Product details

CPU 314C-2 PN/DP – what the key specs mean

The 6ES7314-6BG03-0AB0 is a SIMATIC S7-300 CPU 314C-2 PN/DP with integrated 8-channel function module (FM 8) for fast counting, frequency measurement, and positioning. It supports CFC for graphical configuration of logic. Input capacity reaches 253 digital inputs, output capacity 250 digital outputs, realized via CP modules on the rack. The I²t rating of 0.7 A²·s limits short-circuit energy on the output module. Programming languages include LAD, FBD, STL, SCL, GRAPH, and HiGraph, with STEP 7 V5.3 SP2 (HW update required).

Occupies a single slot on S7-300 rack; dimensions 120×125×130 mm. RS 485 (X.27) supports PROFIBUS and point-to-point via ASCII; MPI not supported. Supports 4 CP modules for LAN, 10 CP for PtP communication. Routing not available on this CPU. PROFIsafe not supported.

Frequently asked questions

What does FM 8 mean on this CPU?

FM 8 indicates 8 integrated fast counter channels (function module) for counting, frequency measurement, or positioning tasks without a separate module.

Does the 6ES7314-6BG03-0AB0 support CFC?

Yes, CFC (Continuous Function Chart) is supported for graphical logic configuration.

What programming languages are available?

Ladder (LAD), Function Block Diagram (FBD), Statement List (STL), Structured Control Language (SCL), GRAPH (sequential control), and HiGraph (state machine) are supported.
