Cell protection for SIMATIC S7-1200 with CP 1243-1 (Security Integrated)
■
Design
The CP 1243-1 offers all the advantages of the S7-1200 design:
•
Rugged, compact plastic enclosure
•
Easily accessible connection and diagnostics elements,
protected by front flaps
•
Simple mounting on the mounting rail of the S7-1200
The CP 1243-1 DNP3 is plugged into the left-hand system
bus interface of the S7-1200. Power is supplied directly via the
S7-1200. No additional wiring is necessary. Any required
modems or routers are connected via the Ethernet interface
on the underside of the module.

The CP 1243-1 is a communication module for the S7-1200.
The module allows the S7-1200 to be connected as a remote
station to TeleControl Server basic in just a few steps.
Completely configurable application through
"data point configuration"
The introduction of the "data point configuration" in STEP 7
dispenses with all programming effort for transfer of data to the
control center.
The data of the CPU relevant to the control center is selected via
user-friendly "item browsing" in STEP 7. In a clearly-arranged
menu, the data transfer parameters are then assigned to the
data points selected in this way. The cyclic or event-controller
transfer of measurements, setpoints or alarms can thus be
implemented in only a few operations and without programming
effort.
Data backup
Data losses are prevented by the data buffering mechanisms
integrated in the product.
In the event of a connection failure, up to 64,000 time-stamped
values are buffered. When the connection returns, the buffered
values are automatically transferred to the control center in the
right order.
E-mail alerting
Alert e-mails can be configured for timely provision of stations'
states to service or maintenance personnel. If previously defined
events (such as threshold violation) should occur, application-
specific information is sent automatically by e-mail.
Diagnostics
The CP 1243-1 offers comprehensive diagnostic options for a
quick and informative analysis of the station status. Elementary
diagnostic information about the connection to the control center
is signaled directly via LEDs at the CP.
Using STEP 7, comprehensive information can be retrieved,
such as connection history, buffer status, and the transferred
measured values.
Remote maintenance
For remote access from the control center to the substation, the
CP provides a remote maintenance port in parallel with process
operation. This ensures access for monitoring and program
changes.
Interfaces
The CP 1243-1 has an Ethernet interface to connection to the
control center. The S7-1200 can be connected via an existing
network or via other media by using additional routers (e.g.
SCALANCE M for Internet connection via DSL).
Power supply
Extra wiring for the CP power supply is not required. Power is
supplied directly via the backplane bus of the S7-1200.
