CP 1243-7 LTE is used to connect the S7-1200 to a mobile wireless network of the 4th Generation LTE (Long Term Evolution). The increased data rates compared to GPRS and widespread introduction of LTE open up new areas of application. The CP1243-7 is characterized by the following properties:

• 1 connection to LTE (4G) mobile wireless network
  (various versions for EU and North America)
• Data transfer of measured values, control variables, or alarms optimized for telecontrol systems
• Operation with fixed IP addresses and dynamic IP addresses with standard cellular phone contract
• Time synchronization based on NTP (Network Time Protocol)
• On-demand connection buildup via voice call or text message
• Sending and receiving of text messages
• TeleService access with STEP 7 to substations via mobile wireless networks
• Compact industrial enclosure in S7-1200 design for mounting on a standard mounting rail
• Temperature range in operation: -20°C to +70°C
• Installation on standard mounting rails
• Diagnostics LEDs (overall status and details)
• Integrated security functions (VPN and firewall)
• Access to the CPU Web server
• Fast commissioning due to simplified configuration with STEP 7
• Data buffering of up to 64,000 values ensures a secure database even with temporary connection failures
