The Siemens 6ES7317-2AK14-0AB0 is a powerful CPU module from the renowned SIMATIC S7-300 family. This controller is specifically engineered for applications requiring high processing speed and significant memory capacity. With its integrated MPI/DP and PROFIBUS DP interfaces, it offers exceptional connectivity for distributed automation tasks. Consequently, this CPU serves as the backbone for numerous manufacturing and process automation systems worldwide.
The SIMATIC CPU 317-2 DP comes equipped with 1,024 KB of integrated work memory, which is non-expandable but ample for complex control programs. For load memory, it requires a Micro Memory Card (MMC) that supports up to 8 MB, ensuring reliable data storage for at least ten years. In terms of processing speed, this unit is exceptionally fast, handling bit operations in just 0.025 µs, word operations in 0.03 µs, and floating-point arithmetic in 0.16 µs. Furthermore, it supports up to 2,048 total blocks, including DBs, FBs, and FCs, each with a maximum size of 64 KB.
This model features two integrated RS-485 interfaces. The first interface supports MPI and PROFIBUS DP protocols with a maximum transmission rate of 12 Mbps. It can serve as a DP master for up to 124 devices or as a DP slave. Meanwhile, the second interface is dedicated to PROFIBUS DP, also supporting master/slave configurations and isochronous mode with OB 61. Consequently, the CPU 317-2 DP 6ES7317-2AK14-0AB0 offers flexible routing, PG/OP communication, and S7 basic communication, making it suitable for complex network architectures.
The 6ES7317-2AK14-0AB0 supports a substantial I/O address area, with up to 8,192 bytes each for inputs and outputs. This includes a process image of 8,192 bytes for both, which is adjustable. For digital channels, it can handle up to 65,536 inputs and outputs, with 1,024 centrally. Similarly, for analog channels, it supports up to 4,096 inputs and outputs, with 256 centrally. This extensive capacity makes it a versatile choice for large-scale automation projects.
This CPU operates on a rated DC voltage of 24 V, with a permissible range of 19.2 V to 28.8 V. The typical current consumption is 870 mA, while in no-load operation it draws about 120 mA. The inrush current is typically 4 A, and the unit has a power loss of approximately 4.5 W. For mains buffering, it offers a stored energy time of 5 ms, with a minimum repeat rate of 1 second.
The module is compact, measuring 40 mm in width, 125 mm in height, and 130 mm in depth. It weighs approximately 360 grams, making it a lightweight yet robust component for any control cabinet.
Installing the Siemens 6ES7317-2AK14-0AB0 is straightforward. It mounts onto a standard S7-300 rail within a rack. The system supports up to three expansion units and a maximum of four racks, with each rack accommodating up to eight modules. Additionally, engineering requires STEP 7 software, such as V5.5 + SP1 or higher, ensuring compatibility with modern programming environments.
It is crucial to note that a Micro Memory Card is mandatory for operation, as this CPU lacks internal load memory. The MMC can be up to 8 MB and is used for storing the user program and data, ensuring battery-free, maintenance-free backup.

Q1: What is the maximum memory capacity for this CPU?
The 6ES7317-2AK14-0AB0 has 1 MB of integrated work memory, which cannot be expanded. For load memory, it supports an MMC up to 8 MB.
Q2: Can this CPU operate as a DP slave on both interfaces?
No, while the CPU 317-2 DP can be a DP slave, it cannot operate as a slave on both interfaces simultaneously. It supports master/slave configurations per interface.
Q3: What programming software is required?
Engineering requires STEP 7 V5.5 + SP1 or higher, or STEP 7 V5.2 + SP1 with HSP 202 for proper configuration.
Q4: How is the data retained during a power failure?
Data is backed up on the MMC without a battery, ensuring program and data integrity for at least ten years. The real-time clock also has a backup time of six weeks at 40°C.
Q5: Does this module support isochronous mode?
Yes, the second PROFIBUS DP interface supports isochronous mode with OB 61, making it suitable for high-precision motion control applications.
