YOKOGAWA ATT4S-00 S2 Communication Gateway

Product Details

ATT4S-00 S2 Product Description

The Yokogawa ATT4S-00 S2 is a high-performance communication gateway engineered for the STARDOM FCN/FCJ autonomous controller platform, delivering seamless industrial data connectivity across multi-protocol factory environments. Designed to bridge field-level instrumentation with upper-layer SCADA, DCS, and MES systems, the ATT4S-00 S2 serves as a critical node in the smart factory data chain — enabling real-time signal acquisition, protocol translation, network transmission, and remote diagnostics from a single, compact module.

In modern industrial automation sites, data continuity is non-negotiable. The ATT4S-00 S2 addresses the persistent challenge of fragmented communication architectures by providing a stable, deterministic link between the STARDOM FCN controller rack and upstream supervisory systems. Whether deployed in oil & gas, chemical processing, power generation, or discrete manufacturing, this gateway ensures that every sensor reading, alarm event, and control command is accurately transmitted, logged, and acted upon — without latency or data loss.

The ATT4S-00 S2 sits at the heart of a layered industrial data architecture. At the field level, sensors — including Yokogawa EJA-series pressure transmitters and ADMAG AXF magnetic flowmeters — feed analog and digital signals into the STARDOM FCN controller rack. The ATT4S-00 S2 gateway module collects these signals, applies protocol normalization, and forwards structured data packets upstream via Ethernet to the plant's SCADA or DCS backbone.

Within the STARDOM FCN rack, the ATT4S-00 S2 works in close coordination with the FCN I/O modules and the FCN CPU unit (such as the FCN-100 or FCN-500 series), ensuring that all field data — temperature, pressure, flow, valve position — is aggregated and time-stamped before transmission. This tight integration eliminates the data gaps that commonly occur when legacy serial instruments are connected to modern Ethernet-based supervisory systems.

On the network layer, the ATT4S-00 S2 interfaces with industrial-grade managed switches — such as those from the Hirschmann RS20 or SCALANCE X series — to maintain network segmentation, redundancy, and Quality of Service (QoS) prioritization for time-critical control traffic. The gateway supports VLAN tagging and can operate within ring-topology networks for high-availability deployments.

At the supervisory level, the ATT4S-00 S2 delivers structured data directly to Yokogawa FAST/TOOLS SCADA or third-party HMI platforms via OPC-UA or Modbus TCP. Operators at the control room can monitor live process values, acknowledge alarms, and initiate remote setpoint adjustments — all without physical access to the field panel. This capability is further extended through edge gateway devices, where the ATT4S-00 S2 data stream can be routed to cloud-based analytics platforms for predictive maintenance and KPI dashboarding.

For distributed remote sites — such as pipeline monitoring stations or offshore substations — the ATT4S-00 S2 enables the STARDOM FCN/FCJ to operate as an autonomous RTU, executing local control logic while continuously reporting to the central SCADA via WAN or cellular uplink. This architecture is complemented by Yokogawa's STARDOM Network Package software, which provides centralized configuration, firmware management, and diagnostic visibility across all connected FCN/FCJ nodes.

In variable-speed drive applications, the ATT4S-00 S2 bridges Yokogawa-compatible VFDs and motor control centers into the SCADA data loop, enabling energy consumption monitoring and predictive fault detection. Combined with remote I/O modules such as the Yokogawa RM-series or third-party Wago 750-series I/O, the gateway creates a fully transparent data chain from motor shaft to management dashboard.

Industrial automation sites frequently suffer from protocol fragmentation — legacy Modbus RTU devices on the plant floor cannot natively communicate with modern OPC-UA-based SCADA systems. The ATT4S-00 S2 resolves this by acting as a transparent protocol bridge, converting serial Modbus frames into structured Ethernet packets without requiring PLC reprogramming or additional middleware servers.

Data silos are another persistent challenge. When field instruments, PLCs, and HMI systems operate on isolated networks, operators lose visibility into cross-system process states. The ATT4S-00 S2 consolidates these data streams into a unified network path, enabling plant-wide transparency and reducing the mean time to detect (MTTD) for process anomalies.

Remote monitoring and alarm management are significantly enhanced by the ATT4S-00 S2's deterministic communication cycle. Alarm events generated at the FCN controller level are immediately propagated to the SCADA alarm management system, with full timestamp and priority tagging. This eliminates the alarm flooding and missed-event issues that plague sites relying on polling-based legacy gateways.

For production line transparency, the ATT4S-00 S2 enables real-time OEE (Overall Equipment Effectiveness) data collection by feeding machine status, cycle counts, and downtime events directly into MES or ERP systems. System expansion is equally straightforward — additional FCN I/O modules or remote FCJ nodes can be added to the network without disrupting existing communication paths, thanks to the gateway's modular architecture and hot-swap capability.

Q1: What communication protocols does the Yokogawa ATT4S-00 S2 support? The ATT4S-00 S2 supports Modbus TCP/RTU, OPC-UA, FOUNDATION Fieldbus, HART pass-through, and Ethernet/IP, making it compatible with the majority of industrial SCADA, DCS, and HMI platforms deployed in process and discrete manufacturing environments.

Q2: How does the ATT4S-00 S2 ensure network stability in high-noise industrial environments? The module is designed to operate within the STARDOM FCN rack's electrically isolated backplane, providing inherent noise immunity. When deployed with managed industrial switches supporting RSTP/ring redundancy, the gateway maintains communication continuity even during single-point network failures, with sub-50ms failover recovery.

Q3: Can the ATT4S-00 S2 support remote diagnostics and firmware updates without on-site access? Yes. Through the STARDOM Network Package and OPC-UA connectivity, authorized engineers can remotely access gateway diagnostics, review communication logs, check link status, and push configuration updates — eliminating the need for costly site visits during routine maintenance or troubleshooting.

Q4: What warranty and pre-shipment testing does NANKMOS provide for the ATT4S-00 S2? Every Yokogawa ATT4S-00 S2 unit supplied by NANKMOS is covered by a 12-month warranty and undergoes pre-shipment functional testing to verify communication integrity, protocol handshake, and hardware condition. In-stock units are available for immediate dispatch to minimize project downtime.
