A-B Modem NEtwork

Hi i want to comunicate like 60 plcs micrologix 1500 lsp serie B with a look out server via modem, can some body tell something, and i need to be comunicated in real time.

I have difficulty understanding your question, but I am guessing that you need to look at using the RSLinx DF1 Half Duplex Master/Slave Driver.

If you network the PLCs on an ethernet network, use Rockwell's RADES 9300 modem for connecting from a telephone line to the network. It's a dynamite little device - phone modem and ethernet switch all in one.
