It supports FBD, LAD, and SCL programming languages, so you can migrate ladder logic from an S7-200 or write structured text for a new sequence without switching editors. The 2 MB integrated memory and 8 kbyte bit memory address area handle moderate-size programs, and the entire project is retained in the integral EEPROM — no battery worry for the program itself, though the 240-hour typical backup time covers volatile data during a power loss. ## I/O capacity and field wiring It addresses 1,024 bytes of inputs and 1,024 bytes of outputs — enough for a machine with a couple of remote racks plus local I/O, but not expandable beyond that via local modules. The forcing function lets you override I/O states during commissioning or fault-finding without changing the program — useful when you need to test a prox sensor circuit before the machine cycles. It supports 2-wire sensors with a signal \"1\" threshold of 15 V DC at 2.5 mA, so standard 24 V proximity switches work without a separate power supply for the sensor loop. ## Environmental and compliance fit Rated for -40 °C to 70 °C ambient, this PLC can sit in an unheated warehouse or a hot cabinet near a drive without derating — the full temperature range is listed, not a reduced commercial grade. It carries cULus, CE, and UL approval marks, so it meets the common North American and European certification requirements for industrial control panels. Dimensions are 110 mm wide, 100 mm high, and 75 mm deep — a compact footprint that fits most DIN-rail enclosures without needing a wider panel cutout. ## Communication and control capabilities Built-in TCP/IP support with autocrossing means you can plug into a standard switch or directly to a laptop with a straight-through cable — no crossover cable needed. It can act as a web server, allowing remote monitoring of inputs/outputs, memory bits, DBs, distributed I/Os, timers, and counters through a browser — handy for checking machine status from the office. An integrated PID controller is on board, so you can close a loop on temperature or pressure without an external module, though the number of loops is limited only by the available RAM for code. No PROFIBUS or AS-Interface on this unit — it's Ethernet-only for fieldbus, so if your plant floor runs on those older networks, you'll need a gateway or a different CPU.","metaTitle":"Siemens 6AG1214-1HE30-4XB0 PLC, 24 V DC, 2 MB Memory","metaDescription":"Siemens 6AG1214-1HE30-4XB0 PLC, 24 V DC supply, 2 MB integrated memory, FBD/LAD/SCL programming, -40 to 70 °C, cULus, CE.
