Product Details

WPLAC-00 WPLAC-30 JBLKC-00 Product Description

The Fuji Electric WPLAC-00 is a high-performance industrial communication gateway engineered for the NB Series PLC platform, delivering seamless protocol bridging between field devices and upper-level control systems. Designed for demanding automation environments in power generation, petrochemicals, water treatment, and discrete manufacturing, the WPLAC-00 serves as the critical data link node that connects field-level sensors, actuators, and drives to SCADA, HMI, and MES layers through standardized industrial protocols including Modbus/TCP and PROFIBUS DP. Its companion modules — the WPLAC-30 and JBLKC-00 — extend network reach and I/O expansion capability within the same NB Series architecture, enabling scalable, multi-node factory communication without additional protocol converters.

In a modern smart factory, data does not flow in isolation. Every signal — from a proximity sensor on a conveyor line to a vibration transducer on a rotating shaft — must be captured, converted, transmitted, and acted upon in real time. The WPLAC-00 sits at the heart of this data chain, aggregating inputs from distributed remote I/O modules, translating legacy serial signals into Ethernet-compatible frames, and forwarding structured data packets to supervisory systems for real-time monitoring, alarm management, and predictive diagnostics. Whether integrated with a Fuji Electric MICREX-SX series controller, a third-party SCADA platform, or an edge computing gateway, the WPLAC-00 ensures that no data island forms between the field and the control room.

The WPLAC-00 is purpose-built to anchor the data flow architecture of a connected factory. At the field level, sensors — including pressure transmitters, flow meters, and temperature probes — feed analog and digital signals into remote I/O modules such as the Fuji Electric NW0P48R-31 remote I/O unit, which aggregates distributed inputs across the production floor. These signals are then routed through the WPLAC-00 gateway, which performs protocol encapsulation and forwards structured Modbus/TCP frames over the plant Ethernet backbone to the NB Series PLC host controller.

Within the PLC layer, the Fuji Electric MICREX-SX SPH3000 or equivalent NB Series CPU processes the incoming data, executes control logic, and generates command outputs that travel back down the same network path to actuators, variable frequency drives (VFDs), and motor control centers. For PROFIBUS DP segments — common in legacy installations with Siemens ET 200S remote I/O or ABB ACS880 drive networks — the WPLAC-00 acts as a DP master or slave interface, bridging the PROFIBUS segment to the Ethernet backbone without requiring a separate protocol converter.

At the supervisory layer, HMI panels such as the Fuji Electric V9 Series HMI connect directly to the Modbus/TCP network, pulling real-time process values — flow rates, temperatures, motor speeds, alarm states — and displaying them on operator screens. Simultaneously, a SCADA server running Wonderware InTouch or Ignition by Inductive Automation subscribes to the same Modbus/TCP data tags, enabling plant-wide visibility, trend logging, and alarm management from a centralized control room. The JBLKC-00 junction block module within the NB Series rack provides the physical I/O termination point, ensuring clean signal routing between field wiring and the communication backplane.

For edge computing and IIoT integration, an industrial edge gateway — such as a Moxa MGate MB3480 or equivalent Modbus-to-MQTT bridge — can sit downstream of the WPLAC-00, subscribing to Modbus/TCP registers and publishing structured JSON payloads to cloud platforms including AWS IoT Core or Microsoft Azure IoT Hub. This architecture enables remote diagnostics, OEE dashboards, and predictive maintenance analytics without modifying the existing PLC program or network topology. The WPLAC-30 extension module further expands the communication node count within the NB Series rack, supporting larger installations where multiple network segments must be managed from a single controller chassis.

Industrial Ethernet switches — such as the Hirschmann RS20 or Moxa EDS-308 managed switch — provide the network infrastructure layer, segmenting traffic between the field bus, the control network, and the enterprise IT backbone. VLAN configuration on these switches ensures that time-sensitive Modbus/TCP polling cycles are not disrupted by bulk data transfers from MES or ERP systems, maintaining deterministic communication latency below 10 ms for critical control loops.

Protocol Fragmentation: Many industrial sites operate a mix of legacy PROFIBUS DP devices alongside newer Ethernet-based controllers. Without a unified gateway, these segments remain isolated, creating data silos that prevent plant-wide visibility. The WPLAC-00 resolves this by acting as a transparent bridge between PROFIBUS DP field devices and Modbus/TCP Ethernet networks, eliminating the need for separate protocol converters and reducing wiring complexity.

Remote Monitoring Gaps: In unmanned substations, pump stations, or offshore platforms, operators cannot physically inspect equipment status. The WPLAC-00 enables remote diagnostics by exposing all NB Series I/O states and diagnostic registers as Modbus/TCP data points, accessible from any SCADA or HMI system on the network. Alarm conditions — motor overloads, sensor faults, communication timeouts — are immediately surfaced to the control room without requiring on-site intervention.

Production Line Transparency: Manufacturers seeking to implement OEE tracking or digital twin models require granular, timestamped data from every machine on the line. The WPLAC-00 provides the network interface that makes this data accessible, feeding cycle counts, downtime events, and quality signals from PLCs into MES databases and analytics platforms in real time.

System Scalability: As production capacity grows, new machines and sensors must be integrated without disrupting existing network infrastructure. The modular NB Series architecture — anchored by the WPLAC-00 and expandable via WPLAC-30 and JBLKC-00 modules — allows engineers to add network nodes incrementally, preserving existing wiring and programming investments while extending connectivity to new equipment.

Q1: What communication protocols does the WPLAC-00 support, and is it compatible with third-party SCADA systems? The WPLAC-00 supports Modbus/TCP over standard Ethernet and PROFIBUS DP for legacy field bus segments. It is compatible with any SCADA or HMI platform that supports Modbus/TCP as a data source, including Wonderware, Ignition, iFIX, and Citect. No proprietary driver is required for standard Modbus/TCP integration.

Q2: How does the WPLAC-00 handle network latency in time-critical control applications? The WPLAC-00 is designed for deterministic Modbus/TCP polling with typical cycle times well within the requirements of standard PLC scan rates. For applications requiring sub-10 ms response times, pairing the WPLAC-00 with a managed industrial Ethernet switch configured with QoS prioritization ensures that control traffic is not delayed by background data transfers.

Q3: Can the WPLAC-00 be integrated into an existing PROFIBUS DP network without replacing field devices? Yes. The WPLAC-00 can operate as a PROFIBUS DP master or slave, allowing it to join an existing PROFIBUS segment and bridge data to the Ethernet backbone without requiring replacement of existing DP-compatible field devices such as drives, remote I/O modules, or intelligent sensors.

Q4: What quality assurance and warranty coverage is provided with the WPLAC-00? Every WPLAC-00 unit supplied by NANKMOS is pre-shipment tested to verify communication functionality, protocol handshake integrity, and I/O response. All units carry a 12-month warranty covering manufacturing defects and communication failures under normal operating conditions. In-stock inventory ensures fast global dispatch with full traceability documentation.
