Introduction

The advanced diagnostics for redundant power supplies use a specific protocol for power supplies installed in a main rack with an Ethernet backplane.

These function blocks are used for redundant power supplies that are located:

• Within a Modicon M580 configuration.

• In a main rack. Therefore they do not apply to power supplies located in an extension rack (using a BMXXBE•••• extender module).

• In a dedicated BMEXBP••02 rack.
