Communication line configuration


  • Communication line category: FILE I/O.
  • An input file is a file generated by X-ray analyzer, which contains the chemical composition of raw materials.
  • Archive directory is a directory which contains the input files. The files are moved there under new name after analyzing by this protocol.

Communication station configuration


  • Communication protocol: RFE
  • Station address is a name of raw material (measuring method).

I/O tag configuration


I/O tags: AI, DI, TxtI

The address of I/O tag is the name of oxide.

The value of I/O tag is a percentage of oxide in the raw material.


Error handling

The error handling (when analyzing the input file) can be done when you configure a special station with the special I/O tags. The protocol can provide the detail information about error with the help of these points.

The value of I/O is TxtI:

  • Station address - RFE_ERRORS
  • I/O tag addresses:
    • FILE_TIME_ERROR - date of input file is out of range. The range is set on the current time ± 12 hours.
    • UNKNOWN_MATERIAL - any station address does not respond to the loaded measuring method (the value is formed by the names of unknown method separated by semicolon).
    • UNKNOWN_OXID - any I/O tag address does not respond to the loaded oxide (the value is formed by the names of unknown oxides separated by semicolon).
