Yokogawa AAR145-S00/S1: Industrial Data Link for Centum VP Smart Factory Networks
The Yokogawa AAR145-S00/S1 is a high-precision 16-channel RTD input module engineered for seamless integration within the Centum VP Distributed Control System (DCS) architecture. Operating over the Vnet/IP real-time industrial Ethernet protocol, this module serves as a critical node in the plant-wide data acquisition chain — bridging field-level temperature sensors directly into the supervisory control and SCADA layers with deterministic, low-latency signal transmission.
In modern smart factory environments, the integrity of the data link between field instruments and upper-level control systems defines the reliability of the entire production process. The AAR145-S00/S1 addresses this requirement by delivering continuous, high-fidelity RTD measurements — supporting Pt100, Pt200, Pt500, Pt1000, Cu10, Ni100, and other resistance thermometer types — directly into the Centum VP controller bus. This eliminates signal conversion bottlenecks and ensures that process variables are available to the Centum VP HIS (Human Interface Station) and connected SCADA platforms in real time.

Connected Automation Data Flow
The AAR145-S00/S1 sits at the foundation of the plant data acquisition layer. Temperature signals from field-mounted RTD sensors — such as those wired into Yokogawa’s EJA110E differential pressure transmitters or standalone Pt100 probes — are conditioned and digitized within the module before being transmitted upstream via the Vnet/IP ring network. This ring topology, shared with other I/O modules such as the AAI143-S analog input module and the AAI841-S analog output module, ensures that a single cable fault does not interrupt data flow to the Centum VP FCS (Field Control Station).
Within the FCS, the digitized RTD values are processed by the Centum VP ACF11D or ACF12D field control units, where control logic — PID loops, cascade control, and interlock sequences — operates on the live temperature data. The processed control outputs are then distributed to actuators and drives via output modules, while the raw and processed data streams are simultaneously forwarded over the plant Ethernet backbone to the Centum VP HIS operator stations running CENTUM VP R6 software.
For facilities integrating third-party SCADA platforms such as Wonderware, Ignition, or OSIsoft PI, the Vnet/IP data is bridged through the Yokogawa Exaopc OPC DA/UA server, enabling seamless historian integration and real-time KPI dashboards. Remote I/O extensions using Yokogawa RIO (Remote I/O) nodes can further expand the measurement network across geographically distributed process areas without additional protocol conversion overhead. Edge computing gateways connected to the Centum VP network can also subscribe to AAR145-S00/S1 data streams for AI-driven predictive maintenance and anomaly detection workflows.
Solving Data Isolation in Industrial Sites
One of the most persistent challenges in legacy and hybrid industrial facilities is the fragmentation of process data across incompatible protocols and isolated control islands. The AAR145-S00/S1, as a native Vnet/IP module, eliminates the need for external protocol converters or signal repeaters between the RTD field layer and the Centum VP control network. This direct integration ensures that temperature data from every monitored point — whether in a reactor vessel, heat exchanger, distillation column, or pipeline — is immediately available to operators, engineers, and remote monitoring systems without latency introduced by gateway translation.
For plants running mixed automation environments, the Centum VP’s open connectivity through OPC UA and Modbus TCP allows the AAR145-S00/S1’s data to be shared with third-party PLCs, MES platforms, and ERP systems, breaking down data silos that traditionally prevented production transparency. Remote diagnostic capabilities built into the Centum VP architecture allow maintenance engineers to interrogate module health, channel status, and wire-break alarms from the HIS or from remote workstations — reducing unplanned downtime and enabling condition-based maintenance strategies. As production lines expand, additional AAR145-S00/S1 modules can be added to existing I/O nests without system shutdown, supporting scalable, non-disruptive capacity growth.
Industrial Connectivity FAQ
Q1: What communication protocol does the AAR145-S00/S1 use, and is it compatible with third-party SCADA systems?
The AAR145-S00/S1 communicates natively over Vnet/IP, Yokogawa’s proprietary real-time industrial Ethernet protocol used within the Centum VP DCS. For integration with third-party SCADA platforms, data is exposed via the Yokogawa Exaopc OPC DA/UA server, providing broad compatibility with Wonderware, Ignition, OSIsoft PI, and other industry-standard SCADA and historian systems.
Q2: How does the module ensure network stability and data integrity in demanding plant environments?
The Vnet/IP ring topology provides built-in redundancy — if one segment of the communication ring is interrupted, data automatically reroutes through the alternate path within milliseconds, ensuring continuous process visibility. Channel-to-channel and channel-to-bus isolation further protects signal integrity against electrical noise common in industrial environments.
Q3: Can the AAR145-S00/S1 be added to an existing Centum VP system without shutting down production?
Yes. The Centum VP I/O architecture supports online module insertion into compatible ANB10D and ANT1D nests. New AAR145-S00/S1 modules can be configured and brought online while the system remains in operation, enabling non-disruptive system expansion and capacity upgrades.
Q4: What quality assurance and warranty coverage is provided with this module?
Every AAR145-S00/S1 unit supplied by ZYPLC undergoes functional testing prior to shipment, verifying communication integrity, channel accuracy, and protocol handshake with the Centum VP system. A 12-month warranty is included, covering hardware defects and communication failures. Our technical team provides pre-sales configuration support and post-sales remote diagnostic assistance.
