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.
