Programs in LAD, FBD, and SCL; communicates via PROFINET as a server over Ethernet TCP/IP. No onboard MODBUS, PROFIBUS, or AS-Interface. The CPU is not expandable — it has no slot for signal modules. I/O capacity is fixed at 1 024 byte inputs and 1 024 byte outputs, plus 4 kbyte bit memory and 15 dynamic connections. ## Rated range and cold startup Supply hold-up: backup time for the real-time clock and data retention is 240 hours typical, enough to bridge a long weekend without power. The input signal thresholds are defined at 5 V DC at 1 mA for logic '0' and 15 V DC at 2.5 mA for logic '1' — that callout matters when mixing 24 V sensors with longer cable runs where voltage drop can border the '1' threshold. The IP20 enclosure requires installation inside a closed cabinet free of condensation. PROFINET interface autocrosses, so no crossover cable needed.","metaTitle":"Siemens 6AG1212-1HD30-4XB0 SIPLUS S7-1200, -40 to 70°C","metaDescription":"Siemens SIPLUS S7-1200 CPU 6AG1212-1HD30-4XB0 with 24V DC range 20.4-28.8V, -40..70°C, 1MB memory, PROFINET. cULus.
