PRO, MAX Series PLC
Overview
The Samkoon PRO and MAX Series are high-performance, cabinet-optimized bus-type PLCs engineered for high-end multi-axis motion control, robotic cell coordination, and complex CNC applications. Powered by a deterministic real-time engine and native EtherCAT master stack, the controllers deliver synchronizations as fast as 500μs for up to 32 motion axes. Built on an open and highly modular architecture compliant with IEC 61131-3 standards, these flagship platforms provide machine builders (OEMs) with the processing speed, algorithmic precision, and anti-interference reliability required for smart manufacturing.
Product Features
Deterministic EtherCAT Real-Time Master with 500μs Cycle
Built-in hardware-level EtherCAT master stack delivers microsecond-level clock synchronization across decentralized servo networks. Sporting a minimum system scan cycle of just and supporting up to 32 independent motion axes, the platform eliminates transmission jitter to guarantee fluid, high-speed multi-axis interpolation.
IEC 61131-3 Compliant Motion Control Commands
Streamline your engineering phase. The platform natively supports standardized motion control function blocks compliant with IEC 61131-3 (including standard PLCopen MC commands). Engineers can easily configure point-to-point positioning, electronic cams, electronic gearing, linear/circular interpolation, and homing procedures via an intuitive programming environment.
Integrated High-Speed I/O & Dynamic Pulse Control
The PRO series features 16 high-speed digital inputs and 16 high-speed digital outputs natively. It supports up to 8 axes of local 200kHz high-speed pulse trains alongside 16-channel high-speed counting inputs, offering hybrid compatibility for systems utilizing both pulse-driven steppers and bus-driven EtherCAT servo drives.
Flexible Multi-Interface Communication Hub
Designed for seamless integration into enterprise SCADA and industrial networks. The controller integrates dual independent physical Ethernet ports, Type-C USB download interfaces, U-disk storage expansion, and dual RS485 channels, enabling simultaneous Modbus TCP/IP master/slave, Modbus RTU, and custom frame-by-frame data exchanges.
