Introduction

A copper cable connection between two consecutive RIO drops cannot exceed 100 m. A fiber cable connection between two consecutive RIO drops cannot exceed 15 km (single mode) or 2.5 km (multi-mode).

For more information, refer to chapter Modicon X80 Racks Installation and Electrical installation guide.

Connections Between Devices

This figure shows the distances between RIO drops in a high-capacity daisy chain loop:

1 main local rack

2 copper cable (twisted pair)

3 RIO drop

4 DRSs (with copper and optic fiber ports): This DRS extends the distance between devices using fiber optic cable (up to 15 km).

5 fiber optic cable

6 RIO drop with a BMXNRP0200 fiber converter module
