It handles up to 4096 digital inputs and 4096 digital outputs, so it's sized for medium-to-large process or factory lines where a single CPU failure can't shut production down. Programming languages covered include CFC, FBD, LAD, SCL, STL, and GRAPH — so whatever IEC 61131-3 dialect your team uses, this CPU runs it. It also supports MPI, RS 485, and PROFINET with TCP/IP and UDP via loadable function blocks, meaning it talks to drives, HMIs, and remote I/O without extra gateways. The module measures 50 mm wide, 290 mm tall, and 219 mm deep. It clips into a full-height subrack. ## Fault-tolerance and communication limits The FM and CP expansion is limited by slots and connections per the manual. PROFIBUS supports DPV0 and DPV1; PROFINET handles TCP/IP and UDP routing. System functions available include RDREC, WRREC, RDSYSST, and — all with the counts shown in the spec table. Forcing is supported, which is useful during commissioning but less common in production fault-tolerant systems.","metaTitle":"Siemens 6ES7414-5HM06-0AB0 S7-400H CPU, 4096 I/O","metaDescription":"Siemens 6ES7414-5HM06-0AB0 S7-400H fault-tolerant CPU.
