0160B24F2 02-324555D01 EX160-SDN1A 0190-13031 0270-76008 Product Description

The SMC EX160-SDN1A (ASM-0160B24F2-02) is a high-performance DeviceNet industrial network interface designed to bridge field-level pneumatic valve terminals with upper-level control and monitoring systems in smart factory environments. As part of SMC's proven EX160 series, this unit delivers deterministic, real-time I/O communication across DeviceNet-based automation architectures — enabling seamless data flow from actuators and sensors on the shop floor all the way to SCADA platforms, HMI dashboards, and enterprise MES systems.

In modern industrial facilities, the demand for transparent, connected production lines has never been greater. The EX160-SDN1A answers this challenge by acting as a compact yet powerful gateway node on the DeviceNet network, allowing PLC controllers — such as Allen-Bradley ControlLogix or CompactLogix platforms — to directly address and control SMC valve manifold outputs while simultaneously receiving real-time diagnostic feedback. This bidirectional data exchange eliminates the traditional blind spots between pneumatic actuation layers and digital control layers, forming the backbone of a truly integrated smart factory data chain.

Signal acquisition begins at the field device level, where sensors, proximity switches, and pressure transducers feed status data into the EX160-SDN1A's I/O nodes. The unit consolidates these discrete and analog signals and transmits them over the DeviceNet trunk line with cycle times optimized for time-sensitive automation sequences. Upstream, a DeviceNet scanner module within the PLC rack — such as a 1756-DNB or equivalent — polls the EX160-SDN1A at configurable rates, ensuring that valve states, fault flags, and I/O status are always current within the control program. This architecture supports up to 64 nodes on a single DeviceNet segment, making it straightforward to scale from a single valve island to a multi-zone pneumatic control network without redesigning the communication backbone.

For facilities running Rockwell Automation's Studio 5000 or RSLogix 5000 environment, the EX160-SDN1A integrates via standard EDS (Electronic Data Sheet) files, simplifying commissioning and reducing engineering time. The same DeviceNet segment can simultaneously carry data from SMC's SI unit series, remote I/O blocks, and third-party DeviceNet-compatible devices such as photoelectric sensors, flow controllers, and variable frequency drives — all visible within a single network topology. This unified view is critical for SCADA systems like FactoryTalk View or Wonderware InTouch, which aggregate tag data from the PLC to render real-time process graphics, trend charts, and alarm annunciators.

Remote diagnostics is a core strength of the EX160-SDN1A deployment model. Because valve coil status, short-circuit detection, and communication health are all mapped as DeviceNet I/O data, maintenance engineers can monitor equipment condition from a central control room or even via remote VPN access — without walking the production floor. When a valve solenoid develops an open-circuit fault or a pneumatic manifold loses supply pressure, the EX160-SDN1A immediately reflects the change in its I/O image table, triggering alarm logic in the PLC and surfacing a notification on the HMI operator panel. This closed-loop alarm feedback dramatically reduces mean time to repair (MTTR) and supports predictive maintenance strategies aligned with Industry 4.0 objectives.

Data visualization is further enhanced when the DeviceNet network is integrated with an edge gateway device — such as an industrial IoT router or protocol converter supporting OPC-UA or MQTT — allowing the EX160-SDN1A's I/O data to be pushed to cloud-based analytics platforms or on-premise data historians. In such architectures, the EX160-SDN1A serves as the originating data source for pneumatic system KPIs: cycle counts, valve actuation frequency, fault occurrence rates, and uptime percentages. These metrics feed dashboards that plant managers use to benchmark line efficiency and plan preventive maintenance windows.

System expansion is equally straightforward. The EX160 series supports modular I/O expansion, meaning additional valve stations or discrete I/O modules can be added to the manifold assembly without replacing the network interface unit. Combined with SMC's EX600 series distributed I/O blocks and compatible fieldbus power supplies, the EX160-SDN1A forms the nucleus of a scalable pneumatic control network that grows with production demands. For multi-line facilities, multiple EX160-SDN1A units can coexist on the same DeviceNet segment, each assigned a unique MAC ID, providing granular zone-level control and diagnostics across the entire plant floor.

Every unit supplied by NANKMOS undergoes pre-shipment functional verification, confirming DeviceNet communication integrity, I/O mapping accuracy, and physical connector condition before dispatch. Stock is maintained for rapid fulfillment, and all units are covered by a 12-month warranty against manufacturing defects — ensuring your automation investment is protected from day one of installation.

A typical smart factory deployment of the EX160-SDN1A begins at the pneumatic valve island, where the unit interfaces directly with SMC's SY series solenoid valve manifolds or VQC series valve banks. Discrete output signals from the PLC — routed through a 1756-DNB DeviceNet scanner in a ControlLogix chassis — travel down the DeviceNet trunk cable to the EX160-SDN1A, which decodes the network commands and energizes the corresponding valve coils with 24 VDC switching. Simultaneously, input feedback from reed switches, magnetic sensors, or SMC's D-M9 series cylinder position sensors is captured by the EX160-SDN1A's input nodes and returned upstream to the PLC's input image table in the same DeviceNet poll cycle.

At the network layer, the DeviceNet segment may also carry data from SMC's EX500 series gateway units deployed on adjacent machine cells, as well as from third-party DeviceNet nodes such as Balluff BIS RFID readers, Turck multiprotocol I/O blocks, or Cognex vision system discrete outputs — all coexisting on the same 5-wire bus. A DeviceNet-to-EtherNet/IP linking device, such as an HMS Anybus Communicator or a Rockwell 1788-EN2DN module, can bridge the DeviceNet segment to the plant's Ethernet backbone, making the EX160-SDN1A's I/O data accessible to FactoryTalk View SCADA, Ignition SCADA, or any OPC-DA/UA server without requiring a separate communication path.

For edge analytics, an industrial IoT gateway — such as a Moxa UC-8100 or Advantech WISE-5000 series edge controller — can subscribe to the OPC-UA tags derived from the EX160-SDN1A's I/O map, forwarding valve cycle counts and fault event logs to a cloud data historian or on-premise InfluxDB time-series database. This data pipeline supports real-time dashboards in Grafana or Wonderware System Platform, giving process engineers visibility into pneumatic system health across every production shift. The complete data chain — from valve coil actuation through DeviceNet polling, PLC processing, SCADA visualization, and edge analytics — represents the connected factory architecture that the EX160-SDN1A is purpose-built to enable.

Many manufacturing sites still operate with fragmented automation layers: pneumatic valve terminals that have no network connectivity, PLC programs that cannot confirm actuator states, and maintenance teams that rely on manual inspection to diagnose faults. The EX160-SDN1A directly addresses these data gaps by providing a standardized DeviceNet interface that integrates pneumatic control into the plant's existing network infrastructure without requiring proprietary software or custom wiring harnesses.

Protocol fragmentation is resolved by the EX160-SDN1A's native DeviceNet compliance, which ensures plug-and-play compatibility with any DeviceNet master scanner — eliminating the need for custom protocol converters between the PLC and the valve terminal. Data island problems are eliminated because every valve output and sensor input is mapped to a standard DeviceNet I/O assembly object, making the data immediately available to SCADA historians, alarm management systems, and MES platforms through the PLC's tag database.

Remote monitoring challenges are overcome through the EX160-SDN1A's diagnostic I/O mapping: short-circuit detection, communication timeout flags, and power supply status are all surfaced as readable bits in the PLC program, enabling remote engineers to assess field device health via VPN without dispatching technicians. Production line transparency is achieved by integrating the EX160-SDN1A's data into HMI faceplate displays that show real-time valve states, cycle counts, and fault histories — giving operators and supervisors a live view of pneumatic system performance. System expansion is supported by the modular EX160 architecture, which allows additional valve stations to be added to the manifold and automatically recognized by the DeviceNet network without reconfiguring the master scanner's node table.

Q1: What is the maximum DeviceNet network length supported when using the EX160-SDN1A?DeviceNet network length depends on the selected baud rate. At 125 kbps, the trunk cable can extend up to 500 meters; at 250 kbps, up to 250 meters; and at 500 kbps, up to 100 meters. Drop lines from the trunk to the EX160-SDN1A should not exceed 6 meters at 500 kbps. Proper termination resistors (121 Ω) must be installed at both ends of the trunk to prevent signal reflections and ensure communication stability.

Q2: Is the EX160-SDN1A compatible with non-Rockwell DeviceNet masters?Yes. The EX160-SDN1A is a standard DeviceNet slave device compliant with the ODVA DeviceNet specification. It is compatible with any DeviceNet master scanner that supports the standard I/O messaging (Poll, COS, Cyclic) and explicit messaging services defined by the ODVA standard — including Omron, Mitsubishi, Siemens (via DeviceNet gateway), Beckhoff, and other third-party DeviceNet masters. The EDS file provided by SMC simplifies configuration in any compliant network configuration tool.

Q3: How does the EX160-SDN1A support remote diagnostics and fault tracing?The EX160-SDN1A maps valve coil short-circuit detection, open-load faults, and communication health status directly into the DeviceNet I/O data image. These diagnostic bits are readable by the PLC program and can be surfaced on HMI alarm pages or forwarded to SCADA alarm management systems. Remote engineers accessing the PLC via VPN can read these tags in real time, enabling fault identification and corrective action planning without requiring a site visit — reducing unplanned downtime and accelerating MTTR.

Q4: What warranty and pre-shipment testing does NANKMOS provide for the EX160-SDN1A?All EX160-SDN1A units supplied by NANKMOS are covered by a 12-month warranty against manufacturing defects from the date of shipment. Prior to dispatch, each unit undergoes functional verification including DeviceNet communication integrity testing, I/O mapping confirmation, and physical inspection of connectors and housing.
