Features:
- Central Processing Unit Bridging Control Logic and Distributed I/O Networks
- Integrates Multi-Protocol Communication with High-Speed Data Processing
- Functions in Coordination with SIMATIC S7-300 Modules and PROFINET/PROFIBUS Devices
The SIEMENS 6ES7318-3EL01-0AB0 serves as the Central Processing Unit in a SIMATIC S7-300 rack, providing reliable execution of control programs for all modules within the system. It continuously processes complex automation tasks using its 2 MB work memory and distributes control commands through the rack backplane to support steady-state operation of all signal modules and function modules. Seamless protocol integration is standard with the 6ES7318-3EL01-0AB0, and its three independent communication interfaces enable simultaneous operation across MPI/DP, PROFIBUS DP, and PROFINET networks without interruption.
The 6ES7318-3EL01-0AB0 provides essential processing functions common to the entire rack, and is a critical component of the control path, directly affecting the proper, normal operation of the overall automation system. One 6ES7318-3EL01-0AB0 CPU is required per rack as the central controller. The 6ES7318-3EL01-0AB0 occupies a standard slot in the rack and is always located in the designated CPU position.
For expanded communication applications, the 6ES7318-3EL01-0AB0 leverages its 2nd interface as a DP master or slave and its 3rd interface as a PROFINET controller with integrated switch functionality. In addition to standard single-network operation, the multi-interface configuration also performs simultaneous protocol handling. The 6ES7318-3EL01-0AB0 dual-protocol configuration executes data exchange using the internal circuitry specified in the CPU communication options.
The 6ES7318-3EL01-0AB0 SIEMENS Central Processing Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
