■Listen Only (originator)
This application type is for Exclusive Owner and Input Only, allowing only data receiving through multicast in the direction from
the target where a multicast connection is already open to the CC-Link IE TSN Plus module (originator).
A connection cannot be opened for an external device where a connection through multicast is not open.
If all multicast connections for which the application type for the target is not set to Listen Only are disconnected, even if
connections opened by using Listen Only are normal, the target stops data sending.
