PLC5 TO ORACLE

[rubha]

Anybody have experience communicating between Oracle and a PLC5? What did you use for the interface?

Thanks in advance

With any interface their should be an PLC to Host interface specification. You might want to get ahold of this or maybe its your responsible for creating it. Your question is very broad, not sure what your asking for.

Once you have created this document then you should be able to write code to this interface.

Most PLC to Host Hardware Interfaces for PLC5 are either the dated DH+ or more up to date Ethernet/IP.

Most of the messaging back and forth has a header (what message is this) content (what info are you passing) acknowledge the message (some way to verify it got to its destination)

You could use DDE/OPC topic to excell or access then to oracle. This would be done using rslinx pro or some other dde/opc server. Or run a rsview32 app and datalog to oracle.

If you are familiar with Visual Basic 2005 or 2008 , then you can use this software to connect to the serial port and easily transfer data between the PLC5 and the Oracle DB:

Visual Basic Express is a free download as well as the DF1 component.

This gives an idea of how to get started with the PLC comms, but not the Oracle connection:
