The backplane provides 5 V at 0.06 A typical for internal logic. Tolerance is -15% to +20% on the 24 V rail. ## Software and configuration This module requires STEP 7-Micro/WIN Version V3.2 SP1 or higher for configuration — older versions won't see it. No SNMP v1 support and no web-based diagnostics, so plan on using the Siemens configuration tool or a Modbus TCP client for monitoring. The module supports TCP/IP but not SNMP, so network management tools that rely on SNMP polling won't get MIB data from this port. ## Environmental limits Operating range is 0 to 55 °C horizontally or 0 to 45 °C vertically mounted. The 1.75 W power loss is modest — no special ventilation required in a standard IP20 enclosure, but keep it away from heat sources like drives or power supplies that could raise internal cabinet temperature above 55 °C.","metaTitle":"Siemens 6GK7243-1EX00-0XE0 CP 243-1 Ethernet, 10/100 Mbit/s","metaDescription":"Siemens CP 243-1 communications processor for SIMATIC S7-22X. 24 V DC, 10/100 Mbit/s Industrial Ethernet, RJ45, IP20.
