IEC 870

Colleagues I need to provide IEC 870 support for an RTU so that it can communicate with intelligent electronic devices supporting IEC 870 protocol over a serial , radio or telephione line. Please forward any information on companies that provide (1) IEC 870 source code library. (2) Contract IEC 870 protocol development. (3) Intelligent electronic devices that support IEC 870. (4) IEC 870 protocol support for the OS/9 operating system. Regards Pat Conway.

RE: IEC 870

I assume that you are interested in one of the following: 870-5-101 ( IEC based standard for RTUs) or 870-5-103 ( IEC based standard for Protection Relays) or DNP V3.00 ( Almost conforms to parts of IEC 870-5-1/870-5-2) (1) Don't know of any for the IEC870-5-101 and 103 but one does exist for DNP V3.00. (2) See below for self promotion. (3) DNP 3.00 is widely supported, especially in the US and increasingly in Australia. Contact the DNP Users group for more information (they do have a WEB site). More vendors are implemention 870-5-101 - it seems to be more popular in Europe. 870-5-103 is main for protection equipment and I think Siemens are using it. (4) Don't know. I work for Sinclair Knight Merz in Perth, Western Australia. We are currently nearing completion of a IEC870-5-101 emulation and are familiar with DNP V3.00. Please contact me directly if you do require programming services. Best regards

RE: IEC 870 Source Code Library

Triangle MicroWorks provides ANSI standard "C" Source Code Libraries for IEC 870-5 and other popular communication protocols such as DNP. The literature for the Libraries contains many diagrams, so it is best sent by fax, with originals to follow in the mail. See contact information below. We also offer on-site consulting services to assist your engineers or complete project development to integrate our source code libraries into your product. I am not aware of a list of manufacturers of IEC 870-5 equipment similar to that provided for DNP on the DNP Users Group Web Page (www.dnp.org). Triangle MicroWorks will create such a list on our web page containing any IEC 870-5 equipment manufacturers that send us information. While we do not have any software specifically designed for the OS/9 operating system, our communication protocol libraries are designed to work with or without Real Time Operating System support. Therefore, I do not foresee any problem modifying the 3 platform specific source code files to run in the OS/9 environment. Please send me your fax number and mailing address for more information. Regards Jim

Re: IEC-870-5-101 and IEC-870-5-103

---------------------------------------------------------------------------------- To Paul Whitfield I used twice this "plug in" drivers: The first one, we bought a VBX driver, from a Driver seller, to GE-Fanuc Genius protocol. We adapted this driver in our SCADA system in one day and it works very well to our aplication case; The second one, was a DDE driver, used with Intouch SCADA, to a ethernet GE-Fanuc protocol and it's working, but we are yet comissioning the system, and I can't say, at this time, that every thing is working well, once we didn't conclude all tests. The advantage to use this "plug in" drivers, in my point of view, is the time you spend to implement the driver. More than this, I consider that OCX and Ole server drivers are more efficient than DDE drivers. Concluding this sunject, we are used to put a front-end-processor when we implement a system with a lot of points conected via radio or serial line comunication and the Windows-NT driver it's connected to this front-end (by LAN or serial line). --------------------------------------------------------------------------------- Returning to my problem, that is looking for drivers to IEC-870-5-101 and IEC-870-5-103. My problem is that we are working in two systems: 1) The automation of a power eletrical substation that has AEG numerical relays (Ps 421/431/441, PM481, PQ721, PD531/571 and STF10/20/30). This relay, according the folks from AEG-Brasil, have the IEC-870-5-103 protocol and we need to implement a gateway to connect them to our system. I supouse the way to do this is to buy or develop a IEC-870-5-103 driver. Some one has another solution? 2)- The automation of a Regional Center that will be connected to several power eletric substations that have a IEC-870-5-101 protocol implemented by Siemens, to implement the comunication with the SCADA regional center. Again, we are looking for a solution less expensive than develop this drivers. Best Regard Simões (spin@tba.com.br)
