It supports LAD and FBD programming with failsafe libraries, so a single CPU handles the machine logic and the safety interlocks without a separate safety relay or redundant controller. PROFIsafe communication is built in as both client and server, meaning this CPU can exchange safety telegrams directly with remote F-I/O or drives over PROFINET. No additional gateway needed for safety-over-Ethernet. ## Fieldbus and protocol flexibility Native support for MODBUS TCP/IP and UDP covers the common plant-floor protocols. For legacy PROFIBUS networks, an external CM 1243-5 module is required. Media Redundancy Protocol (MRP) is supported as a client, so the CPU can be part of a ring topology that self-heals on a cable break — typical for production lines where a single fault cannot be allowed to drop the network. LLDP and SNMP enable standard network management and topology discovery, useful for commissioning and asset tracking. ## Environmental range and power requirements The 24 V DC supply must stay above L+ minus 4 V DC minimum; a 24 V rail that dips below 20 V during a motor start will cause a brownout. The backup time for retentive data is 480 h typical — enough to ride through a long weekend shutdown without losing counters, timers, or recipe values. ## Memory and I/O configuration Integrated 4 Mbyte memory stores the user program, data blocks, and the system firmware. The bit memory address area is limited to 8 kbyte, but the full set of forced variables and online diagnostics are available. 16 digital inputs are on-board, dynamically configurable — the same physical terminals can be set as sink or source depending on the field wiring, which saves a terminal block when mixing sensor types. Analog inputs support 0 to +10 V and 0 to 20 mA with adjustable ranges, making it straightforward to connect pressure transmitters, temperature probes, or flow meters without external signal conditioners.","metaTitle":"Siemens 6AG1215-1AF40-5XB0 S7-1200 CPU, PROFIsafe, 16 DI","metaDescription":"Siemens 6AG1215-1AF40-5XB0 S7-1200 CPU with PROFIsafe, 16 digital inputs, 4 MB memory, -40 to 70 °C.
