Description
The Siemens SIMATIC S7-300 series Compact CPUs, models 6ES7314-6BH04-0AB0 (CPU 314C-2 PN/DP) and 6ES7314-6CH04-0AB0 (CPU 314C-2 PtP), are all-in-one programmable controllers designed for medium-scale automation tasks. These robust units integrate a CPU, digital/analog I/O, and high-speed counters into a single module, eliminating the need for separate I/O cards in many applications. The 6BH04 features built-in PROFINET and PROFIBUS DP communication, while the 6CH04 features PROFIBUS DP and serial point-to-point (PtP) communication. With IP20 protection and a wide operating temperature range, they are ideal for stand-alone machine control, process automation, and distributed I/O systems.
