SYSTEM RELATIONSHIP
Where 6GK7243-1BX30-0XE0 Fits
Functional role The CP 1243-1 adds an Industrial Ethernet interface to a SIMATIC S7-1200 station and supports control-center communication through DNP3, IEC 60870 and TeleControl Basic. Integrated firewall and VPN functions support protected remote connectivity.
Family comparison Compare CP 1243-1 with other S7-1200 communication processors by supported control-center protocol, Ethernet topology, security function and engineering compatibility. A standard CPU Ethernet port or unmanaged switch does not provide the same telecontrol role.

Customer Commitment Responsive support for current and discontinued industrial automation parts.
Careful Matching Complete article-number checks support confident maintenance planning.
Global Cooperation A broad network helps reduce delays and production downtime.
Can 6GK7243-1BX30-0XE0 be used only as a second standard Ethernet port?
Its intended value is telecontrol and protected remote communication. Confirm the control-center protocol and security architecture instead of treating it as a generic network expansion.
02
What must be matched before replacing 6GK7243-1BX30-0XE0?
Match the complete article number, hardware and firmware context, CPU compatibility, configured protocol, project version, IP plan, VPN and firewall settings.
03
Does 6GK7243-1BX30-0XE0 need a separate 24 V DC supply?
The module receives 5 V DC from the S7-1200 backplane. The complete station power budget still needs to include its typical 0.25 A consumption.
04
Which installation detail matters for 6GK7243-1BX30-0XE0 temperature limits?
The permitted operating temperature depends on mounting orientation, reaching +70 deg C horizontally and +60 deg C vertically.
05
What should be included in a 6GK7243-1BX30-0XE0 quotation request?
Provide the CPU article number, protocol, engineering version, required quantity, hardware condition and destination so compatibility can be reviewed accurately.
