any PLC support DNP3 protocol? Modem question?

1.Does anybody know which PLC support DNP3 protocal? I know SCADAPACK support it, but any other PLC have same protocal?

2.May i have 2 dial up modems connect into 1 PC? One for PLC another for sending pager? If it works, are these 2 modems can dial out at the same time?

Thanks

I believe the new AB ML1400 supports DNP3 slave. See PDF below

Also SIXNET see link

As far as I know, GE Fanuc RX3i CMM modules support DNP3. The module supports up to 4 serial ports, enough to connect 2 modems for dialing out. CPU itself has additional 2 serial ports onboard. But, I've never been working with DNP3.

Thanks

Thanks. I took a look on ML1400 PLC. This PLC support DNP3 slave protocol.
I want poll from PC to PLC base on time interval, so I have to find a PLC support DNP3 protocal.
ClearSCADA tech support told me if the PC have 2 series ports, and then i can connect 2 phone line with this PC, and there is no limitation for dial out in that case (2 different channel).

Stardom FCX RTU does support DNP3 protocol.
