The EM 241 Modem Module replaces the function of an
external modem connected to the communications port
of the CPU. With an EM 241 installed in your S7-200
system, all you need to communicate with your CPU
from a remote location is a personal computer with an
external modem and STEP 7–Micro/WIN.
See Chapter 7, Communicating over a Network, for
information on configuring. See Chapter 10, Creating a
Program for the Modem Module for programming and
advanced features of the module.
