Industrial Remote Communication
TeleControl Basic for the stations
CP 1243-1
7
■
Overview
The CP 1243-1 communications processor is used for
connecting a SIMATIC S7-1200 to the TeleControl Server Basic
control center software via Ethernet, and for secure communi-
cation via IP-based networks.
The CP has the following features:
•
Ethernet-based connection to TeleControl Server basic, e.g.
via Internet
•
Data transfer of measured values, control variables, or alarms
optimized for telecontrol systems
•
Automatic sending of alert emails
•
Data buffering of up to 64 000 values ensures a secure
database even with temporary connection failures
•
Secure communication via VPN connections based on IPSec
•
Access protection by means of Stateful Inspection Firewall
•
Clearly laid out LED signaling for fast and easy diagnostics
•
Compact industrial enclosure in S7-1200 design for mounting
on a standard mounting rail
•
Fast commissioning thanks to easy configuration using
STEP 7
■
Benefits
•
Data security
The CP 1243-1 has a large buffer for several thousand data
values. Downtimes in the transmission link can then be
bridged.
•
Fully automatic time stamp
To enable subsequent and correct archiving of process data
in the control system, all data frames are assigned with a time
stamp at their place of origin.
•
Fast and flexible data communication
Operators are therefore quickly provided with alarms, statuses
and values from the process, and they can influence process
control by entering commands or setpoints at any time.
•
Simple and low-cost engineering
The cyclic or event-controller transfer of measurements,
setpoints or alarms can be implemented in only a few opera-
tions and without programming effort.
•
Remote diagnostics
Saving of traveling and maintenance costs due to cost-
effective remote programming, diagnostics, control and
monitoring via the Internet
•
Industrial Security
Securing the system against unauthorized access by
means of
- Central access protection for any devices within an
automation cell, e.g. by means of authentication of the
network stations
- Secure remote access via the Internet by means of data
encryption (VPN) and data integrity checking
■
Application
By using the CP 1243-1, the S7-1200 can be used as a remote
terminal unit (substation) in telecontrol applications. Typical uses
include the collection of measured values in geographically
widely distributed outdoor areas (level measurement for water
tanks) or centralized opening and closing of valves (oil/gas
transport in pipelines).
•
Plants in water, wastewater or environmental sectors:
- Irrigation systems
- Drinking water supply
•
Monitoring of power networks for consumption metering and
cost control
- District heating networks
- Wind farms
•
Plants in the oil and gas sector
- Oilfield water injection
- Pipelines
•
Transportation systems
- Ventilation control in tunnel systems
- Traffic control
Regardless of the telecontrol features of the CP, it can also be
used for purely security applications if the automation system is
to be connected securely to a higher-level IT network. This pro-
tects the SIMATIC S7-1200 against unauthorized access from an
Ethernet network. The CP 1243-1 allows secure access via a
LAN and allows data transfer between devices or network seg-
ments to be protected from data manipulation/espionage.
