        Siemens Simatic S7-300

        SIMATIC S7-300 is a DIN-rail PLC you build yourself: click in a power supply, CPU, and any mix of digital, analog, function or communication modules—snap the bus connector and download; the rail-free design saves panel space, scales from tens to thousands of I/O, integrates PROFIBUS/PROFINET drives, safety or process loops, and supports hot-swap for maintenance without stopping the line.
