Dear All,

Iam looking for a GSM Modem with RS-485 Interface. I want to Interface PLC data to a remote PC over GSM modem. Are there any manufacturers/supplier available? Please help me out.

With Best Regards,
SANJEEV

 

Hi Sanjeev,

I dont know any GSM modems with a RS485 interface, but I guess you could use for example the MD-45 RS485 to RS232 converter and the GD-01 GSM modem from Westermo. You can find more info on http://www.westermo.com

You would need a converter (RS485 -> RS232) with the ability to dial-in or out via GSM modem.

Check out SAN People PPP products:

Routing functionality allows you to connect remote networks via its Ethernet interface. You could have a number of PLCs on Ethernet connected to a GSM modem.

What protocol is your PLC setup for? Converters support extras (e.g. Modbus Bridge).

Hope this helps.
