Product details

CPU Capabilities and Programming

The Siemens 6ES7318-3EL00-0AB0 is a SIMATIC S7-300 SFB (Safety Fault-Proof) CPU with FM 8, supporting CFC, FBD, LAD, SCL, STL, GRAPH, and HiGraph programming languages. It provides 244 bytes each of process input and output image, with a total of 32 blocks overall. Integrated PROFINET interface enables UDP and TCP/IP communication via loadable function blocks. RS 485 is also present for serial links. No MPI or DPV1 support on this CPU. The CPU supports routing and can act as both PROFINET client and server. PROFIsafe is not supported, so this is not a safety-rated CPU for fail-safe applications.

Physical Dimensions and Environment

Dimensions are 120 mm wide, 125 mm high, and 130 mm deep. Operating temperature range is 0 °C to 60 °C. The I2t rating is 1.2 A²·s, relevant for short-circuit withstand coordination in the panel.
