Abstract
In an automation system, a protocol converter is provided between a first network and a second network for converting safety-related messages between the first and second networks that use different network protocols for message exchange. In the protocol converter, a single-channel filter connected to a single-channel interface determines messages having a first safety communication protocol from messages received from the interface over the first network and messages having a second safety communication protocol received over the second network. An at least dual-channel safety module connected to the single-channel filter then converts the messages with the first safety communication protocol determined by the single-channel filter into messages with the second safety communication protocol, or converts the messages with the second safety communication protocol determined by the single-channel filter into messages with the first safety communication protocol.
