It supports the full IEC 61131-3 language set: CFC, FBD, LAD, SCL, STL, and GRAPH, plus MPI and RS 485 for local programming and peer-to-peer links. The CPU is isolated and carries cULus and CE marks, plus ATEX II 3G Ex nA IIC T4 Gc for use in Zone 2 gas environments — a rare combination on a S7-400 CPU that simplifies panel certification for combined industrial and hazardous-area lines. ## Interface limits and communication capacity Each external interface supports up to 8 (SFC 59) and 8 (SFC 58) operations, and 8 RDSYSST calls; the DPV1 interface handles 8 RDREC (SFB 52) and 8 WRREC (SFB 53) per interface, with a global cap of 32 across all external interfaces. Up to 4 CP443-1 Ethernet processors are allowed in the central controller, but mixed operation of CP443-1 EX40 with EX41/EX20/GX20 is prohibited. Point-to-point CP 440 and CP 441 modules are limited by slot count and connection count respectively; the CPU itself does not impose a hard cap beyond the rack's physical limits. ## Process image and I/O addressing The CPU provides 244 bytes each of process-input and process-output image, with a default preset of 120 bytes. Up to 16 SFBs are available for high-level communication and system functions, and forcing is supported for commissioning and fault simulation.","metaTitle":"Siemens 6ES7416-2FN05-0AB0 S7-400 CPU, 25 mm wide, ATEX II 3","metaDescription":"Siemens 6ES7416-2FN05-0AB0 S7-400 CPU with CFC, FBD, LAD, SCL, STL, GRAPH, MPI, RS 485, cULus, ATEX II 3G Ex nA IIC T4 Gc.
