The Siemens SIMATIC S7-300 CPU 314C-2 PtP (6ES7314-6BH04-0AB0) is an advanced, high-performance compact central processing unit engineered to handle complex, mid-to-large scale industrial automation tasks. Distributed by OUKE, this all-in-one controller features a significantly expanded 192 KB working memory—offering a massive capacity increase over previous generations—allowing it to effortlessly store larger user programs, execute dense data blocks, and ensure reliable data retentivity.

It seamlessly integrates a Multi-Point Interface (MPI), onboard digital/analog I/Os, 4 high-speed counters (60 kHz), and a dedicated RS-422/485 serial point-to-point (PtP) interface. This allows direct serial device connectivity (such as barcode scanners, printers, and weighing scales) without requiring extra communication modules.

Comparison and Replacement

Compared with CPU 314C-2 DP: the PTP version is more focused on RS485 serial communication, while the DP version is better for PROFIBUS DP networks.
Compared with CPU 314C-2 PN/DP: PN/DP is more suitable for Ethernet-based and more advanced communication requirements.
Replacement suggestion: choose the PTP version for basic control and serial communication, or choose DP / PN/DP models for industrial network integration.
