T2DD6-17099 0041-94358 0041-64758 0.2~100 ML/MIN VP-2 Product Description

The Kokusai T2DD6 is a precision-engineered industrial network interface and protocol gateway designed for semiconductor furnace systems and advanced process automation environments. With a rated flow range of 0.2–100 mL/min and a VP-2 valve configuration, the T2DD6 bridges field-level instrumentation with upper-layer control and monitoring systems — enabling seamless data flow across the full automation stack. Whether deployed in diffusion furnace lines, CVD chambers, or gas delivery subsystems, the T2DD6 delivers the network stability, protocol compatibility, and real-time data transparency that modern smart factories demand.

In a modern semiconductor fab or process automation site, data integrity across every node of the control hierarchy is non-negotiable. The Kokusai T2DD6 sits at the intersection of field instrumentation and supervisory control, acting as the critical communication bridge that keeps process data flowing without interruption.

At the field level, mass flow controllers (MFCs) and gas delivery modules generate continuous analog and digital signals — flow rates, valve states, pressure readings, and fault flags. The T2DD6 captures these signals and translates them into structured data packets compatible with upstream PLC controllers such as the Kokusai SigmaFurnace PLC platform and third-party Siemens S7 or Allen-Bradley ControlLogix systems integrated into the fab's automation backbone. This protocol translation layer eliminates the data gaps that commonly arise when legacy field devices communicate with modern Ethernet-based control networks.

From the PLC layer, process data is forwarded via Industrial Ethernet to remote I/O modules and distributed control nodes positioned across the furnace bay. These nodes relay real-time status to HMI panels — typically 10–15 inch touchscreen terminals mounted at the furnace station — where operators monitor gas flow curves, temperature profiles, and recipe execution status. The T2DD6's stable serial-to-network conversion ensures that HMI refresh rates remain consistent even under high-cycle production loads, preventing display lag that could mask developing process faults.

At the supervisory layer, the T2DD6 feeds structured data into SCADA platforms such as Wonderware InTouch, Ignition by Inductive Automation, or Kokusai's proprietary furnace management software. SCADA integration enables plant-wide visibility: engineers can overlay T2DD6-sourced flow data with temperature trends from thermocouple input modules, pressure readings from capacitance manometer transmitters, and recipe parameters from the batch management system — all on a unified dashboard. This multi-source data aggregation is the foundation of real-time process transparency in a smart factory.

For facilities operating variable-speed exhaust or gas abatement systems, the T2DD6 also interfaces with variable frequency drives (VFDs) controlling pump and blower motors. By relaying flow demand signals from the MFC network to the VFD control loop, the gateway enables dynamic speed adjustment that reduces energy consumption during idle or low-flow process steps — a key efficiency gain in high-volume semiconductor production.

Edge connectivity is handled through industrial edge gateways that aggregate T2DD6 data streams alongside inputs from industrial Ethernet switches (managed, DIN-rail mounted, with PROFINET or EtherNet/IP support) deployed throughout the furnace bay. These switches provide the network segmentation and redundancy needed to isolate process-critical traffic from general plant IT traffic, ensuring that a network event in the office segment never disrupts furnace recipe execution. The edge gateway then forwards normalized data to cloud analytics platforms or on-premise MES/ERP systems for production reporting, yield analysis, and predictive maintenance scheduling.

Power integrity for the T2DD6 and its associated field devices is maintained by DIN-rail industrial power supplies with wide-input AC ranges and 24 VDC regulated outputs — ensuring stable operation across the voltage fluctuations common in heavy industrial environments. Upstream, 24 VDC sensor power distributors provide individually fused outputs to each field instrument, enabling fault isolation without shutting down the entire instrumentation loop.

Protocol fragmentation is one of the most persistent challenges in semiconductor and process automation. Legacy Kokusai furnace systems often use proprietary serial communication formats that are incompatible with modern Ethernet-based SCADA and MES platforms. The T2DD6 resolves this by acting as a transparent protocol converter, presenting field data in standard formats that any supervisory system can consume — without requiring firmware changes to the furnace controller or replacement of existing field wiring.

Data silos emerge when individual process tools operate as isolated islands, each with its own local HMI and no connection to the plant-wide data infrastructure. By integrating the T2DD6 into the furnace network architecture, operators gain a single pane of glass across multiple tools — correlating gas flow data from the T2DD6 with wafer temperature profiles, boat loading status, and recipe version history in one unified view. This cross-tool visibility is essential for root-cause analysis when yield excursions occur.

Remote monitoring and diagnostics become practical when the T2DD6 is connected to a SCADA or edge gateway with remote access capability. Maintenance engineers can review real-time flow curves, valve cycle counts, and alarm histories from off-site locations — reducing the need for on-site intervention during off-hours and enabling faster mean-time-to-repair (MTTR) for flow-related process faults. Alarm thresholds configured in the SCADA layer trigger automatic notifications via email or SMS when T2DD6-monitored parameters deviate from recipe setpoints.

Production line transparency is achieved by feeding T2DD6 data into OEE (Overall Equipment Effectiveness) dashboards that track availability, performance, and quality metrics at the tool level. Plant managers can identify underperforming furnace zones, correlate gas flow anomalies with batch yield data, and prioritize preventive maintenance based on actual usage patterns rather than fixed time intervals.

System scalability is supported by the T2DD6's modular communication architecture. As fab capacity expands, additional T2DD6 units can be added to new furnace tools and integrated into the existing SCADA and edge network infrastructure without redesigning the communication backbone — protecting the initial integration investment and reducing commissioning time for new equipment.

Q1: What communication protocols does the Kokusai T2DD6 support, and is it compatible with modern SCADA platforms? The T2DD6 supports RS-232C and RS-485 serial interfaces with Modbus RTU/TCP compatibility (inferred from Kokusai platform architecture), enabling integration with leading SCADA platforms including Wonderware, Ignition, and iFIX. For proprietary Kokusai bus protocols, a dedicated protocol converter or OPC-UA gateway may be required to bridge to third-party supervisory systems.

Q2: How does the T2DD6 ensure network stability in high-EMI semiconductor fab environments? The T2DD6 is designed for industrial-grade operation in process environments where electromagnetic interference from RF generators, plasma sources, and high-current power supplies is common. Shielded cable connections, optically isolated I/O, and robust enclosure grounding are recommended installation practices to maintain signal integrity and network stability.

Q3: Can the T2DD6 support remote diagnostics and alarm management without on-site access? Yes. When integrated with an edge gateway or SCADA system with remote access capability, the T2DD6 enables off-site monitoring of flow rates, valve states, and alarm conditions. Engineers can review historical trend data, acknowledge alarms, and adjust setpoints remotely — reducing unplanned downtime and travel costs for routine diagnostics.

Q4: What is the warranty coverage, and has the unit been tested prior to shipment? All Kokusai T2DD6 units supplied by NANKMOS are covered by a 12-month warranty from the date of shipment. Each unit undergoes pre-shipment functional testing to verify communication interface integrity, flow signal accuracy, and valve response — ensuring that the unit arrives ready for integration without additional incoming inspection delays.
