PLC Backplane Communication and I/O Architecture

The TSX3708056DR1 provides a modular PLC base structure with three expansion slots and integrated discrete I/O processing. The controller executes one master task, one fast task, and up to eight event tasks. Internal memory allocation includes RAM data storage and Flash data storage for application handling.

The controller supports deterministic serial communication through Uni-Telway and Modbus RTU links at 19.2 kbit/s. Its I/O density configuration includes 32 24 VDC discrete inputs and 24 relay outputs connected through screw terminal interfaces.

For Schneider Electric PLC platforms, firmware flash compatibility and backplane bus communication define module integration behavior within the TSX Micro architecture. Expansion modules must match the supported TSX Micro hardware configuration and communication addressing structure.

Frequently Asked Questions

Q: What type of I/O is integrated into the TSX3708056DR1 controller?
A: The controller contains 32 discrete 24 VDC inputs and 24 relay outputs through a screw terminal discrete I/O interface.

Q: Which communication protocols are available on the TSX3708056DR1?
A: The controller provides one Uni-Telway serial communication link and one Modbus RTU serial communication link, both operating at 19.2 kbit/s.

Q: Can the TSX3708056DR1 operate with modern Modicon PLC expansion systems?
A: The TSX3708056DR1 belongs to the discontinued Modicon TSX Micro platform. Compatibility depends on the existing TSX Micro hardware architecture and supported replacement solutions.

Field Installation Guidelines

Install the TSX3708056DR1 in accordance with the Modicon TSX Micro hardware installation requirements. Verify the power supply range before connection and maintain separation between AC power wiring, relay output circuits, and low-level communication cables.

Use proper grounding practices for the PLC chassis and communication cable shields. Serial communication wiring should follow the recommended cable routing method to reduce electromagnetic interference. Confirm terminal tightening, module seating, and I/O addressing before system commissioning.

The controller was discontinued on Dec 31, 2019 and reached end-of-service status on Jan 22, 2021. No direct replacement was specified by Schneider Electric.
