6-24 Communicating with Devices on an EtherNet/IP Link
One chassis can have a combination of some modules configured as a direct
connection and others as rack optimized.
Example 1: Total connections required by DriveLogix1
The following table calculates the connections used in this example.
If you configured the remote I/O modules as rack-optimized, you would only
need a rack-optimized connection to the 1794-AENT, reducing the above
example by 3 connections.
Connection: Amount:
DriveLogix1 controller to 3 local I/O modules
rack-optimized connection for the DIN rail
direct connection for each I/O module
1
3
DriveLogix1 controller to remote 1794-AENT 1
DriveLogix1 to 4 remote I/O modules (through
1794-AENT)
all I/O modules configured as direct connection
no connection to the 1794-AENT
4
total connections used: 9
