Product Details

XCX300 XCS300 Product Description

The Schleicher XCX300 is a high-performance CPU module engineered for seamless deployment within the XCS300 modular PLC platform. Designed to serve as the central processing unit of a distributed control architecture, the XCX300 delivers deterministic scan-cycle execution, robust I/O coordination, and multi-layer communication capability across demanding industrial environments. Whether integrated into a greenfield automation project or retrofitted into an existing XCS300 rack system, this CPU module provides the processing backbone required for reliable, scalable, and maintainable control system design.

At NANKMOS, every XCX300 unit is sourced from verified supply channels, subjected to pre-shipment functional testing, and backed by a 12-Month Warranty. Our engineering team supports contextual integration across control layers — from rack assembly and I/O mapping to communication protocol configuration and HMI binding — ensuring that your system goes live with confidence.

The XCX300 CPU module is not a standalone component — it is the processing core of a fully coordinated XCS300 automation platform. In a complete control cabinet deployment, the XCX300 operates in conjunction with a range of system-matched components that together define the performance, reliability, and scalability of the entire installation.

At the power layer, the XCS300-series rack power supply module provides regulated 24 VDC to the backplane, ensuring stable voltage delivery to the CPU and all connected I/O modules. Upstream, a dedicated 24 VDC DIN-rail power supply — such as a Puls or Phoenix Contact unit — conditions incoming AC power before it reaches the rack. At the I/O layer, digital input modules (e.g., XCS300 DI16 or DI32 variants) and digital output modules (e.g., XCS300 DO16 relay or transistor types) expand the XCX300's field connectivity, while analog input and output modules handle process variable acquisition and actuator control for PID loops and flow regulation.

For communication and networking, the XCX300 supports PROFIBUS-DP master/slave configurations, enabling integration with distributed field devices such as Siemens ET 200 remote I/O stations, ABB AC500 I/O expansions, or third-party PROFIBUS slaves. Where Ethernet-based communication is required, an XCS300-compatible Ethernet communication module or gateway bridges the CPU to MODBUS TCP, PROFINET, or OPC-UA supervisory networks. This makes the XCX300 fully compatible with modern SCADA platforms and MES integration layers.

At the HMI layer, the XCX300 connects to operator panels via serial or Ethernet links. Compatible HMI units — including Schleicher's own operator terminals or third-party panels from Weintek, Siemens TP series, or Schneider Magelis — provide real-time process visualization, alarm management, and parameter adjustment without interrupting CPU scan cycles. For motion and drive control, the XCX300 can coordinate with variable frequency drives (VFDs) via PROFIBUS-DP or analog reference signals, enabling closed-loop speed and torque regulation in pump, fan, and conveyor applications.

At the protection layer, the XCX300 architecture supports integration with safety relays, circuit breakers, and surge protection devices within the same control cabinet. Terminal blocks — such as Phoenix Contact PTFIX or Weidmüller WDU series — provide organized field wiring termination, while signal isolators and repeaters maintain signal integrity across long cable runs or electrically noisy environments. Together, these components form a coherent, maintainable, and expandable automation platform anchored by the XCX300 CPU.

The Schleicher XCX300 CPU module has been deployed across a broad spectrum of industrial sectors, each demanding high reliability, deterministic control, and long-term serviceability.

In manufacturing and discrete automation, the XCX300 manages multi-axis sequencing, conveyor synchronization, and assembly line interlocking. Its modular I/O architecture allows rapid reconfiguration as production lines evolve, reducing engineering change-order costs and minimizing downtime during retooling. In power generation and electrical distribution, the XCX300 serves as the primary controller for generator protection panels, transformer monitoring systems, and switchgear automation, where deterministic scan cycles and robust communication are non-negotiable.

In petrochemical and process industries, the XCX300 handles continuous process control tasks including flow regulation, pressure management, temperature loop control, and emergency shutdown sequencing. Its compatibility with PROFIBUS-DP field instruments — including pressure transmitters, flow meters, and control valves — makes it a natural fit for DCS-adjacent PLC architectures. In water and wastewater treatment, the XCX300 controls pump stations, dosing systems, and filtration sequences, often operating in remote or unmanned facilities where diagnostic efficiency and low-maintenance design are critical.

In mining and metallurgy, the XCX300 withstands high-vibration, high-dust environments when properly housed, managing crusher controls, conveyor drives, and ore processing sequences. In marine and offshore applications, the XCX300 is integrated into vessel automation panels for ballast control, engine room monitoring, and cargo handling systems, where compact rack design and reliable communication are essential. In packaging and material handling, the XCX300 coordinates high-speed pick-and-place sequences, label application, and end-of-line inspection systems, interfacing with servo drives and vision systems via high-speed I/O and communication modules.

Q1: Is the XCX300 compatible with existing XCS300 rack systems, and can it be added to an operational installation without full system shutdown? A: Yes. The XCX300 is designed as a system-matched CPU for the XCS300 backplane architecture. It is physically and electrically compatible with all standard XCS300 rack configurations. In most cases, CPU replacement or addition can be performed during a scheduled maintenance window with a controlled power-down sequence. NANKMOS recommends verifying firmware revision compatibility between the XCX300 and existing I/O modules before installation. Our technical team provides pre-shipment configuration guidance as part of the 12-Month Warranty support package.

Q2: What communication protocols does the XCX300 support, and how does it integrate with SCADA or MES systems? A: The XCX300 natively supports PROFIBUS-DP (master and slave modes) and serial communication via RS-232/RS-485. With the addition of an XCS300-compatible Ethernet gateway module, the platform extends to MODBUS TCP, PROFINET, and OPC-UA, enabling direct integration with SCADA platforms such as Wonderware, Ignition, or WinCC, as well as MES and ERP data layers. Contextual Integration support from NANKMOS covers protocol mapping, tag configuration, and communication diagnostics during commissioning.

Q3: What does the 12-Month Warranty cover, and what is the typical lead time for XCX300 units from NANKMOS inventory? A: The NANKMOS 12-Month Warranty covers functional defects identified under normal operating conditions, including CPU processing failures, communication port malfunctions, and backplane interface faults. Each unit undergoes pre-shipment functional testing before dispatch. For in-stock XCX300 units, standard lead time is 3–7 business days for international shipments, with expedited options available. For long-term project requirements, NANKMOS offers inventory reservation agreements to ensure supply continuity across multi-phase engineering projects.
