IEC 60870, 60850 and 62541, OPC UA protocol support?

[Peter Valdemar Mørch]

Hi,

I'm a little new to SCADA. A customer of ours wants us to "receive alarms" from SCADA equipment. He says IEC 60870 is the "old" standard, and these are the new standards: IEC 61850, IEC 62541 and OPC UA. And that all his equipment will communicate with these protocols.

The Wikipedia entry for SCADA also mentions (some of) these protocols, but I've found no mention of them in the openSCADA home page, in the wiki, this group or other places.

I'm hoping to find a high-quality open source library that runs on Linux and allows communication with SCADA products using these protocols so we can monitor SCADA equipment and keep status current in a network management system.

Will openSCADA be able to help here? Are there any other open source products you can recommend? If not, what proprietary solutions could we consider?

Is there some fundamental misunderstanding I'm suffering from? I'm surprised that these protocols seem to be most popular standard SCADA protocols, but a project called openSCADA doesn't even mention them...

Thanks for any pointers or help.

Sincerely,

Peter

Hi Peter,

That is the problem with standards. Some of them are not even standards at all (like OPC) and some others are not widely used.

OpenSCADA supports what was actually needed. The protocols you mentioned never were up to now. OPC DA 2.0 is actually widely used and supported by openSCADA.

OpenSCADA supports a driver framework to write your own drivers and provides a platform to integrate them. So if you need something you can write it yourself or ask someone to write it for you.

Best regards

Jens Reimann

hi,

what I know is that there is great interest (specially in Energy utilities) to foster 61850 as standard.

but indeed we see a lot of 60870, dnp3 and OPC-DA2.0 around, in practical sense.

as for open-source libraries, I recommend you google "openMUC" or open61850 for that specific standard.

maybe you could be successfull integrating that to OpenSCADA?

we have preliminary work towards using openMUC in ScadaBR which was spun-off from mango,

but we work on a very loose schedule (no strict milestones yet).

hope that helps

OPC UA is a standard: IEC 62541.  IEC 62541 is being submitted to IEC TC 57 (the committee responsible for IEC 61850) as a candidate for the IEC 61850 Web Service Profile.

[John Gillerman]

There are open source libraries that you can use to create an OPC UA (IEC 62541) client.  You can use an OPC DA to UA wrapper with an IEC 61850 client to get convert IEC 61850 Reports into OPC UA events.

Hi Peter,

did you evolve around this issue?

has our info been valuable?

i am big fan of openScada and i´m sure it will get always better.

SCADA is highly specialized business. 

I mean, if you are somewhat new, you should study very well --- or look for professional paid support, even if you choose open-source software... that may still be cheaper than buying commercial off-the-shelf SCADA software (like ABB, siemens, schneider, GE etc.)

i am doing SCADA for around 10 years now and am always surprised with all those protocols. maybe you should not loook to support 100% of them protocols, but rather  stick to 2~3 most used, and use gateways (hw or sw converters) as needed.

 60870, dnp3, da2.0 and MODBUS will be excellent choices for yet another many years i guess.

 they have been around for decades, and SCADA people in the market are still very conservative. 

even those fancy 61850 will have some legacy 60870 or modbus embedded to them, you could bet :-)

best luck

Victor
