Channel Mapping

With the channel mapping you have the possibility to map channel names from channels in files to another choosen standard name. You can also map a standard unit on a channel, if its name is mapped. The only thing to do before, is to create two simple text files. One for global and one for local channel mapping. The files consist of comma-separated entries. The channel mapping service works has an option to work case-insensitive in newer version (beginning with version of jBEAM). That means that the channel mapping even works if you define “abc” in your channel mapping file, but the channel of the import is named like “ABC” or “AbC”. You can enable this mode in the preferences dialog of jBEAM.

Structure of the file:

"Standard name1", "Standard unit1", "Actual name11", "Actual name12", any number of other
"Standard name2", "Standard unit2", "Actual name12", "Actual name21", any number of other


"My time","s","Time","Date-Time"
"Engine speed","1/min","Rotational speed","DRZ"
"Engine torque","Nm","EFFMOMT"

If the unit should be null write this:

"Standard name1", , "Actual name1", ...

The first entry is the standard name, you want to map to. The second entry is the standard unit. The third and further following entries stands for the channel names from file.

You can find the settings for the channel mapping in jBEAM under the menu item Edit -> Preferences -> tab Importer -> tab Channel mapping.


  • two files can be defined (global and local file)
  • if only one file is defined, this one is used
  • if both files are defined and for one channel the standard name and the standard unit is defined in both files, so the local definition is used

The following list shows the file importer, which actually support the channel mapping:

  • Bosch-Injektor
  • BEAM
  • DIAdem
  • Excel
  • Gidas
  • PAtools
  • NetCDF
  • MDF
  • Yokogawa

The character set of the cmap files should be UTF8 with BOM.
