Using Multi-Drive Mode
Chapter 8 provides information to explain how to use Multi-Drive
mode.
8.1 Single Mode vs. Multi-Drive Mode
The MDI interface provides a means to connect up to five drives on
one node daisy-chained over the RS-485. Two different operation
modes, single and multiple drive modes, are possible.
Single mode is a typical network installation, where a single
Profibus node consists of a single drive with a MDCOMM-PBUS
module. In this mode, the module can talk to one host, and the host
can support one additional external peripheral (OIM or MDCOMM-
232) over MDI.
