Supply voltage L+ minus 4 V DC min. Operating temperature -40 to 70 °C.","salesMarkdown":"The 6ES7212-1AE40-0XB0: Standard CPU from the S7-1200 family with 2 Mbyte of integrated work memory, enough for moderate logic and data handling. No PROFIsafe on board; safety integration needs a separate F-CPU or fail-safe signal module. OPC UA server is built in, so transparent data exchange with higher-level systems is available without an extra module. DCP and LLDP are enabled for network configuration. Communication portfolio covers MODBUS TCP, UDP, TCP/IP, and PROFIBUS via a CM 1243-5 (master) or CM 1242-5 (slave). 34 reserved connections with room to expand to 64 total under software configuration. Supply voltage must be 24 V DC, tolerance down to L+ minus 4 V DC. Operating range -40 to 70 °C covers most industrial environments. Programming languages: LAD, FBD, SCL. The CPU supports forcing variables for commissioning, and the ERROR and MAINT LEDs give local diagnostics. ## Certifications Carries both CE and cULus marks, covering the European and North American markets.","metaTitle":"Siemens 6ES7212-1AE40-0XB0 S7-1200 CPU, 2MB Work Memory","metaDescription":"Standard S7-1200 CPU with 2 Mbyte work memory, OPC UA server, MODBUS TCP, PROFIBUS via CM.
