Siemens 6ES7314-1AG14-0AB0 S7-300 CPU | Industrial Spare Part

The Siemens 6ES7314-1AG14-0AB0 CPU 314 is a standard modular controller for the SIMATIC S7-300 platform, designed for mid-range manufacturing automation and process control applications requiring modular I/O expansion.

Key Technical Specifications

• Manufacturer: Siemens
• Part Number: 6ES7314-1AG14-0AB0
• Product Series: SIMATIC S7-300
• CPU Model: CPU 314
• Work Memory: 128 KB integrated work memory (operation requires a SIMATIC Micro Memory Card / MMC for load memory and retentive data storage, supporting up to 8 MB MMC)
• Integrated I/O: None (standard modular CPU; external S7-300 signal modules are required for digital or analog I/O)
• Communication Interface: 1x MPI (RS-485) interface supporting programming (PG) and operator panel (OP/HMI) communication (up to 12 connections)
• Rack Expansion: Supports 1 central rack and up to 3 expansion racks (multi-tier configurations require IM 360/IM 361 interface modules; module capacity and slot assignments depend on system rack configuration)
• Engineering Software Requirements: STEP 7 V5.5 SP1 or higher; for STEP 7 V5.2 SP1 environments, verify and install hardware support package HSP 218 as required by Siemens documentation.

Applications and System Configuration

This controller is engineered for standalone machinery and centralized process applications requiring modular signal expansion without integrated distributed fieldbus ports. Because it does not feature onboard I/O, all digital, analog, and specialty functions are configured using external S7-300 signal and function modules across supported central and expansion tiers. Verify total module count, address allocation, rack configuration, and memory requirements prior to installation.
