Connect AC800M controller (CI855) to faraway network switch

Dear,

Could you please help me with this issue:

I have one AC70 connecting to AC450 thru Advant Filedbus 100 (hard wire). That wire is underground with long distance. Now I want to upgrade AC70 with AF100 to AC800M with MB300 (current Control Network of AC450) Interface module CI855.
The issue is there any way to take advantage of existing hard wire to connect AC800M(CI855) to MB300 network switch? I don't have route for Fiber optics.

Thank you in advance.

Vu,

Hello Vu
can't you use AF100 with new AC800M+CI869 in place of AC70? In this case you don't have to worry about whether communication will work or not.

Note that MB300 is not based on TCP/IP, it works via UDP ethernet protocol and it is not easy to find a reliable ethernet switch which works with MB300.

If you really need to use MB300 then *maybe* you can think about using pair of ethernet extenders via RS485.
The first one I have googled is PATTON CL1101/TB.
For me this solution is more curiosity than reliable one. You should definitely test it before you go ahead.

Thanks so much, kamil.
Your suggestion CI869 is good for me to think about.
In addition, about "it is not easy to find a reliable ethernet switch which works with MB300.", I also intend to replace my MB300 switch (Unmanaged HISCHMANN switch) by more ports, Managed HIRSCHMANN switch.
Can you advise me some kinds?

Thank you,
Vu,

I have seen Hirschmann switches connected in FO ring working as MB300 network. Hirschmann managed switch should work. Avoid Cisco for MB300.
Also consider using conversion tool Ampl2m dot com, which i developed for logic conversion to AC800M. I have used it many times successfully.

Many thanks, kamil.
I've known about Ampl2m tool which you developed, but not have chance to use it.
This may be the big chance.

MB300 is based on IEEE 802.3 in other words Ethernet!

i dare to write that any Ethernet switch or hub will work with MB300.

AF100 is not Ethernet

There are devices that can sustain Ethernet bridging over twisted pair, eg Westermo Wolverine: https://www.westermo.se/products/ethernet-extenders/managed/ddw-142

Fantastic, Stefan.
This is what I've been finding recent days.
Thanks so much for your advice and info.

Good. Once you've been able to wire up Ethernet and managed to "ping", etc. over to the "other side" (e.g. the management interface of said Westermo should be a possible ping target) you could think of having MB300 going the same way.

Ethernet Multicast *must* be enabled (its butter & bread to MB300 and RNRP). I mention this because Westermo has IGMP enabled by default and it needs to be disabled. Please make sure multicast is possible before you make a purchase of hardware.

MB300 E (extended) is also an option in case bandwidth is low; selecting E enables you to slow down the pace of routing messages, etc. and "buy" more bandbread for your application and slowing down the supervision of the link.

In addition: MB300 is fully IEEE 802.3 compliant! If the switch is not working with MB300 there is something wrong with the switch!
I do not agree with Mr Herman's statement regarding MB300.
As far as possible ABB recommend the ABB Branded switches for MB300 today, i.e NE801, NE802, NE810, NE820 & NE840. They are tested and certified for MB300 and 800xA

In addition, as VU already have AF100 communication with his AC70, why not just replace the AC70 with AC800M with CI869 and reuse the AF100 ? There AF100 do also have a much higher performance, you my run DSP dataset dow to 16 ms or so if needed. MB300 fastest DS is 0.5 s . ABB take no responsibility for wolverine converters from to MB300 via twisted pair, and that concept. it is at your own risk.

Likely my statement "it is not easy to find ethernet switch working with MB300" was too much expressive. The motivation for the post was I faced several times situation that some switch refused to work with MB300 properly. The last case was with Cisco manageable switch delivered by customer. IT specialist spent 1 day then tweaking settings to open Cisco for MB300. The issue was AC450 response time to Online builder commands was too long.
