■
Overview
The CP 1243-1 IEC communications processor is used to
connect a SIMATIC S7-1200 to a control center system via the
IEC 60870 protocol and has the following characteristics:
•
Support for the established communication standard in
accordance with IEC 60870-5-104 for standardized linking of
the SIMATIC S7-1200 to WinCC, PCS 7, or other commercially
available control center systems
•
Data transfer of measured values, control variables, or alarms
optimized for telecontrol systems
•
Automatic sending of alert emails
•
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
•
Data buffering of up to 64 000 values ensures a secure
database even with temporary connection failures
■
Benefits
•
Data security
The CP 1243-1 IEC 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
■
Application
By using the CP 1243-1 IEC, the S7-1200 can be used as a
remote terminal unit (substation) in telecontrol applications.
Typical uses include the collection of measured values in geo-
graphically 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
•
Traffic control systems
•
Building monitoring
•
Weather stations
•
Wind energy and photovoltaic plants
•
Environmental monitoring equipment
•
Intelligent billboards
■
Design
The CP 1243-1 IEC 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 IEC 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.
