Chapter 4 Communicate over Networks
These software products are available for EtherNet/IP networks.
Producing and Consuming Data via an EtherNet/IP Network
The controller supports the ability to produce (send) and consume (receive) tags
over an EtherNet/IP network. Produced and consumed tags each require
connections. The total number of tags that can be produced or consumed is
limited by the number of available connections.
Connections over the EtherNet/IP Network
You indirectly determine the number of connections the safety controller uses by
configuring the controller to communicate with other devices in the system.
Connections are allocations of resources that provide more reliable
communication between devices compared to unconnected messages (message
instructions).
EtherNet/IP connections are unscheduled. An unscheduled connection is
triggered by the requested packet interval (RPI) for I/O control or the program
(such as a MSG instruction). Unscheduled messaging lets you send and receive
data when needed.
The EtherNet/IP communication modules support 128 Common Industrial
Protocol (CIP) connections over an EtherNet/IP network.
