Modem communication
Modem communication means that the
S7-200 CPUs can be accessed almost
worldwide using standard commercial
modems.
• Teleservice: modem communications
• Telecontrol: Remote interrogation of
Fast on the PROFIBUS
All CPUs from 222 upwards can also
be operated as a slave on the
PROFIBUS-DP network using the
EM 277 communications expansion
module. The EM 277 expansion
module gives you the flexibility to add
PROFIBUS-DP communications, as you
need it – when you need it.
Powerful on the AS-Interface
The CP 243-2 turns the CPUs from 222
upwards into powerful masters on the
AS-Interface. Up to 62 stations can be
connected according to the new AS-i
specification V 2.1. Analog sensors can
also be linked without problem.
According to the new AS-i specification,
up to 248 DI + 178 DO can be connected
in the maximum configuration. 31 of the
max. 62 stations can be analog modules.
means that expensive service visits can
be avoided. Only two additional
modems are required in order to use
the complete programming functions
such as program transfer, status or
control; the communications tools
are standard.
messages and measured values is
possible via modem, just as the input
of new set points or commands.
A headend can control a number of
substations. Communications using
FreePort using the SMS function
directly to a cell phone is possible or
alarms to a fax unit.
