It carries ATEX II 3G Ex nA IIC T4 Gc certification, meaning it is approved for installation in Zone 2 gas atmospheres — a panel builder placing this CPU in a potentially explosive environment has the nameplate to satisfy the ATEX 2014/34/EU directive without an external purge system. The CPU offers 244 bytes each of process input and output image, 16 counters with a preset of 120, and the FM function is limited by the number of slots and connections — a maintenance technician sizing a replacement should verify the existing rack configuration against that constraint before committing the swap. Communication interfaces include RS 485 and routing with the interface active; the unit supports up to 4 CP 443-1 modules in the central controller, but mixed operation of different CP 443-1 types in PROFINET IO mode is not allowed — a field service tech swapping a failed CP must match the exact type already installed. ## System function call limits — the numbers that matter for integration SFB 52 (RDREC) and SFB 53 (WRREC) each allow 8 calls per interface, with a total cap of 32 across all external interfaces — a controls integrator mapping multiple PROFIBUS or PROFINET devices must budget those calls so no single interface or the aggregate exceeds the limit. SFC 59 and SFC 58 each allow 8 calls per interface; SFC 51 (RDSYSST) also allows 8 calls; SFC 103 is limited to 1 per interface — these are hard firmware limits, not a recommendation, so a programmer writing the startup sequence should count them against the interface budget. For point-to-point communication, CP 440 is limited by the number of slots, while CP 441 is limited by the number of connections — a panel OEM planning serial links should choose the CP type that matches the available slot count versus the required connection count. ## Compliance and approvals — what the nameplate carries The CPU carries CE mark and cULus approval, so it is accepted in European and North American markets without additional certification effort — a quality doc control specialist can file the CE declaration and cULus listing as part of the panel's compliance package. ATEX II 3G Ex nA IIC T4 Gc certification covers Zone 2 gas groups IIC with a T4 temperature class — a functional safety engineer verifying the zone classification should confirm the T4 rating (135 °C max surface temperature) is adequate for the installed gas group. The unit supports STEP 7 programming and GSD file generation for PROFIBUS DP slave integration — a sourcing buyer can confirm the GSD file is available at the Siemens support portal for network configuration. ## Physical fit — mounting and dimensions The CPU measures 50 mm wide, 290 mm high, and 219 mm deep — a panel OEM laying out the S7-400 rack should allocate that width in the 19-inch subrack, leaving clearance above and below for the forced-air cooling that the 414-3 typically requires in a sealed enclosure. Operating temperature range is 0 °C to 60 °C — a field service tech installing the CPU in a non-conditioned cabinet should verify the ambient stays within that band, especially if the cabinet is near a heat source like a drive or transformer.","metaTitle":"Siemens 6ES7414-3XM07-0AB0 S7-400 CPU, CFC, ATEX Zone 2","metaDescription":"Siemens S7-400 CPU 414-3 PN/DP with CFC, FBD, LAD, SCL, STL, GRAPH support.
