Modular Controllers | Schneider Electric TSX3710128DTK1

The Schneider Electric TSX3710128DTK1 is a modular basic controller belonging to the Modicon TSX Micro automation platform. It serves as a compact processing unit featuring 16 discrete inputs and 12 solid-state discrete outputs, equipped with dual communication links and two expansion slots for flexible system configuration.

Controller Architecture and Processing Performance

The controller operates on a 24 V DC main voltage supply, with an input operating range of 19.2 to 30 V DC. It provides a micro-break resistance time of 10 ms to maintain operational stability during brief power dips.

Execution speed varies by instruction type, registering 0.25 µs for Boolean instructions and 4.81 µs for arithmetic REAL floating-point calculations when operating without an optional PCMCIA card. The internal memory configuration incorporates 14,000 words of internal RAM data and 15,000 words of flash data.

I/O Capacity and Communication Integration

The unit features an HE10 connector interface for its built-in discrete input/output section, comprising 16 discrete inputs at 24 V DC and 12 solid-state discrete outputs. Two integrated communication channels are provided: one serial link supporting Uni-Telway at 19.2 kbit/s and one Modbus port supporting Modbus RTU at 19.2 kbit/s.

Two expansion slots are available on the base controller for deploying additional application-specific or communication modules. An integrated real-time clock is included for accurate event time-stamping and scheduling tasks.

Application Structure and Execution

The application execution structure supports one master task, one fast task, and up to eight event tasks. The system overhead for the main master task is measured at 1.9 ms.

Object area memory allocations accommodate up to 256 internal bit objects (%Mi), 128 constant words (%KWi), and internal word registers (%MWi). Built-in protection mechanisms include overload protection and short-circuit protection for reliable field operation.
