            Description

            In the case where at least one CIP class 0/1 InputOnly connection is opened with the device, but no Exlusive Owner Connections, the Identity Object Attribute 5 reflected "no I/O connections established" as the Extended Device Status. This has been changed.

            Now, in this particular case, the Extended Device Status will be set to "at least one I/O connection established, all in IDLE mode".

            Note that, per definition, a InputOnly/ListenOnly connection cannot set a RUN status in the device. Hence the InputOnly/ListenOnly is always classified as an IDLE mode connection here.

             

            According to CIP Volume 1 an I/O connection is defined as:

                  Activity
