PLC Data Query for Freight System

Fast Automation was contracted to develop a method for querying weight and product information from a Novell server, and update data records inside a S7-400 PLC.

Technologies used:

  • Siemens S7-400 processor.
  • Siemens TP277 Touch Panels
  • Profibus, Profinet and Novell gateway software.
  • Microsoft ADODB, ADOCE and Siemens Step-7’s STL

The query was bespoke as the data from the Mettler Toledo weigh bridge was being served in a custom named and formatted flat file.
