SST (Woodhead/Molex) 5136-CN-VM Communication Gateway

Product Details

5136-CN-VM Product Description

The SST 5136-CN-VM is a high-performance ControlNet communication gateway from the SST Series, engineered by SST (Woodhead/Molex) to serve as the backbone of industrial data exchange in smart manufacturing environments. Designed for seamless integration between field-level devices and supervisory control systems, the 5136-CN-VM enables deterministic, real-time data transfer across ControlNet-based automation architectures — making it an essential component for factories pursuing digital transformation, production transparency, and remote diagnostic capability.

At NANKMOS, every SST 5136-CN-VM unit is sourced from verified supply channels, pre-shipment tested, and backed by a 12-month warranty. Global logistics via DHL and FedEx ensure rapid delivery to manufacturing sites across Asia, Europe, and the Americas.

In a modern smart factory, the SST 5136-CN-VM occupies a critical position in the industrial data chain — acting as the communication bridge between field instrumentation, programmable logic controllers, and upper-level supervisory systems. The data flow begins at the sensor and actuator layer, where devices such as pressure transmitters, flow meters, and motor-driven actuators generate continuous process signals. These signals are collected by remote I/O modules — for example, Allen-Bradley 1794-AENT or 1756-IB16 digital input cards — and transmitted upstream via the ControlNet backbone managed by the 5136-CN-VM.

Within the PLC control layer, the gateway interfaces directly with Rockwell Automation ControlLogix or CompactLogix processors, enabling deterministic cyclic data exchange at configurable RPI (Requested Packet Interval) rates. This ensures that time-critical process variables — motor speed feedback from PowerFlex 755 variable frequency drives, valve position signals, or conveyor encoder data — are delivered to the controller with minimal latency and zero packet loss under normal network conditions.

Moving up the architecture, the 5136-CN-VM facilitates data handoff to SCADA platforms such as Rockwell FactoryTalk View SE or Wonderware InTouch, where operators gain real-time visibility into production KPIs, alarm states, and equipment health dashboards. HMI terminals — including PanelView Plus 7 or similar operator interfaces — receive live tag data through the ControlNet network, enabling floor-level operators to monitor and respond to process deviations without delay.

For facilities deploying edge computing strategies, the SST 5136-CN-VM can be paired with industrial edge gateways such as the Moxa MGate series or Advantech WISE-5000 to extract ControlNet data and forward it to cloud-based MES or ERP platforms via OPC-UA or MQTT. This creates a seamless data pipeline from the physical production floor to enterprise dashboards, enabling predictive maintenance analytics, OEE tracking, and energy consumption monitoring across multiple production lines.

Industrial Ethernet switches — such as the Cisco IE-2000 or Hirschmann MACH 100 — provide the network infrastructure backbone that connects ControlNet segments to broader plant-wide Ethernet/IP topologies. When combined with the SST 5136-CN-VM, these switches enable a layered network architecture that supports both legacy ControlNet devices and modern Ethernet-based automation components within the same facility.

Power reliability for the communication infrastructure is ensured through industrial DIN-rail power supplies such as the Phoenix Contact QUINT series, which provide stable 24VDC to the gateway and associated network components. This end-to-end design — from sensor signal to cloud data point — represents the complete connected factory data flow that the SST 5136-CN-VM is built to support.

Many industrial facilities face persistent challenges when integrating legacy ControlNet infrastructure with modern automation platforms. The SST 5136-CN-VM directly addresses the most common data gap scenarios encountered on the plant floor:

Protocol Fragmentation: Sites running mixed networks — ControlNet alongside Modbus RTU, PROFIBUS DP, or DeviceNet — often struggle with data islands where process information cannot flow freely between subsystems. The 5136-CN-VM, when deployed alongside protocol converters or multi-protocol gateways, eliminates these barriers by providing a stable, standards-compliant ControlNet interface that upstream systems can reliably query.

Remote Monitoring Blind Spots: Without a robust ControlNet gateway, remote diagnostic access to field devices is limited. The 5136-CN-VM enables SCADA systems to poll device-level diagnostics — including drive fault codes from PowerFlex VFDs, I/O module health status, and network node availability — providing maintenance teams with actionable data before equipment failures escalate to unplanned downtime.

Production Line Transparency: Manufacturers pursuing lean manufacturing or Industry 4.0 initiatives require granular, real-time production data. The 5136-CN-VM feeds this data continuously to MES platforms, enabling shift-by-shift OEE analysis, cycle time tracking, and quality event correlation without manual data collection.

Alarm Management and Traceability: Alarm floods and untracked fault events are a major source of production loss. By maintaining a stable ControlNet data link, the 5136-CN-VM ensures that alarm timestamps, device fault codes, and process exceedance events are captured accurately in the historian, supporting root cause analysis and regulatory compliance reporting.

Network Scalability: As production capacity expands, adding new ControlNet nodes — additional remote I/O racks, new drive nodes, or supplementary HMI stations — is straightforward with the 5136-CN-VM managing network scheduling. The gateway supports up to 99 nodes per network segment, providing substantial headroom for future expansion without requiring a network redesign.

Q1: What communication latency can be expected with the SST 5136-CN-VM on a ControlNet network? ControlNet is a deterministic protocol, meaning the 5136-CN-VM delivers scheduled data at a fixed, configurable RPI — typically ranging from 2ms to 500ms depending on network load and node count. For most process control applications, an RPI of 10–20ms provides real-time responsiveness with negligible jitter, making it suitable for motion coordination, drive control, and safety-critical I/O applications.

Q2: Is the SST 5136-CN-VM compatible with both legacy and modern Rockwell Automation platforms? Yes. The 5136-CN-VM is designed for broad compatibility across the Rockwell Automation ControlNet ecosystem, including legacy PLC-5 and SLC 500 platforms as well as current ControlLogix and CompactLogix systems. It integrates with RSNetWorx for ControlNet configuration software, ensuring straightforward commissioning and network scheduling setup.

Q3: How does NANKMOS ensure the SST 5136-CN-VM is functional before shipment? Every unit undergoes a pre-shipment functional test at our facility, verifying communication interface integrity, firmware version, and hardware condition. Units are shipped with a 12-month warranty covering manufacturing defects and communication failures. A test report is available upon request for quality-critical procurement processes.

Q4: Can the SST 5136-CN-VM support network expansion without disrupting existing ControlNet operations? Yes. Adding new nodes to an existing ControlNet network managed by the 5136-CN-VM requires only a network reschedule via RSNetWorx, which can be performed online with minimal disruption to running processes. The gateway's support for up to 99 nodes per segment ensures that most facility expansion projects can be accommodated without hardware replacement or network segmentation changes.
