6ES7315-2AH14-0AB0 Siemens Simatic S7-300 CPU 315-2DP Central Processing Unit

Product parameters

Power supply voltage: DC 19.2-28.8V

Input current: Rated value 850mA, typical no-load value 150mA, typical on-current value 3.5A

Power loss: Typical value 4.5W

Working memory: 256KB, non-expandable

Processing time: Bit operations approximately 50ns, floating-point operations 0.45μs

Communication interfaces: 1 MPI interface, 1 PROFIBUS DP interface

Number of expandable modules: Up to 32 modules (4-row structure)

Function

Communication function: Integrated MPI interface, capable of establishing up to 16 connections, supporting communication with programming devices, PCS, etc. The PROFIBUS DP master/slave interface can establish a distributed automation system and supports the PROFIBUS DP V1 standard.

Protection function: User programs can be password-protected to prevent illegal access. When the power is interrupted, the CPU automatically writes all data (up to 128KB) to the MMC card, achieving maintenance-free data backup.

Diagnostic function: The diagnostic buffer can store the last 500 error and interrupt events, among which 100 events can be permanently retained. The LED can indicate hardware, programming, time, I/O and other errors and operational status.

Parameterizable feature: The configuration, attributes and CPU responses of S7 can be parameterized using STEP 7, such as defining station addresses, setting maximum cycle times, load limits, etc.

Application scenarios

Manufacturing industry: For instance, in automotive welding production lines, multiple servo motors are coordinated through DP networks to achieve high-precision positioning control.

Process control: In the SCADA system of a water plant, its isochronous synchronization mode is utilized to ensure the millisecond-level linkage between flow meters and valves, achieving precise control of the water treatment process.

Energy management: It can be used to monitor and manage the energy consumption of industrial enterprises or commercial buildings, such as the measurement, analysis and optimized control of electricity, water, gas, etc.

Building automation: It is used for monitoring equipment in buildings, such as elevator control, air conditioning system control, lighting system control, etc., to achieve intelligent management and energy-saving operation of building equipment.
