The Siemens 6ES7416-2XN05-0AB0 is a powerful central processing unit from the SIMATIC S7-400 family. This CPU 416-2 model handles demanding automation tasks in mid-sized to large facilities. It provides 5.6 MB of integrated work memory, with 2.8 MB reserved for code and 2.8 MB for data. Its robust architecture ensures reliable operation under continuous industrial use.
The hardware functional status of this Siemens CPU 416-2 is 04. Engineering requires STEP 7 V5.3 SP2 or higher. The CPU relies on a battery-backed memory concept for secure data retention during power interruptions. Additionally, it supports Configuration in RUN (CiR), which minimizes downtime during system modifications. The basic synchronization time is 100 ms, plus 10 µs per I/O byte.
Memory and Processing Performance
The 6ES7416-2XN05-0AB0 offers substantial memory capacity for extensive programs. Its 5.6 MB work memory is non-expandable but sufficient for complex logic. The load memory accepts FEPROM and RAM expansion cards up to 64 Mbyte. Processing times are exceptionally rapid. For example, bit operations execute in just 30 ns. Similarly, word and fixed-point arithmetic also take 30 ns. Moreover, floating-point arithmetic completes in 90 ns. This CPU supports up to 10,000 DBs, 5,000 FBs, and 5,000 FCs, with each block sized up to 64 KB.
Counters, Timers, and Data Areas
The Siemens S7-400 CPU includes 2,048 S7 counters and 2,048 S7 timers, both with adjustable retentivity. It also supports unlimited IEC counters and timers via SFBs. The maximum retentive data area spans the entire work and load memory when battery-backed. The flag area is 16 KB, with retentivity preset for MB 0 to MB 15.
I/O Addressing and Interfaces
This controller supports an I/O address area of 16 KB for inputs and 16 KB for outputs. Its process image is adjustable to 16 KB for each, with a default of 512 bytes. For digital channels, it handles up to 131,072 inputs and outputs centrally. For analog channels, it manages 8,192 inputs and outputs centrally.
The Siemens 6ES7416-2XN05-0AB0 includes two RS 485 interfaces. The first is a combined MPI/PROFIBUS DP port, and the second is a dedicated PROFIBUS DP interface. The MPI/DP port operates at up to 12 Mbit/s. This CPU supports PG/OP communication, S7 routing, global data, and S7 basic communication. It also functions as both a client and server for full S7 communication.
Dimensions and Weight
The 6ES7416-2XN05-0AB0 measures 25 mm in width, 290 mm in height, and 219 mm in depth. It weighs approximately 0.86 kg. Its slim profile allows efficient use of rack space within the S7-400 system.
Power Consumption and Configuration
This module draws a typical current of 0.9 A from the 5 V DC backplane bus, with a maximum of 1.1 A. It also draws up to 300 mA from the 24 V DC backplane bus for its DP interfaces. Typical power loss is 4.5 W, with a maximum of 5 W. The Siemens CPU 416-2 supports up to 21 expansion units, enabling extensive system scalability. It accommodates up to 6 interface modules for remote racks and supports multicomputing mode with up to 4 CPUs.
Please note that the 6ES7416-2XN05-0AB0 is a discontinued product. Siemens officially terminated this item effective December 1, 2016. The recommended successor is the 6ES7416-2XP07-0AB0, which features 8 MB of work memory and enhanced capabilities. This listing is for the original model, suitable as a replacement part or for expanding existing systems.
Start by inserting the CPU into a free slot on the S7-400 rack. It occupies just one slot. For multicomputing setups, verify compatibility with other CPUs. Connect the battery to enable data retention. Use the MPI/DP interface for programming and HMI communication. The second PROFIBUS DP interface connects to distributed I/O devices. Configure the system using STEP 7 V5.3 SP2 or higher.
