Develop Integrated Motion over an EtherNet/IP Network Application Chapter 10
Maximum Number of Position
Loop-configured Drives
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 EtherNet/IP Network
on page 73.
Drives are counted among the number of nodes in the I/O Configuration section
of the Logix Designer application. If you use the maximum number of drives that
a Compact GuardLogix 5370 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-L30ERMS controller supports a maximum of four
Position Loop-configured drives.
Table 30
lists motion-related specification information for the controllers that
support Integrated Motion over an EtherNet/IP network.
If your solution requires more than 16 Position Loop-configured drives,
consider using the ControlLogix® platform. The ControlLogix platform
enables up to 100 Position Loop-configured drives.
