technical parameters

Processors and Performance

• processor : Integrated high-performance processor, instruction execution speed.
• bit operation execution time : a typical value of 0.08 μs/instruction, which can quickly process logical operations and meet control tasks with high real-time requirements.
• Floating-point operation execution time : The typical value is 0.3 μs/instruction, suitable for complex mathematical calculations and control algorithms.

• working memory : Integrated 512KB random access memory (RAM), used to store programs and running data, to ensure the rapid execution of programs and timely processing of data.
• Load Memory : A memory card with a maximum support of 2MB (optional) is used to store user programs, data blocks, and system data to facilitate the storage and backup of programs.

interface

• MPI interface : Integrated multi-point interface (MPI) with a communication rate of 187.5kbps, which can be used to communicate with programming equipment, human-machine interface (HMI) or other Siemens equipment to realize functions such as program downloading, monitoring and debugging.
• PROFIBUS-DP master/slave interface : supports PROFIBUS-DP communication protocols, and the communication rate can reach up to 12Mbps. It can be used as a master station to connect distributed I/O devices, such as ET200 series modules, and can also be used as a slave station to communicate with other master stations to build a distributed automation control system.
• PROFINET interface : Integrated PROFINET interface, communication rate of 10/100Mbps, support TCP/IP, ISO-on-TCP and PROFINETIO communication protocols. It can be used to connect industrial Ethernet equipment, realize high-speed data exchange and remote monitoring, and facilitate networking and integration with other automation equipment.

Power and Power Consumption

• Supply voltage :24VDC
• Power consumption : The typical value is 12W. The relatively low power consumption helps reduce energy consumption and heat dissipation requirements.

Digital Input/Output

• Number of input points : can be extended up to 1024 points
• Digital output points : can be extended up to 1024 points

analog input/output

• Analog input channels : Expandable up to 128 channels
• Analog output channels : Expandable up to 128 channels

work environment

• Operating temperature range :0°C to 60°C
• Storage temperature range :-25°C to 85°C
• Relative humidity :5% to 95%, no condensation
• Pollution level :2

Plain language sourcing guide for 6ES7315-2EH14-0AB0 Siemens S7-300 High-Performance CPU Module

Start with the full model name. Check the brand name. Check the part number. Check the code on the old unit. These small checks help you avoid a wrong order.

Take one clear photo of the front label. Take one photo of the side label. If the part has a cable, plug, port, seal, coil, or screen, take a photo of that area too.

Tell us the quantity you need. Tell us your country. Tell us the date when the plant needs the part. We can then check stock, lead time, safe packing, and the best shipping plan.

If the exact model is no longer made, do not guess. Send the old model and the use case. LEHIY can compare close options and explain which choice is safer for repair work.

Use simple order notes. Write the model in one line. Write the quantity in one line. Write the delivery country in one line. This helps our team reply faster.

Check the old part before removal. Look at the label. Look at the connector. Look at the mounting size. Look at the voltage or pressure rating if it is shown.

Do not rely on a short nickname for a part. Many industrial items have close versions. A small suffix can change the plug, output, range, or software setting.

Ask for a stock check if the plant is stopped. Ask for a lead time if the order is planned. Ask for packing photos if the part is fragile or heavy.

For a replacement order, tell us what failed. Tell us where the part is used. Tell us if an equal model is acceptable. This makes the first answer more useful.

For repeat orders, send the last invoice, old label, or old packing photo. The same reference can help us match the correct product again.

For urgent service, keep the message simple. One model, one quantity, one photo, and one delivery target are enough for a fast first check.
