Siemens 6ES7414-2XL07-0AB0 SIMATIC S7-400 CPU
The Siemens 6ES7414-2XL07-0AB0 is a SIMATIC S7-400 CPU 414-2, a high-performance modular CPU built for large-scale, centralized industrial process automation. Unlike newer Siemens CPU families, this model communicates through two PROFIBUS-based interfaces rather than PROFINET, making it well suited to plants that rely on classic fieldbus networks. As a fully modular controller, it mounts on a universal rack (UR) alongside a dedicated power supply module and a wide range of digital, analog, and communication I/O modules.

Description
The Siemens SIMATIC S7-400 CPU 414-2 offers 2 MB of total work memory, split into 1 MB for program code and 1 MB for data, giving it strong capacity for large, centralized control programs. It runs on power supplied through the system power supply module rather than a direct DC input, and includes two RS 485-based interfaces — the first a combined MPI/PROFIBUS DP port, and the second a dedicated PROFIBUS DP port — allowing it to manage two separate fieldbus networks at once. Program and data can be backed up with a battery for full retention, or expanded using FEPROM or RAM memory cards.
This CPU is programmed using STEP 7 (V5.4 or higher) and supports LAD, FBD, STL, SCL, CFC, GRAPH, and HiGraph programming languages. It supports multicomputing with up to 4 CPUs in a single rack, extensive PROFIBUS DP master and slave functionality, and configuration changes while the system is running (CiR). With support for up to 21 expansion units and 63 connectable operator panels, it’s built for large, centralized automation systems with extensive I/O and operator interface requirements.
