Schneider Electric 08747900 Communication Cable

Product Details

08747900 Product Description

The Schneider Electric 08747900 is a dedicated PMP (Programming and Monitoring Port) communication cable engineered for TeSys T motor management controllers. Designed to bridge the gap between field-level motor protection devices and upper-layer automation systems, this cable enables seamless data exchange across Modbus RTU and DeviceNet industrial networks. In modern smart factory environments where every motor, drive, and protection relay must be visible, controllable, and diagnosable from a central SCADA or HMI platform, the 08747900 serves as a critical physical link in the industrial data chain.

In a fully connected smart factory, the 08747900 cable initiates the data journey at the motor protection layer. The TeSys T LTM R motor management controller — connected via this PMP cable — captures real-time electrical parameters including current, voltage, power factor, thermal state, and fault codes directly from the motor circuit. This data is then transmitted upstream through a Modbus RTU or DeviceNet network segment to a Modicon M340 or Modicon M580 PLC, where logic controllers process protection thresholds and interlock conditions.

From the PLC layer, process data flows into a Vijeo Designer or EcoStruxure Operator Terminal HMI panel, giving operators a live dashboard of motor health, running hours, and alarm states. Simultaneously, the Modbus TCP/IP gateway — such as a Schneider Electric BMXNOE0110 Ethernet communication module — bridges the field-level Modbus RTU segment to the plant's Ethernet backbone, enabling SCADA systems like EcoStruxure SCADA Expert (formerly Vijeo Citect) to aggregate motor data from dozens of TeSys T nodes across the production floor.

At the edge layer, an industrial edge gateway running EcoStruxure Machine Advisor or a third-party IIoT platform collects time-series motor data — start/stop cycles, overload events, phase imbalance trends — and pushes it to cloud analytics dashboards. This enables predictive maintenance workflows: when the TeSys T detects a rising thermal trend or repeated overcurrent trips, an automated alarm is generated in the SCADA system, a notification is pushed to the maintenance team's mobile device, and a work order is logged in the CMMS — all without manual intervention.

The 08747900 cable also supports direct PC-based configuration via Schneider Electric's SoMove software, allowing engineers to set motor protection parameters, configure communication addresses, and run diagnostic routines without disconnecting the device from the live network. This is particularly valuable during commissioning of new production lines or when integrating TeSys T units into existing Modicon-based control architectures alongside Altivar ATV320 or ATV630 variable frequency drives, which share the same Modbus RTU segment and report drive status — speed reference, output frequency, fault codes — to the same SCADA historian.

Remote I/O modules such as the Schneider Electric TM3 expansion modules extend the data reach further, feeding digital and analog signals from sensors, pressure transmitters, and flow meters into the same Modbus network. Industrial managed switches — for example, the ConneXium TCSESM series — provide the Ethernet switching fabric that ties together the PLC, HMI, SCADA server, and edge gateway into a single, resilient industrial LAN. The result is a complete, end-to-end data pipeline: from the motor terminal block, through the TeSys T and 08747900 cable, across the Modbus fieldbus, through the PLC and gateway, and up to the enterprise MES or ERP system.

Protocol Fragmentation: Many legacy motor control centers rely on hardwired I/O with no digital communication. The 08747900 cable enables TeSys T controllers to participate in Modbus RTU and DeviceNet networks, eliminating the protocol gap between motor protection relays and modern PLC/SCADA systems without requiring hardware replacement of the motor starter itself.

Data Silos and Production Transparency: Without a communication-capable motor controller, motor health data remains invisible to the control room. The 08747900 unlocks real-time visibility into motor current, thermal load, and fault history, feeding this data into SCADA historians and enabling production line transparency — operators can see exactly which motor is running, at what load, and how close it is to a thermal trip.

Remote Monitoring and Diagnostics: Field engineers no longer need to walk the plant floor to check motor status. With the 08747900 connecting TeSys T to the Modbus network, all motor parameters are accessible remotely from the SCADA workstation or via EcoStruxure Machine Advisor's cloud dashboard. Fault codes, trip history, and thermal curves can be reviewed and analyzed without physical access to the motor control panel.

Alarm Tracking and Response: Unstructured alarm floods are a common problem in large automation sites. By integrating TeSys T motor data into the SCADA alarm management system via the 08747900 cable, each motor fault generates a structured, timestamped alarm event with cause code and affected circuit ID — enabling faster root cause analysis and reducing mean time to repair (MTTR).

System Scalability: As production capacity grows, additional TeSys T motor controllers can be added to the existing Modbus RTU segment using the same 08747900 cable type, with each new node assigned a unique Modbus address. The network scales without requiring new communication infrastructure, making the 08747900 a cost-effective connectivity solution for phased factory expansion projects.

Q1: Does the 08747900 cable support both Modbus RTU and DeviceNet simultaneously? The 08747900 is a PMP port cable that connects to the TeSys T controller's programming and monitoring port. The TeSys T LTM R supports Modbus RTU and DeviceNet as separate network options depending on the communication module fitted. The 08747900 cable is used for direct PC connection via SoMove software or for daisy-chaining multiple TeSys T units on a Modbus RTU segment. Confirm your TeSys T communication module variant (LTM9CU•• for Modbus, LTM9CD•• for DeviceNet) to ensure protocol compatibility.

Q2: What is the maximum network segment length and node count for a Modbus RTU installation using TeSys T with this cable? Modbus RTU over RS-485 supports up to 247 addressable nodes and cable runs of up to 1,200 meters at 9,600 baud. In practice, TeSys T installations typically use baud rates of 19,200 or 38,400 bps with appropriate termination resistors at each end of the segment. The 08747900 cable connects the TeSys T PMP port to the RS-485 network adapter or directly to a PC COM port for configuration — network length limits apply to the RS-485 backbone, not the PMP cable itself.

Q3: Can the 08747900 be used for remote diagnostics while the motor is running under load? Yes. The TeSys T controller supports live parameter monitoring via the PMP port without interrupting motor operation. Using SoMove software connected via the 08747900 cable, engineers can read real-time current, voltage, power factor, thermal capacity used, and fault history while the motor runs at full load. This non-intrusive diagnostic capability is essential for condition monitoring and predictive maintenance programs in continuous-process industries.

Q4: What warranty and pre-shipment testing does NANKMOS provide for the 08747900? All Schneider Electric 08747900 cables supplied by NANKMOS carry a 12-month warranty covering manufacturing defects and functional failures under normal operating conditions. Each unit undergoes pre-shipment functional verification to confirm connector integrity and cable continuity before dispatch. In-stock units are available for same-week global shipping.
