Rockwell Automation MD65 Profibus Communication Card - Manual (Page 62)

8-2 PROFIBUS Communications Module
Figure 8.2 shows that the Single Drive mode provides the possibility
of connecting one additional external peripheral.
Multi-Drive mode is an alternative to the typical network installation,
where a single Profibus node can consist of one to five drives (see
figure 8.3). The first drive must be a MD65 with a MDCOMM-PBUS
module. The remaining drives can be MD65 or MD60 drives that are
daisy-chained over RS-485 with the first drive.
