PRODUCT DESCRIPTION
Ninety-six-kilobyte execution memory for modular S7-300 control
Siemens 6ES7314-1AG13-0AB0 is a SIMATIC S7-300 CPU 314 with 96 KB of integrated working memory and an MPI interface. It uses a SIMATIC Micro Memory Card for load storage and supports maintenance-free, battery-free retention of program and data.
The CPU accommodates compatible modules across four racks and offers a buffered hardware clock, 256 counters and 256 timers. Its MPI communication resource provides twelve connections, while the diagnostic buffer and variable-monitoring functions support examination of program execution and station operating conditions.

Manuals & support
SIMATIC S7-300 CPU 314
Modular processing with separately defined retention resources
The AG13 executes the program and data within 96 KB of working memory, while the MMC supplies load storage. The documented 64 KB retention ceiling remains a distinct constraint for retained data.
Compatible modules provide field I/O and other station functions across the supported four-rack arrangement. The configured addresses and process image should be checked against the CPU resource limits.
The integrated MPI function supports programming and the documented communications services through twelve available connections. The buffered clock and diagnostic functions complement operation without implying built-in field channels or Ethernet.
Features:
- 96 KB work-memory resource
- Separate retention budget
- MPI connection allocation
The Siemens 6ES7314-1AG13-0AB0 requires the documented hardware configuration, installation conditions and interface arrangement to be verified before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
Identify the full AG13 code and the offered unit's firmware before selecting a replacement. The reference data sheet records V2.6, but it is not proof of the installed version of a particular stock unit.
Preserve the existing STEP 7 project and MMC contents. Compare memory usage, retained data, rack expansion, addresses and communication allocations before transferring an existing project.
Check the removable power plug and DC polarity, then follow the applicable installation manual for controlled recommissioning. Current availability, lifecycle dates and automatic substitution by another CPU 314 suffix are not established by the historical data sheet.
Features:
- Exact AG13 identification
- Memory and retention review
- Controlled project transfer
The Siemens 6ES7314-1AG13-0AB0 requires replacement verification based on its complete order number, installed hardware, signal configuration and project documentation.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about 6ES7314-1AG13-0AB0
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
Are all 96 KB of work memory retentive?
No. Siemens lists 96 KB of working memory but specifies a total retentive-data limit of 64 KB. Working memory and the retained-data budget must therefore be checked separately. -
Does AG13 include Ethernet or a DP interface?
The exact data sheet lists MPI functionality and expressly excludes integrated Ethernet, PROFIBUS DP master and PROFIBUS DP slave functions. Any communication-processor solution requires a separate configuration check. -
Can field signals connect directly to this CPU?
No integrated digital or analog I/O channels are listed. Compatible S7-300 modules provide field I/O within the CPU's permitted rack arrangement and address resources. -
Which engineering software is specified?
The data sheet specifies STEP 7 V5.2 SP1 or higher with a hardware update. Match that requirement to the actual firmware and hardware support used in the saved engineering project. -
What is required before initial energization?
The applicable installation manual calls for the correct MMC and STOP selector position before initial power-on. Verify the documented removable DC plug, L+ and M polarity, and the completed safety checks first. -
Is the listed 280 g a shipping weight?
No. Approximately 280 g is the CPU's own weight, and 40 x 125 x 130 mm is its own size. Neither value establishes the packed dimensions or gross shipping weight.
