Directed ADS communication

The configuration of a directed ADS communication takes place using the checkbox Unidirectional when creating the route.

If this checkbox is set, TwinCAT will not accept any ADS command calls from the opposite target system via the associated route. TwinCAT itself sends ADS command calls (requests) and receives responses.

In the XML configuration this setting is made via the attribute Unidirectional="true":

    <RemoteConnections>
        <Route Unidirectional="true">
            <Name>CX-123456</Name>
            <Address>CX-123456</Address>
            <NetId>5.36.69.176.1.1</NetId>
            <Type>TCP_IP</Type>
            <Flags>128</Flags>
            <Tls>
            …
            </Tls>
        </Route>
    </RemoteConnections>
