Rated ambient from -40 to 70 °C, it sits comfortably in outdoor cabinets or unheated enclosures. The onboard 4 Mbyte integrated memory holds the user program and retains data via 480 h typical backup time on the internal capacitor, enough for extended power outages. This unit carries cULus, CE, FM, UL, and CSA approvals — a full compliance package for North American and EU panels without extra certification effort. ## Connectivity and programming Built-in PROFIBUS, Modbus TCP, UDP, and AS-Interface cover most fieldbuses without add-on comm modules. The CPU also supports FBD, LAD, and SCL programming languages. I/O addressing is 1 024 bytes each for inputs and outputs. Forcing of I/O and variables is supported.","metaTitle":"Siemens 6ES7214-1HG31-0XB0 S7-1200 CPU 1214C, 24V DC","metaDescription":"Siemens 6ES7214-1HG31-0XB0 S7-1200 CPU 1214C DC/DC/DC. 24 V DC 20.4-28.8V, -40..70°C, 4 MB memory.
