The 24 V DC supply accepts 20.4 V to 28.8 V, so it rides through a sagging 24 V bus that would brown out a tighter-range controller. Programming in FBD, LAD, or SCL is supported, and the onboard PID controller handles closed-loop tasks like temperature or pressure regulation without an extra module. The PROFINET interface (TCP/IP, server-capable) connects directly to an upstream controller or HMI — no extra communication processor needed. Note that this CPU does not carry MODBUS or PROFIBUS on the onboard port; those protocols require a separate communication module if the existing line uses them. The 1024-byte input and output process-image areas are adequate for a compact machine with a handful of remote I/O drops. ## Memory and backup — what stays when the power goes The 1 Mbyte integrated load memory holds the program, and the entire project is maintained in the integral EEPROM — no battery-backed RAM to fail in storage. The typical backup time of 240 hours means the real-time clock and retentive tags survive a weekend shutdown without the power supply connected. The bit memory address area is limited to 4 kbyte, which is the standard for this CPU class and sufficient for most machine-state flags.","metaTitle":"Siemens 6ES7212-1HD30-0XB0 CPU 1212C, 1 MB memory, PROFINET","metaDescription":"Siemens 6ES7212-1HD30-0XB0 CPU 1212C with 1 Mbyte integrated memory, PROFINET interface, 24 V DC supply. cULus, CE, FM approved.
