Product details

CPU 313C with 8 FM blocks and 248 I/O

The Siemens 6ES7313-6BG04-0AB0 is a CPU 313C for the S7-300 rack, rated for 0 °C to 60 °C ambient — suited for unheated control cabinets in production halls where the panel stays above freezing. It supports 8 FM (function module) blocks, which means the CPU can handle up to 8 technology or communication function modules in the same rack without a separate external processor. Digital I/O capacity reaches 248 inputs and 248 outputs, with forcing supported for commissioning and fault-finding. The backplane is isolated, so the CPU and I/O modules share a common reference but the field-side circuits are separated from the rack logic.

Programming and communication constraints

This CPU runs STEP 7 V5.5 + SP1 or higher (or V5.3 + SP2 with HSP 203) — it does not support TIA Portal natively. Programming languages include LAD, FBD, STL, SCL, GRAPH, HiGraph, and CFC, covering both IEC 61131-3 and Siemens-specific high-level blocks. Point-to-point communication uses RS 485 (RS 422/485 X.27) with ASCII, 3964(R), and RK 512 protocols. MPI is not supported, so the CPU cannot participate in an MPI network — use the integrated PtP or add a CP for PROFIBUS or Ethernet. PROFIsafe is not supported, so this CPU is not suitable for fail-safe safety applications.

Rack layout and memory sizing

The CPU occupies one slot in an 8-module rack (overall 8 modules including the CPU). Dimensions are 80 mm wide, 125 mm high, 130 mm deep — standard S7-300 form factor that fits the 80 mm DIN-rail footprint. The I2t rating of 0.7 A²·s limits the inrush current from the backplane bus; ensure the power supply can handle the module load without exceeding this threshold. Retentive data is configurable from 10 to 499 DBs, but must be restarted at each restart — the CPU does not retain the last retentive state across a power cycle without a battery backup or an MMC. The retentive variables cover inputs, outputs, memory bits, DBs, timers, and counters.

The 6ES7313-6BG04-0AB0 is an active-production CPU within the S7-300 family. No successor or phase-out notice has been issued.

Frequently asked questions

What is the work memory of 6ES7313-6BG04-0AB0?

The work memory size is not listed in the available specifications. The CPU supports up to 248 digital inputs and outputs, with retentive data configurable from 10 to 499 DBs. For exact memory sizing, refer to the Siemens configuration manual for the CPU 313C.

What is the difference between 6ES7313-6BG04-0AB0 and 6ES7313-6BG03-0AB0?

The 6ES7313-6BG04-0AB0 is the later revision of the CPU 313C, with updated firmware and support for STEP 7 V5.5 + SP1. The earlier 6ES7313-6BG03-0AB0 requires STEP 7 V5.3 or earlier. Both share the same 80x125x130 mm form factor, 8-module rack limit, and 248 I/O capacity, but the -0AB0 revision adds CFC and HiGraph support.
