Supply tolerance is 20.4 to 28.8 V DC, so it holds through short brownouts without dropping the logic. On the network side you get PROFINET (RT/IRT capable, shared device supported), MODBUS TCP, and UDP. The integrated 4 Mbyte memory handles code and data for most discrete and batch processes without an external card. Backup time of 480 h typical keeps the program alive over weekends or shift turnover without retentive power. Programmable in FBD, LAD, and SCL; the CPU has a built-in PID controller. ## How it sits against the standard S7-1200 This is the same PLC family as the standard 1214C but with the temperature range widened from 0–60 °C to –40–70 °C and conformal coating for condensation. If your panel is climate-controlled and clean, the standard version is fine. For canning lines, compressor rooms, or outdoor pump stations, the 40 °C cold start margin and 10 °C upper headroom prevent nuisance failures. Same footprint, same I/O complement, same PROFINET port — just a different passport. Width 110 mm, height 100 mm, depth 75 mm — DIN-rail mount, same as the standard 1214C. Use 24 V DC supply rated for 20.4–28.8 V with at least 1 A for the CPU alone; add margin for any SM or CM modules on the K-bus. PROFINET cable shielded, run under 100 m twisted pair. The backup capacitor holds 480 h typical; if you need longer for a multi-week line stop, add an external 24 V battery.","metaTitle":"Siemens 6AG1214-1BG40-2XB0 SIPLUS CPU, -40 to 70°C","metaDescription":"Siemens SIPLUS S7-1200 CPU 1214C, extended temperature -40 to 70°C, PROFINET, 4 Mbyte memory, FBD/LAD/SCL.
