Connection Overview A Logix5000 system uses a connection to establish a communication
link between two devices. Connections can be:
• controller to local I/O modules or local communication modules
• controller to remote I/O or remote communication modules
• controller to remote I/O (rack-optimized) modules
• produced and consumed tags
• messages
• controller access by RSLogix 5000 programming software
• controller access by RSLinx software for HMI or other
applications
The limit of connections may ultimately reside in the communication
module you use for the connection. If a message path routes through
a communication module, the connection related to the message also
counts towards the connection limit of that communication module.
Other controllers and communication modules support different
maximum numbers of connections.
For more information... The Logix5000 Controllers Design Considerations Reference Manual,
1756-RM094 describes how to optimize connection use.
