It supports LAD, FBD, and SCL programming languages and communicates via PROFINET (no Modbus or PROFIBUS). Integrated 1 MB work memory and a typical 240 h backup for the real-time clock mean program and RTC data persist through extended power-offs. The process image is 1 024 bytes each for inputs and outputs. ## Memory, compliance, and sourcing Rated for cULus, UL, and CE mark, this CPU carries the approvals expected for a global panel build. ## Mounting dimensions and connection notes Width 90 mm, height 100 mm, depth 75 mm — fits the standard S7-1200 footprint. DIN-rail mount, same profile as the basic CPUs. PROFINET interface with autonegotiation and autocrossing (MDI/MDIX). No fieldbus expansion available (AS-Interface, PROFIBUS not supported onboard). Ethernet connection is TCP/IP. Forcing and full program upload/download supported. Remanent data uses the integral EEPROM for maintenance-free retention.","metaTitle":"Siemens 6AG1212-1BD30-4XB0 S7-1200 CPU, -40 to 70°C","metaDescription":"Siemens SIPLUS S7-1200 CPU with PROFINET, 1 MB memory, 1024 I/O bytes, rated -40 to 70°C.
