FAQ

Question?

What is the main purpose of the TSXRKY4EX rack?

Answer:

The TSXRKY4EX serves as an extension backplane for a Schneider TSX Premium PLC system. It allows you to add four more modules to your system when the main rack is full, connecting back to the CPU via a bus extension cable.

Question?

Is the TSXRKY4EX compatible with the new Modicon M580 series modules?

Answer:

No, this rack is specifically designed for the older TSX Premium series. It is not electrically or mechanically compatible with the modern Modicon M340 or M580 modules.

Question?

How is the rack address set on the TSXRKY4EX for a multi-rack configuration?

Answer:

The rack address is set using the small rotary switches or DIP switches located on the front of the unit, labeled ‘Rack Address’. Each rack in the system must have a unique address for the CPU to correctly identify and communicate with it, as indicated by the orange warning label.
