The Schneider Electric TM171OFM22R is a 22-inch Touchscreen Logic Controller from the Modicon TM171 series. This all-in-one unit combines a programmable logic controller (PLC), a large-scale Human-Machine Interface (HMI), and embedded local I/O into a single, panel-mounted device. The "OFM" suffix indicates it belongs to the Optimized/Advanced line with a high-performance display and embedded runtime license. Designed for applications requiring extensive visualization and local control, it is ideal for use as a central operator station on large machines or production lines.
