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 purely for security applications if the automation system is to be connected securely to a higher-level IT network. This ensures that the SIMATIC S7-1200 is protected against unauthorized access from an Industrial Ethernet network The CP 1243-1 allows secure access via an Industrial Ethernet connection and allows the data transferred between devices or network segments to be protected from manipulation and industrial espionage.
