■
Overview
The CP 1242-7 communications processor is used to connect a
SIMATIC S7-1200 to the globally widespread GSM/GPRS mobile
radio network and has the following characteristics:
•
Worldwide wireless exchange of data between S7-1200
controllers and/or between S7-1200 controllers and control
centers with an Internet connection
•
Communication based on the GPRS (

S
ervice) mobile wireless service with data transmission
speeds of up to 86 Kbit/s in the downlink and 43 Kbit/s in the
uplink
•
GPRS mode with fixed IP addresses and dynamic IP
addresses with standard mobile phone contract
•
Time synchronization on the basis of NTP (

•
On-demand connection buildup via voice call or text message
•
Sending and receiving of text messages
•
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
In conjunction with the TeleControl Server Basic software, the
CP 1242-7 forms a telecontrol system with additional properties:
•
Connection of up to 5 000 telecontrol stations to the control
center via an OPC interface
•
Data buffering in the substations in the event of connection
failures
•
Central status monitoring of the substations
•
No special provider services required for fixed IP addresses
•
Teleservice access with STEP 7 to the substations via the
Internet
■
Benefits
Connection of the S7-1200 to a mobile wireless network turns the
controller into a telecontrol substation (RTU - Remote Terminal
Unit) suitable for universal use.
•
Data connection of difficult-to-access areas without high
network infrastructure costs since the existing mobile wireless
network can is used
•
Machine maintenance without complicated integration into the
end customer's IT networks
•
Reduced maintenance and travel costs thanks to centralized
management of remote automation solutions
The CP 1242-7 has been specially developed to meet the re-
quirements of telecontrol systems in automation solutions:
•
Avoidance of data loss thanks to rugged connection to the
control center and buffering of the data
•
Fast commissioning thanks to direct configuring using STEP 7
■
Application
•
Data exchange and centralized data monitoring for
automation solutions spread over large geographical areas
•
Establishment of permanent or temporary communication link
for mobile machines/vehicles without permanent location
•
Global remote access to the end customer's machinery in
compliance with IT security requirements
•
Connection of difficult-to-access external stations without a
network infrastructure
These applications can be found in the most diverse sectors:
•
Water/wastewater treatment plants – pump/valve controllers
•
Traffic and transportation – traffic light controls, lighting
controls
•
Power engineering – monitoring of transformer stations, meter
readout
•
Mechanical engineering – centralized remote maintenance of
machines used around the world
•
Wind energy – condition monitoring of wind turbines
•
Vending machine manufacturers – monitoring, control of
beverage vending machines
