It supports FBD and LAD programming with failsafe functions baked in — meaning you can build safety logic without a separate safety controller. Temperature range covers -40 to 70 °C, so it handles cold storage rooms or hot enclosures without active cooling. ## Communications and memory Built-in PROFINET interface with autocrossing and autonegotiation. Also supports MODBUS TCP, UDP, and AS-Interface — you've got network flexibility without extra modules. The 4 MB integrated memory holds your program and retains data for 480 hours at 40 °C (12 days min). That's enough to ride out a long weekend power loss without reloading. Need PROFIBUS? Add the CM 1243-5 module. No PROFIsafe on this CPU, so safety communication stays hardwired or via F-host. ## I/O and analog inputs Process image supports 1 024 bytes each for inputs and outputs. Isolated 0-10 V analog input is adjustable. Digital input thresholds: signal 0 at 5 V DC at 1 mA, signal 1 at 15 V DC at 2.5 mA. Output forcing supported. Marine approval is on the specs sheet — good for shipboard or offshore panels.","metaTitle":"Siemens 6AG1214-1AF40-5XB0 Failsafe CPU","metaDescription":"Siemens 6AG1214-1AF40-5XB0 failsafe CPU supports FBD/LAD with failsafe, 24 V DC, -40 to 70 °C, PROFINET, 4 MB integrated memory with 480 h backup.
