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.
You can use the STEP 7--Micro/WIN Modem
Expansion Wizard to configure an EM 241
Modem Module. See Chapter 10 for more
