Functions

Central control

Executes the S7-300 user program with 256 KB integrated work memory.

Distributed I/O

The integrated DP interface operates as PROFIBUS DP master or device.

Maintenance-free backup

Program and data backup is provided through the required Micro Memory Card without a battery.

Interfaces

MPI interface

Provides the integrated multipoint interface for programming and S7 communication.

PROFIBUS DP

The second interface supports DP master and DP device operation.

Processing

Typical execution time is 0.05 µs for bit operations, 0.09 µs for word operations, and 0.12 µs for fixed-point arithmetic.

Installation

Power connection

Use a regulated 24 V DC supply within 19.2 to 28.8 V; Siemens recommends suitable external line protection.

Rack installation

Mount the 40 mm wide CPU in the S7-300 rack and observe the 125 x 130 mm height and depth.

Memory card

Install a compatible Micro Memory Card; the official maximum plug-in load memory is 8 MB.

Compatibility

Exact CPU variant

Confirm CPU 315-2 DP, hardware status 01, firmware V3.3, and complete suffix 2AH14-0AB0.

Software match

Verify the STEP 7 version, hardware catalog entry, MMC contents, and existing rack configuration before replacement.

Network match

Confirm MPI and PROFIBUS DP addressing, baud rate, master/device role, and connected distributed stations.

FAQ

Q1. How can the quoted CPU be verified as 6ES7315-2AH14-0AB0?

Require a legible Siemens label showing the complete order number, CPU 315-2 DP designation, hardware status, and firmware identification. The 2AH14-0AB0 suffix must match.

Q2. How can condition be distinguished for this S7-300 CPU?

Request timestamped photos of the housing, front flap, MPI/DP connectors, power terminals, rear bus connector area, MMC slot, and packaging. Connector wear or repaired plastic should be disclosed.

Q3. How should the supplier be validated?

Check legal company registration, address, corporate payment account, quotation traceability, invoice capability, and consistent model-specific evidence for 6ES7315-2AH14-0AB0.

Q4. Which engineering checks are required before ordering?

Verify 24 V DC supply, 256 KB work memory, MPI and PROFIBUS DP roles, STEP 7 compatibility, rack addressing, and the required Micro Memory Card up to 8 MB.

Q5. What evidence should be requested before payment?

Ask for full nameplate, connector, terminal, front, rear, MMC-slot, and packaging photos plus a continuous video of the same serial-marked unit.

Q6. Can another CPU 315 suffix replace 6ES7315-2AH14-0AB0?

Do not assume it can. Work memory, firmware, interface type, hardware catalog support, and project configuration can differ. Replacement requires engineering approval of the complete ordering code.
