M580 HSBY High-Capacity Daisy Chain Loop (HCDL)

[TheLegendTMX]

Dears,

We have a redundant M580 HSBY system divided into two separate, distant, and identical locations that should serve as one system.

Each location contains:

• One CPU
• Two RIO drops
• Two main network switches of the following type:
  "SGS-6310-48P6XR," Planet L3 48-Port 10/100/1000T 802.3at PoE + 6-Port 10G SFP+ Stackable Managed Switch

The available fiber link between the two locations is designated for:

1. Linking the main network switches in a ring.
2. Linking the two CPUs via the SFP HSBY connection.

Referring to the Modicon M580 Complex Topologies System Guide, Page 177, we need your recommendations for implementing the High-Capacity Daisy Chain Loop (HCDL) architecture in this M580 HSBY system.

We are considering establishing a dedicated VLAN on the main network switches to isolate HCDL traffic from other network traffic.

Question:
Is there anything specific to consider within the main switches or the M580 HSBY configuration for this setup?

Your advice and insights will be greatly appreciated.

Thank you in advance!

Hello TheLegendTMX,

It would be convenient if you shared in a schematic form the architecture that you propose, so that we can get an idea of ​​what you are proposing.
Just remember that the HSBY Link must be a dedicated point-to-point connection without elements between CPUs.

The architectures proposed in the document you mention are validated with Schneider Dual Ring equipment. If you want to use other Switch devices, I would recommend consulting your country's technical support as it requires a thorough analysis of the entire architecture.

I would advise you to review the following manual
