Those who have been involved in utilizing ethernet and other non-failsafe networking systems in industrial environments know that there should always be a second independent parallel hardware circuit for safety reasons. It seems that that time has passed. B&R announced a new open safety protocol to be used in real-time Ethernet applications.

The ETHERNET Powerlink Safety Technology or EPL Safety technology allows a standard fieldbus network to carry both normal control and safety signals. The EPL technology conforms to IEC 61508 SIL Cat3.

More information at the company website.

Seems like a nice development. You are mentioning that it is working for a standard fieldbus network. Does this mean I can use the epl safety technology also with modbus? I am currently developing a modbus application and would like to know.

Thanks,
Bob

I have checked your question with B&R and the EPL Safety Technology is independent of the transport protocol. This means that the technology can be used on all current fieldbus systems, including Modbus. The problem is, that B&R has to provide the details of the protocol to make it possible to implement it on other fieldbus structures and if and when this will happen is a question. At this moment their priority certainly lies on promoting and selling their own products with the EPL safety technology, rather than making it available for competitors.

You might however take a look at Hima. They manufacture safety solutions, including safety applications over Modbus. I have no idea about pricing--they seem to operate in the high-end market--but looking at their products and services, they should be able to provide a Modbus safety solution for your situation.
