
FieldDevice
Description text of the control unit. Modifications to this field are ignored in the re-
import.
ModbusSlaveAddress
Address of the Modbus slave (range: 1… 247). Modifications to this field are
ignored in the re-import.
ParentDescription
Description text of the parent object. Modifications to this field are ignored in the re-
import.
Description
Description text of the object. Modifications to this field are ignored in the re-import.
TechnicalText
Technical text of the object in the Composer project. Modifications to this field are
ignored in the re-import.
ObjectName
Unique technical tag of the object. It cannot be modified.
ModbusTable
Name of the table in the Modbus data representation (see FS2xxx Register Map
[➙ 16]). It cannot be modified.
Modbus BaseAddress
Starting address of the set of Modbus registers associated to the object.
Modifications to this field are ignored in the re-import. However, note that the base
addresses can be modified in the Composer configuration.
For each object, the current Modbus register address is determined by the sum of
Modbus BaseAddress and ModbusAddress.
