Chapter 11 Develop Integrated Motion over an EtherNet/IP Network Application
Maximum Number of
Position Loop-configured
Drives
The CompactLogix 5370 controllers support a maximum number of
EtherNet/IP nodes in a project. Any device added to the local Ethernet node in
the I/O configuration is counted toward the node limitation of the controller.
For more information, see Nodes on an EtherNet/IP Network on page 123
.
Drives are counted among the number of nodes in the I/O Configuration
section of the Studio 5000® environment. If you use the maximum number of
drives that a 1769-L18ERM-BB1B, 1769-L27ERM-QBFC1B,

controller supports in one system, you cannot add other
EtherNet/IP devices to that project.
Position Loop-configured Drive Limits
Among the maximum number drives supported by the controllers, there is a
maximum number of Position Loop-configured drives that are supported in
the project for the controller.
For example, the 1769-L30ERM controller supports a maximum of four
Position Loop-configured drives.
