send http line to website

Hi All

Is it possible to send a HTTP line to a certain website like

for example: http://www.mywebsite.com/data.php?variable1=value1&variable2=value2

or if not is it possible to send it to an extern IP adres that is not in the same subnet as the PLC

can somebody show me an example if it is possible.

Hi Huggy

What i want to do is to send this line to the internet.

nothing more, nothing less.

I do not want a response back

If it is possible

Can you make an example for me

i tried it, but i only can do it when it is in the same subnet and i only can send data, and not the total line.

 http://www.mywebsite.com/data.php?variable1=value1&variable2=value2

Hi huggy

Thanks for your answer, but it is not really helping me.

I know everything on the http site.

i am missing info on how to send it from the plc

can somebody make a simple program how to do this.

The initiative of sending the http line is made by the PLC himself.

So there is no request from the outside for the info.

 Hello

Please have a look at this sample program.

S7-1200 TCP communication - Sample program

It should be possible to use this program ( With slight modifications ) to communicate between a S7-1200  and any other partner.

Basically you need to do the following :

a) Create a DB with a Character array
b) Configure the connection using TCON_C Block
c)  Transmit the character array using the TSEND_C block.

We have used this method to send / receive data from 40 different S7-1200 in remote areas to a common server.

The following document will also help you in understanding the basic concepts of TCP communication between PLC and PC ( Web server in your case )

The guide about TCP/IP connections between PC’s and PLC’s

Hope this helps

 Hi, I would like to consult you if you could do it?

I give this post again a kick.

For me this issue is still not solved.

as mentioned i want to send a line to the www. 

the line should be http://www.mywebsite.com/data.php?variable1=value1&variable2=value2

I can not send to an IP adress because the mywebsite.com is on a shared server.

again the question if this is possible.

At this moment i am using an interface module (arduino) to do this. but i am not so happy with it. 

Maybe now a few years later somebody has worked out a solution and is willing to share it.
