Redundant in rack M580 Redundant Master modules?

Status: Under consideration Submitted by Lt. Commander Trinxs1 Lt. Commander on ‎2019-10-22 12:59 AM

How do you wish to implement redundant ERIO networks?

  1. Would you want a double ring topology?
    • Protocols - HSR, DLR, RSTP
    • Module - dual ring connections on single module, single ring connection on two modules
    • See Choice A
  2. Would you want a double network topology?
    • Protocol - PRP
    • Dual network with same information sent over both networks
    • More expense
    • See Choice B
  3. Would you want a separate backbone topology?
    • Protocol - up to installer
    • Dual connections to ethernet backbone managed by IT 
    • Third party protocols selected by user.
    • Must comply with basic requirements
    • See Choice C

Revised offer (2nd March 2020):

1. Single module with single connections to two separate ring / star  networks using PRP.

2.  Hot standby system with single connection for each CPU to two separate networks with two separate modules in each drop.

 

In each architecture PRP is primarily the network protocol.  The network is constructed using third party switches with some requirements to be specified in the design.

 

In the system proposed how many drops are required?

1. 32 drops

2. 64 drops

3.  more than this?  how many?

Currently the PME PXM 0100 module  supports the following 3 basic architectures:

-Standalone PLC – PXM in Local Rack

-Standalone PLC – PXM in Remote Rack

-HSBY PLC – PXMs in Local Rack

 

For future development our work with ProSoft will take into account the PXM additional redundancy modes enhancement listed below and we need your feedback to know the business case of these new functionalities.

 

Could you send me your feedback (Customer name, architecture targeted, PXM & CPU number targeted with these new functionalities)?

 

The table below summarizes the various configurations, (both existing and proposed)

A and B have my preference.

I think PRP is on the winning hand, but a solution without extra switches is not bad eather.

I have few question on PRP feature

1. Which PLC supports PRP protocol?

2. in the choice B(PRP), M580 NOC module generates PRP packets? If yes, which module support PRP?

3. I have Modbus TCP device which supports PRP. How to test PRP feature with Modicon PLC?

My apologies I have been away for a few weeks.

1.  M580 in a release later in 2024 or possibly 2025 schneider will have modules that support PRP.  This is part of the dual redundant ethernet remote IO network.  It will occur in stages but the first will provide drop modules in the rack that support PRP and at the CPU end there may be third party modules and eventually M580 PRP modules that sit in the rack.

2.  The BMENOC module at this stage will not support PRP.  The intent for PRP is to effectively provide zero communications down time between the M580 CPU and the remote IO X80 racks.  It may be a feature in the future if there is sufficient demand but this need must be made known to your Schneider account managers and technical support people so we can try to drive the road map of development.

3.   The PRP modules will allow other protocols to co-exist.  Its aim is to ensure that two sets of the same ethernet packet are sent to each destination and at the destination the recipient rejects duplicated packages.  To test you would need to monitor the update rate of the messages at the modules.  Typically, this should be the same irrespective if both or one of the network pathways is operational. 
To test break a network to see if the update rate changes. I am deliberately vague at the moment as the equipment has not been released, I cannot provide exact details. 

4.  At the CPU end we will have the start of the PRP network.  Initially this will be with a Hirschmann RED25 - which provides RSTP to PRP (Port PRP-A and port PRP-B) at the other end of the communication i.e. the drop racks there will be a new full length CRA module which will also have (Port PRP-A and port PRP-B).  If the system is a hot standby CPU system, it may also be possible to have two new PRP CRA modules in one drop rack.  In this case one module will be the primary module and the other will be a standby module.

Field testing for the dual ethernet remote io network system will commence in 2023.
