Siemens 6ES7318-3EL01-0AB0 Programmable Logic Controller CPU Module

Siemens 6ES7318-3EL01-0AB0 is a SIMATIC S7-300 CPU 319-3 PN/DP module with 2 MB of working memory, three network interfaces (MPI/DP at 12 Mbit/s, DP master/slave, and Ethernet PROFINET with a built‑in 2‑port switch), and a Micro Memory Card requirement. This CPU serves as the central processing unit for SIMATIC S7-300 automation projects, enabling distributed control across PLC networks via MPI/DP, DP, and PROFINET, and it is programmable with STEP 7 V5.5 or higher. Electrical specs specify 24 V DC supply, rated current around 1.25 A, typical power loss about 14 W, integrated memory 2048 Kibyte, and MMC data retention up to 8 MB. Designed for machine and process control tasks requiring multi-network connectivity, it complements legacy S7-300 installations while enabling PROFINET-based communication with other Siemens devices.
