Hollysys LX-CU100/CU300 - Net/IO-Control - Rugged Expandable Industrial PLC
The Hollysys LX-CU100 / LX-CU300 series represents the company's third-generation compact programmable logic controllers, engineered around a multi-core domestic-chip architecture with an integrated 32-point high-speed I/O block to eliminate external I/O modules for common tasks. Key parameters include an ultra-narrow width of approx. 70 mm, dual expansion card slots, and native Ethernet connectivity supporting Modbus TCP and multiple industrial protocols. The CU100 drives up to 12 pulse-controlled axes with PLCopen motion algorithms, while the CU300 scales further with 32-axis EtherCAT bus control plus 6 pulse axes and up to 96 EtherCAT slaves, making them ideal for packaging machines, textile equipment, 3C/electronics assembly lines, and compact OEM machinery.
Both controllers run on the Intelligent AutoThink (iAT) platform—a 5th-generation, IEC 61131-3-compliant environment that also supports C/C++ and G-code programming for maximum flexibility. Core advantages are space/cost savings (onboard I/O + right-side expansion of up to 16 I/O modules on CU100), deterministic motion performance via EtherCAT on the CU300, and domestically sourced silicon for supply-chain autonomy. With protocol-rich networking, hot-swappable expansion options, and a rugged design ethos suited to panel-tight installations, the series delivers a compelling domestic alternative for high-speed, motion-centric compact automation where cabinet real estate and multi-axis coordination matter.
