Introduction
Application Relationship. PROFINET term for a relationship that is established
between an IO-Controller/Supervisor and IO-Device. For any data to be
exchanged between an IO-Controller/Supervisor and a given IO-Device, an
Application Relationship must be established. Within the Application
Relationship, various Communication Relationships (CRs) are then
established for the different types of data to be exchanged.
In Ethernet, the transmission of a network message to all hosts on the
network.
Command Line Interface
In a PACSystems RX3i PROFINET network, a CPU Node is a node in which a
PACSystems RX3i CPU is connected to the PROFINET network.
Communication Relationship. PROFINET term for a channel that is
established within an Application Relationship (AR) to transfer specific data
between an IO-Controller/Supervisor and a given IO-Device. Multiple CRs are
established within an AR to transfer data.
An Ethernet port connection on the PROFINET I/O Controller that is
configured as a critical port. When the last Critical Network Port is
disconnected from its network, a diagnostic fault is logged. In a redundancy
system where the PROFINET I/O Controller is controlling redundant devices,
this results in a CPU redundancy role-switch with the CPU placed into
Stop/Fault mode.
Device Access Point. This access point is used to address an IO-Device as an
entity.
An Address Resolution Protocol (ARP) request sent by the host to resolve its
own IP Address.
