The CompactLogix platform brings together the benefits of the Logix platform — common programming environment, common networks, common control engine — in a small footprint with high performance. Combined with Compact I/O, the CompactLogix platform is perfect for tackling smaller, machine-level control applications, with or without simple motion, with unprecedented power and scalability. CompactLogix is ideal for systems that require standalone and system-connected control over EtherNet/IP, ControlNet, or DeviceNet networks.
