Siemens SIMATIC S7-300 CPU 315-2 DP 6ES7315-2AG10-0AB0 – New & Original

Siemens SIMATIC S7-300 CPU 315-2 DP 6ES7315-2AG10-0AB0 | Reliable Automation Component

Field Application & Operational Analysis

From the perspective of a Site Reliability Engineer managing mission-critical production environments, the 6ES7315-2AG10-0AB0 stands as a cornerstone of system availability in medium-to-large-scale industrial automation. This CPU module delivers deterministic real-time control with an integrated PROFIBUS DP master interface, enabling seamless integration across distributed I/O networks — a decisive advantage when operational excellence cannot be compromised. Its role in process optimization extends from packaging lines to material handling systems, where sub-millisecond cycle times directly translate to throughput gains.

Engineered for durability in demanding industrial environments, the 6ES7315-2AG10-0AB0 operates reliably across a temperature range of 0°C to +60°C (horizontal mounting) and meets stringent EMC standards per EN 61000-6-2/4. Installation requires careful attention to DIN rail slot positioning (CPU slot 1), proper Micro Memory Card (MMC) insertion prior to power-up, and correct PROFIBUS DP termination resistor configuration at network endpoints. Failure to observe these steps is a leading cause of commissioning delays in the field.

As a legacy module approaching end-of-life status, maintaining a verified stock of the 6ES7315-2AG10-0AB0 as a critical spare part is a non-negotiable element of any robust maintenance strategy. Production lines dependent on SIMATIC S7-300 architecture face extended downtime risks if replacement units are not pre-positioned — a risk that far outweighs the cost of proactive inventory management.

Key Operational Features

High-Performance Processing: 32-bit RISC processor with 0.1-0.6 µs binary instruction execution for real-time control precision.
Integrated PROFIBUS DP Master: Supports up to 125 DP slaves at 12 Mbps — enabling large-scale distributed I/O modules without additional hardware.
128 KB Work Memory: Fully available for program and data, supporting complex automation logic without memory constraints.
Redundancy-Ready Architecture: Compatible with S7-300 redundancy configurations via IM 360/361 interface modules across up to 4 racks.
Battery-Backed Real-Time Clock: Ensures time-stamped diagnostics and retentive data integrity during power interruptions — critical for high-availability systems.
Multi-Protocol Communication: MPI/DP interface supports PG/OP connections, S7 routing, and global data exchange for system integration across heterogeneous networks.

Maintenance & Performance Benchmarks

The 6ES7315-2AG10-0AB0 is engineered to adapt across diverse industrial network architectures. In small-scale deployments, it functions as a standalone controller managing up to 31 expansion modules on a single rack. In larger installations, it serves as the central processing node in multi-rack configurations (up to 4 racks via IM 360/361), coordinating I/O modules across geographically distributed control panels.

Performance benchmarks confirm a typical instruction cycle of 0.3 ms per 1K instructions, with a diagnostics buffer retaining the last 100 of 256 entries — providing maintenance engineers with actionable fault history for root cause analysis. The module’s compatibility with STEP 7 V5.5+ and TIA Portal V13+ (with HSP) ensures continuity in environments where legacy programming infrastructure remains in active use. For process optimization initiatives, the isochronous DPV1 mode enables synchronized I/O sampling across the PROFIBUS network, reducing jitter in time-sensitive control loops.

Comprehensive Data Sheet

Every unit of the 6ES7315-2AG10-0AB0 is dispatched in Original Factory Packaging, preserving ESD protection and ensuring the module arrives in field-ready condition. For urgent maintenance scenarios, same-day dispatch is available on confirmed in-stock units — a critical capability when production downtime costs are measured in thousands per hour.

As a globally recognized EOL/Legacy module, sourcing the 6ES7315-2AG10-0AB0 through established industrial distributors with verified global supply chains is essential. Our worldwide express logistics network covers major industrial hubs across Asia, Europe, and the Americas, with full shipment tracking and customs documentation support. All units are subject to pre-shipment functional verification to guarantee operational integrity upon arrival.

Engineering Support & FAQ

Q1: What Micro Memory Card (MMC) is required for the 6ES7315-2AG10-0AB0?
A: The CPU requires an external MMC for load memory. Recommended options include the 6ES7953-8LF31-0AA0 (512 KB) or 6ES7953-8LG31-0AA0 (4 MB). The MMC must be inserted before powering on the CPU; failure to do so will result in a STOP state with SF LED active.

Q2: Which firmware versions are compatible with this CPU?
A: The 6ES7315-2AG10-0AB0 supports firmware up to V2.6. Programming is supported via STEP 7 V5.5 SP4 HF5 or later, and via TIA Portal V13 SP2 with the corresponding Hardware Support Package (HSP). Always verify HSP version compatibility before project migration.

Q3: How do I configure the PROFIBUS DP master interface during commissioning?
A: In STEP 7 HW Config, assign the CPU to Slot 1, then configure the DP master system under the MPI/DP port properties. Set the PROFIBUS address (default: 2), baud rate (up to 12 Mbps), and import GSD files for third-party DP slaves. Ensure bus termination resistors are active at both physical ends of the PROFIBUS segment.

Q4: What is the warranty coverage for this module?
A: All units supplied carry a 1-Year Warranty covering manufacturing defects and functional failures under normal operating conditions. Warranty claims are processed within 5 business days upon receipt of the defective unit, with advance replacement available for critical production environments upon request.

Q5: Can the 6ES7315-2AG10-0AB0 be used as a hot standby redundancy CPU?
A: This specific variant does not support H-system (hot standby) redundancy natively. For redundant CPU configurations within the S7-300 family, the 6ES7315-6FF04-0AB0 (CPU 315F-2 PN/DP) or S7-400H series should be evaluated. The 6ES7315-2AG10-0AB0 is best suited for standard (non-redundant) automation architectures.

Q6: How do I perform a CPU memory reset (MRES) on this module?
A: Turn the mode selector to STOP, then hold it in the MRES position for 3 seconds until the STOP LED flashes rapidly. Release and return to MRES within 3 seconds — the CPU will complete the memory reset cycle. This procedure clears all user program data and resets retentive memory; ensure a current program backup exists on the MMC before proceeding.
