Mapping
Due to the dynamic device configuration that is available, the Modbus mapping needs to be exported from
the NXTSD507HD or NXTSD512HD as a .csv file. This file will show the following:
•
Server address in 4x format
•
Connected device name (name assigned during device configuration)
•
The original Modbus address of the source data (from the original device documentation)
•
A description of the data
•
The gain, which indicates if the data needs to be divided
•
How many registers the data occupies
•
The data type (signed, unsigned, etc.)
•
If the data is writable
To export the data, navigate to the

page and press the button “Export Tags”. This button will only be shown if there is a USB drive installed.
The data will be exported to the USB drive as two files:
•
FireyeHMI\Export\EnumMap.csv
, which shows enumerations for registers that contain values
based upon a state.
•
FireyeHMI\Export\MBServerMap.csv
, which shows the complete list of registers present for all
connected devices. See the specific device bulletins for additional information on what each
register represents.
The resulting .csv files can be read with any text editor or a spreadsheet program such as Microsoft Excel.
Below is an example of MBServerMap.csv, viewed using Microsoft Excel:
In this case, the device named “Boiler 1” is a PPC4000 so this must also be known since there can be
multiple devices present.
