Setpoint Source File

With setpoint source File, the setpoints are available in the form of a file on the process control unit (PCU) drive. By default, this directory is <PXI IP address>\patools\dat.

The file is available in the following formats:

  • Erg
  • EDAS32
  • DIAdem
  • PAtools-Binary
  • MATLAB
  • MDF4
  • CSV

During parameterization, certain channels from the file are referenced by their name as a setpoint track for the following setpoints:
  • Time
  • Current
  • Voltage
  • Power
Either a current setpoint or a power setpoint can be assigned. If a power setpoint is assigned, the current setpoint is used as the limit value. In this manner, the channel Time.Ref refers to a reference track for time. The channel I.Ref refers to a reference track for current.
Note EDAS 32 files must be present in the following format: linear data organization and REAL 32bit block and numeric formatting.
Note The following DIAdem file formats are supported:
  • REAL* (* = 32, 48, 64)
  • INT* (* = 16, 32)
  • WORD* (* = 8, 16, 32)
The *.dat is specified as a file name. The *.r32 or *.r64 must reside in the same directory.
