Product Details

FEG-S032-J001 Product Description

The GE NEGTBCSA1 (FEG-S032-J001) is a high-performance industrial Ethernet TCP/IP network interface module engineered for GE Series 90 PLC platforms. Designed to bridge the gap between legacy field-level controllers and modern smart factory architectures, this gateway enables seamless, real-time data exchange across every layer of the industrial automation stack — from sensor-level signal acquisition all the way to enterprise SCADA dashboards and cloud-based analytics platforms.

In today's connected manufacturing environment, the ability to move data reliably from a Series 90 PLC rack to a supervisory control system is not optional — it is the backbone of operational transparency. The NEGTBCSA1 delivers exactly that: a deterministic, low-latency Ethernet link that supports SRTP (Service Request Transport Protocol) and Modbus TCP, enabling interoperability with a broad ecosystem of HMI panels, SCADA servers, historian databases, and edge computing nodes.

The NEGTBCSA1 sits at the heart of a layered industrial data architecture. At the field level, discrete sensors, analog transmitters, and actuator feedback signals are wired into GE Series 90 I/O modules — such as the IC693MDL645 discrete input module or the IC693ALG222 analog input module — which feed real-time process values into the Series 90 CPU. The NEGTBCSA1 then acts as the network bridge, packaging that PLC data into standard Ethernet frames and routing it upstream to the control and supervisory layers.

At the control layer, the gateway communicates directly with GE Proficy HMI/SCADA — iFIX or CIMPLICITY — enabling operators to visualize live production data, configure alarm thresholds, and acknowledge fault conditions from centralized workstations. The SRTP protocol ensures that data integrity is maintained even across congested plant-floor networks, while Modbus TCP compatibility allows the NEGTBCSA1 to exchange data with third-party SCADA platforms, energy management systems, and OPC-DA/UA servers without additional middleware.

For distributed control architectures, the NEGTBCSA1 enables peer-to-peer communication between multiple Series 90 PLC racks — for example, linking a IC693CPU374 master controller with remote expansion racks equipped with IC693CHS391 expansion chassis. This topology is common in large-scale process plants where a single PLC rack cannot accommodate all I/O points, and where deterministic data exchange between controllers is critical for coordinated machine sequencing.

Edge computing integration is another key strength. By connecting the NEGTBCSA1 to an industrial edge gateway — such as a Moxa MGate or Advantech WISE series — raw PLC data can be pre-processed locally before being forwarded to cloud platforms like AWS IoT, Azure IoT Hub, or GE Predix. This edge-to-cloud pipeline supports predictive maintenance algorithms, OEE (Overall Equipment Effectiveness) dashboards, and digital twin simulations without burdening the PLC CPU with additional communication overhead.

Industrial managed switches — such as the IC693CMM321 communications coprocessor or third-party DIN-rail Ethernet switches — segment the plant network into logical zones, ensuring that SCADA polling traffic does not interfere with time-critical PLC scan cycles. VLAN configuration and QoS prioritization further protect the integrity of the NEGTBCSA1's data streams in high-traffic environments.

Variable frequency drives (VFDs) and servo controllers connected via Modbus TCP — including GE's own AF-600 FP drive series — can be monitored and parameterized through the NEGTBCSA1 link, enabling closed-loop speed control feedback to be logged in the historian and visualized on the SCADA trend screen. This eliminates the need for dedicated drive communication cards in many retrofit scenarios.

Protocol fragmentation is one of the most persistent challenges in brownfield automation environments. Legacy Series 90 systems often coexist with newer Ethernet-native devices that speak Modbus TCP, EtherNet/IP, or OPC-UA natively. The NEGTBCSA1 resolves this by providing a standards-compliant Ethernet interface that most modern SCADA and HMI platforms can poll directly, eliminating the need for costly protocol converters or middleware servers.

Data silos — where PLC data is trapped in isolated controller memory with no path to the supervisory layer — are eliminated by the NEGTBCSA1's always-on Ethernet connection. Once configured, the module continuously exposes the PLC's register map to authorized network clients, enabling historian software to log every process variable at configurable scan rates without any PLC program modification.

Remote monitoring and diagnostics become practical with the NEGTBCSA1 in place. Maintenance engineers can use standard Ethernet-based tools — including GE's Proficy Machine Edition programming software — to connect remotely to the Series 90 CPU over a VPN tunnel, upload/download programs, force I/O points for troubleshooting, and review fault tables without traveling to the plant floor. This capability is especially valuable for multi-site operations where a single engineering team supports dozens of geographically dispersed production lines.

Production line transparency is achieved by mapping PLC data tags to SCADA displays in real time. Alarm events — such as motor overloads, conveyor jams, or temperature exceedances — are transmitted from the Series 90 CPU through the NEGTBCSA1 to the SCADA alarm server within milliseconds, enabling rapid operator response and accurate downtime tracking. Historical alarm logs support root-cause analysis and regulatory compliance reporting.

System scalability is built into the NEGTBCSA1's design. As production capacity expands, additional Series 90 racks can be networked through the same Ethernet infrastructure, and the SCADA system can be extended to monitor new data points without hardware changes to the gateway module itself.

Q1: What communication protocols does the GE NEGTBCSA1 (FEG-S032-J001) support? The NEGTBCSA1 supports Ethernet TCP/IP with GE's native SRTP (Service Request Transport Protocol) and Modbus TCP. This dual-protocol capability allows it to communicate natively with GE Proficy SCADA/HMI systems while also interoperating with third-party supervisory platforms, OPC servers, and energy management systems that use Modbus TCP as their standard polling protocol.

Q2: How does the NEGTBCSA1 perform in high-traffic industrial networks? The module is designed for deterministic industrial Ethernet environments. It supports 10/100 Mbps auto-negotiation and is compatible with managed switch configurations that implement VLAN segmentation and QoS prioritization. In properly segmented networks, the NEGTBCSA1 maintains stable, low-latency communication even when coexisting with high-bandwidth video surveillance, wireless access points, or IT network traffic on the same physical infrastructure.

Q3: Can the NEGTBCSA1 be used for remote diagnostics and programming of Series 90 PLCs? Yes. Once the NEGTBCSA1 is connected to the plant Ethernet network (or a VPN-secured WAN), GE Proficy Machine Edition can establish a remote programming session with the Series 90 CPU through the gateway. Engineers can monitor ladder logic execution, modify data registers, force discrete outputs, and download updated programs — all without physical access to the PLC rack. This capability significantly reduces maintenance response times for geographically distributed installations.

Q4: What warranty and pre-shipment testing does NANKMOS provide for the NEGTBCSA1? Every NEGTBCSA1 unit shipped by NANKMOS is covered by a 12-Month Warranty and undergoes pre-shipment functional testing to verify Ethernet communication, protocol handshake, and module initialization. In-stock units are available for same-week dispatch, supporting urgent MRO (Maintenance, Repair, and Operations) requirements and minimizing unplanned production downtime.
