Siemens 6ES7314-1AG13-0AB0 CPU 314 Controller

Siemens 6ES7314-1AG13-0AB0 is a SIMATIC S7-300 CPU314 central processing unit designed for legacy automation projects requiring compact, reliable control. This CPU314 module features an MPI interface for PLC communications and an integrated 24 V DC power supply, simplifying wiring on DIN-rail installations. It provides 96 KB of working memory for program and data handling and requires a Micro Memory Card (MMC) for program storage and data logging. As a spare part for the S7-300 family, it serves as a replacement option when maintaining or restoring older production lines that rely on CPU314 performance. The part number 6ES7314-1AG13-0AB0 identifies a CPU314 with these core capabilities, consolidating processing, communication, and storage needs in a single module. This controller maintains compatibility with existing S7-300 configurations and supports the MPI networking that links the CPU with I/O modules and programming devices.
