The Siemens 6GK7243-1BX30-0XE0 CP 1243-1 is a communication processor that adds a second Ethernet interface to a SIMATIC S7-1200 CPU and connects the station to a control center over telecontrol protocols including DNP3, IEC 60870-5, and TeleControl Basic, over a single 10/100 Mbit/s RJ45 port. It also provides a stateful-inspection firewall and IPsec VPN with up to 8 connections for secure remote access.

Selection Notes
DNP3 and IEC 60870-5 support are what separate the CP 1243-1 from a standard S7-1200 integrated Ethernet port, so it is the module to add when a station must report to a SCADA control center over a recognized telecontrol protocol rather than plain TCP/IP. Up to 3 units per CPU allows redundant or multi-path reporting paths from a single controller. The 64,000-event data buffer means readings keep accumulating during a connection outage instead of being lost, which matters for unattended remote sites with intermittent links. Eight concurrent IPsec VPN connections with AES-256 support secure remote engineering access without a separate VPN appliance.
Applications
Remote telecontrol reporting from pump stations, substations, and unmanned sites to a SCADA control center via DNP3 or IEC 60870-5; secure VPN-based remote access and diagnostics for distributed S7-1200 installations; MQTT connectivity to cloud platforms.
