HTTP client

11.1 HTTP client

The FP Web-Server is able to act as a HTTP client. Two http request

standard methods are supported: HTTP GET and HTTP POST.

HTTP GET:

The FP Web-Server sends a HTTP GET request to the HTTP server. The

HTTP server sends its response to the request to the FP Web-Server. If the

FP Web-Server receives a response, it will write the response to the PLC. If

no response is received, an error flag will be set.

Possible applications are for example:



Read files (e.g. logfiles) from the own expansion unit (using the FP

Web-Server's own IP address or 127.0.0.1) .



Read files (e.g. logfiles) from an external HTTP server.



Read PLC data from an external FP Web-Server.



Find out your external IP address (dynamical IP addresses) by sending

a GET request to e.g. http://my.ip.fi/ or http://ifconfig.me/ip.



Set PLC internal flag bits or PLC outputs by sending a GET request.
