The CP 1243-1 communications processor is used for connecting the SIMATIC S7-1200 to telecontrol centers via remote networks and telecontrol protocols (DNP3, IEC 60870-5-104, TeleControl Basic), and for safe communication 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 via 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
