Web function block in automation equipment
First Claim
1. Communication system for automation equipment (10) acting on a TCP/IP network (50) in which the automation equipment (10) controls an automation application by executing an application program (20) written in one or several languages according to standard IEC 1131-3, characterised by the fact that the communication system comprises:
- exchange means for implementing a WEB server function or a WEB client function inside an application program (20), these exchange means comprising at least one WEB function block (21, 22) that can interact with the application program (20), an HTTP interface (15) in the automation equipment (10) capable of routing messages from the TCP/IP network (50) to a WEB function block identified by a URL address, and routing messages from a WEB function block in the automation equipment (10) to a URL address on the TCP/IP network (50).

Abstract
This invention relates to a communication system for automation equipment (10) on a TCP/IP network (50). The automation equipment (10) controls an automation application by executing an application program (20) written according to standard IEC1131-3. The communication system comprises at least a reception WEB function block (21) integrated into the application program (20) to implement a WEB server function and/or at least one send WEB function block (22) integrated into the application program (20) to implement a WEB client function and an HTTP interface (15) capable of routing messages between the TCP/IP network (50) and WEB function blocks identified by a URL address. The contents of HTTP requests may be an XML frame or a URL encoded frame.
