Using Multi-Drive Mode
Chapter 7 provides information and a ControlLogix ladder example to
explain how to use Multi-Drive mode.
Single mode is a typical network installation, where a single EtherNet/IP
node consists of a single drive with a 22-COMM-E adapter (
Figure 7.1 ).
Figure 7.1 Single Mode Example for Network
Multi-Drive mode is an alternative to the typical network installation,
where a single EtherNet/IP node can consist of one to five drives
(
Figure 7.2 ). The first drive must be a PowerFlex 40 with a 22-COMM-E
adapter. The remaining drives can be PowerFlex 4 or PowerFlex 40
drives that are daisy-chained over RS-485 with the first drive.
