6ES7416-2XN05-0AB0 SIMATIC S7-400 CPU 416-2 DP. 5.6 MB integrated work memory, MPI/DP port + PROFIBUS DP port, up to 32 MB load mem (CF card), for mid-to-high complexity process & plant automation.
Product Overview
6ES7416-2XN05-0AB0 is a high-performance central processing unit (CPU 416-2 DP) from the SIMATIC S7-400 series, designed for medium to large-scale automation tasks in process industries, power plants, and complex machine lines. It features 5.6 MB integrated work memory, dual communication interfaces (MPI/PROFIBUS DP master/slave on Port 1, PROFIBUS DP master/slave on Port 2), and supports up to 32 MB load memory via a removable Compact Flash (MC) card. The CPU executes boolean operations in ~0.04 µs and supports extensive I/O expansion via S7-400 signal/modules and distributed I/O (ET 200M/ET 200S/ET 200pro over PROFIBUS DP or Industrial Ethernet with CP).
1 × MPI/PROFIBUS DP (Port X1 — configurable as MPI up to 12 Mbps or DP Master/Slave) 1 × PROFIBUS DP (Port X2 — DP Master/Slave, max. 12 Mbps)
Max. DP Slaves (per Port)
124 DP Slaves (Master Mode)
Integrated MPI Address
Default 2 (settable 0–126) — for PG/OP/HMI connection
Max. Distributed I/O (DP)
Limited by DP slave count & bus load — typical large-plant capacity
Max. Central I/O (S7-400 Rack)
Up to 4096 DI + 4096 DO (address range), 2048 AI + 2048 AO (depending on rack/PS capacity)
Supported Protocols
MPI, PROFIBUS DP-V0/V1, S7 Communication (PG/OP/HMI), System Redundancy (with 2x CPUs + sync modules)
Expandability
Up to 4 x UR1/UR2/CR3 racks with IM460/461 or IM470/471 (distributed I/O via DP preferred)
Operating Temperature
0 … +60 °C (Horizontal mounting in cabinet)
Backup Battery
S7-400 PS with buffering or external SITOP — work memory retentive with backup; clock buffered > 6 weeks typical
Key Features
Large Program Capacity: 5.6 MB work memory + up to 32 MB load memory (CF card) — handles extensive process logic, data logging, recipe management, and large symbol tables.
Dual PROFIBUS Ports: Native MPI/DP + dedicated PROFIBUS DP port allow segregation of engineering/PG traffic from field bus — no extra CP needed for two DP segments.
High-Speed Execution: Sub-0.1 µs boolean instruction time — suitable for complex closed-loop, math-intensive, or multi-axis coordination logic.
Redundancy Ready: Compatible with S7-400H redundant configuration when paired with a second CPU 416-2, sync modules (6ES7960-…), and redundant PS/IM — achieves SIL 3 / AK 6 category per IEC 61508 / IEC 62443.
Applications
Process Industries (Chemical, Pharma, Pulp & Paper): Large-scale batch/continuous control with hundreds of analog loops and extensive alarm/recipe handling.
Power Generation & Water Treatment: Unit/plant-level control coordinating multiple subsystems (BOP, CW, fuel handling, SCADA interface).
High-End Machine Lines: Multi-section web lines, press lines, or test stands with >1000 I/O points and tight timing requirements.
SCADA / MES Front-End: Acting as data concentrator and control engine for multiple subordinate PLCs/RTUs over PROFIBUS or Industrial Ethernet (with CP343-1/CP443-1).
Note: The Micro Memory Card (MMC/CF card — 6ES7952-1…-0AA0) with STEP 7 project, HW Config, and load memory must be ordered separately. For redundant H-system, two identical CPUs, sync fiber modules (6ES7960-1…), and a redundant power supply configuration are required. The CPU 416-2XN05-0AB0 is the V5.x firmware variant — ensure your STEP 7 version (V5.5 or newer recommended) supports it. For newer S7-400 CPUs with even larger memory, see CPU 417-4 (6ES7417-4XT05-0AB0).
