Have a good day everyone ! 

My name is Son, come from Viet Nam

I am working on PLC S7-1500 project and I got a problem need to your helps

I have a S7-1500 station, it already have HMI and PC station for SCADA from here yet, But It is on mobile crane and no have LAN network for it.

And now, We want to connect to this S7-1500 station from another place far away (office or any places else) , because here we dont have a LAN network, dont have the STATIC IP to publish on Web.

So, i have read some document from Siemens and got a solution using TIM 1531 IRC communication module and SCALANCE M874-3 (3G) for this, protocol is SINAUT ST7cc. That solution for S7-1500 system.

Have you ever done about that problem????

Please give me advises, or your experiement about this project

Here are some picture about our project.

Thanks all :D 

please, help me!!!

Anyone can support this problem?

Hi,

I think this solution should work. Take a look to this application example:

Connection of an S7 1200 RTU, an S7-1500 and an ET 200SP RTU to a ST7cc central station

You can use (for example) a "Scalance M816-1" for wireless connection.
