Develop Integrated Motion over an EtherNet/IP Network Application
Chapter 11
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 125
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, 1769-L30ERM,
1769-L33ERM, or 1769-L36ERM 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.
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.
