Embedded file system for a programmable logic controller
First Claim
1. A server operably connected between an industrial programmable logic controller and a network for storage of web pages and programs comprising:
- a memory device for storing the web pages and programs;
an FTP server operably connected to the memory and the network for uploading the programs into the memory from the network;
an HTTP server operably connected to the memory and the network for downloading the web pages from the memory onto the network;
a TCP/IP stack operably connected between the network and the FTP and HTTP server; and
, means for allowing the industrial programmable logic controller access to the memory for downloading the programs into the industrial programmable logic controller, the industrial programmable logic controller being operably connected to an input/output module wherein a communication link facilitates bi-directional exchange of signals between the input/output module and an associated device.

Abstract
An apparatus is provided for storage of applications symbols, graphics, web pages, and other data within a server coupled to a programable logic controller. The server is operably connected to a network and the programable logic controller and includes a memory, an FTP server, and a HTTP server. The FTP server is operably connected to the memory and the network for transferring files into the memory. The HTTP is operably connected to the memory and the network for transferring web pages onto the network. Also, the programable logic controller is provided access to the memory within the server for downloading files into the memory of the controller.
