Schneider Multi-Function Programming Cable TSXPCX1031-C for Schneider TWIDO/NEZA series TSXPCX1031C

TSXPCX1031-C | Schneider Electric RS232 Connecting Cable — 2.5m / DTE Terminal Port / Modicon / TSX Micro / Twido / Magelis

RS232 Connecting Cable for Schneider Electric PLC and HMI Platforms

The TSXPCX1031-C is Schneider Electric's RS232 connecting cable for the DTE (Data Terminal Equipment) terminal port — the standard programming and communication cable bridging a PC or laptop serial port to Schneider Electric's range of compact controllers and HMI terminals.

The cable connects the controller's serial terminal port to the PC's COM port, enabling the PLC programming software to upload, download, and monitor programmes on the target controller. A single cable serves multiple Schneider Electric controller families, making it a versatile accessory for engineers maintaining or commissioning installations across the Modicon and Harmony product ranges.

Key Specifications

Connector Configuration — Two Interfaces, One Cable

The TSXPCX1031-C uses a dual-connector approach to serve different controller interface types:

8-pin mini DIN female: Connects to the DIN8 TER/AUX programming port on TSX Micro, Twido, and related controllers. Mini DIN is compact and locks positively — suited to the small form factor of these controller families.

D-Sub DE-09 female (DB9): Connects to the standard RS232 COM port on a PC or laptop. The DE-09 male on the PC mates with this female connector on the cable.

Included 9-to-25 pin adapter: Adds compatibility with older PC COM ports using the larger DB25 connector — extending the cable's usefulness to legacy workstations and industrial computers that retain the 25-pin format

Applications

PLC commissioning: Connecting a programming laptop to a Modicon Premium or TSX Micro controller on a new machine installation — downloading the initial programme, configuring parameters, and verifying I/O operation.

On-site fault diagnosis: Maintenance engineers connecting to installed Twido or TSX Micro controllers for online ladder diagram monitoring, checking input/output status, and diagnosing faults.

HMI configuration: Uploading completed screen configurations from a PC to Magelis XBT operator terminals on production machines, conveyor systems, and packaging equipment.

Programme backup: Uploading programmes from installed Modicon Premium or TSX Micro controllers to PC storage — creating programme backups before maintenance work or drive replacements.

FAQ

Q1: Does TSXPCX1031-C work as a USB cable or does it require a physical DB9 COM port?

The TSXPCX1031-C is a DB9 RS232 cable — it requires a physical 9-pin COM port on the PC. For laptops and modern PCs without a DB9 COM port, a separate USB-to-RS232 adapter (such as a FTDI-based adapter) is required. Confirm USB-to-RS232 adapter compatibility with the Schneider Electric programming software in use.

Q2: What programming software works with TSXPCX1031-C for TSX Micro and Modicon Premium?

PL7 Pro (for TSX Premium and TSX Micro) and TwidoSoft/TwidoSuite (for Twido controllers) are the standard programming environments for these controller families. Both use the TSXPCX1031-C cable for serial connection. Unity Pro and EcoStruxure Control Expert support later Modicon platforms — confirm the software version matches the controller type being programmed.

Q3: Can TSXPCX1031-C be used for Modbus RTU communication monitoring as well as programming?

Yes — the RS485 capability of the TSXPCX1031-C allows it to be used for connecting to Modbus RTU serial networks at the controller's TER/AUX port. Depending on the controller configuration, this enables both programming access and Modbus master/slave communication monitoring through the same physical cable interface.

Q4: What is the difference between TSXPCX1031 and TSXPCX1031-C?

The base TSXPCX1031 and its "-C" variant share the same electrical specifications, connector types, and compatible platform list. The "-C" suffix identifies a specific product variant in Schneider Electric's ordering system — typically indicating a regional certification, packaging, or configuration difference. Both serve the same functional role: RS232/RS485 connecting cable for Schneider Electric DTE terminal ports.
