The Siemens 6ES7416-3XR05-0AB0 is a premium central processing unit from the SIMATIC S7-400 family. This CPU 416-3 model is designed for the most demanding automation applications in large industrial plants. It provides 5.6 MB of integrated work memory, split evenly between code and data storage. The module also includes three communication interfaces for maximum connectivity.
The hardware functional status of this Siemens CPU 416-3 supports advanced system integration. Engineering requires STEP 7 V5.3 SP2 or higher. The CPU uses a battery-backed memory concept for reliable data retention during power outages. Furthermore, it supports Configuration in RUN (CiR), allowing system modifications without stopping production. The basic synchronization time is 100 ms, with 10 µs added per I/O byte.
Please be aware that the 6ES7416-3XR05-0AB0 is a discontinued product. Siemens officially cancelled this item effective December 1, 2016. The recommended replacement is the 6ES7416-3XP07-0AB0, which offers enhanced memory and performance. This listing is for the original model, suitable as a replacement part or for maintaining existing S7-400 systems.
Memory and Processing Performance
The 6ES7416-3XR05-0AB0 provides substantial memory capacity for extensive automation programs. Its 5.6 MB work memory is non-expandable but sufficient for large-scale logic. The load memory accepts FEPROM and RAM expansion cards up to 64 Mbyte. Processing times are exceptionally fast. For instance, bit operations execute in just 30 ns. Similarly, word and fixed-point arithmetic also complete in 30 ns. Moreover, floating-point arithmetic finishes 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 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 Communication 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 6ES7416-3XR05-0AB0 includes three RS 485 interfaces. The first is a combined MPI/PROFIBUS DP port, the second is a PROFIBUS DP interface, and the third is an additional PROFIBUS DP or IF module port. The MPI/DP port operates at up to 12 Mbit/s. This CPU supports PG/OP communication, S7 routing, global data, S7 basic communication, and full S7 communication as both client and server.
Dimensions and Weight
The 6ES7416-3XR05-0AB0 measures 303 mm in length, 233 mm in width, and 63 mm in height according to its packaging dimensions. Its net weight is approximately 1.001 kg, with a gross weight of 1.10 kg.
Power Consumption and Configuration
This module draws a typical current of 1.0 A from the 5 V DC backplane bus. Typical power loss is 5.5 W. The Siemens CPU 416-3 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.
Environmental Compliance
This product complies with the RoHS directive since November 21, 2006. It contains lead (CAS-No. 7439-92-1) at a concentration above 0.1% (w/w) as per REACH Article 33. The unit is not classified as dangerous goods for shipping.
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 and third PROFIBUS DP interfaces connect to distributed I/O devices and additional communication modules. Configure the system using STEP 7 V5.3 SP2 or higher.
