Figure 32 Connecting Powermonitor 3000 to Computer Communications Port
Optional Remote I/O Communications
Powermonitor 3000 units with a catalog number ending in -RIO are
equipped with a Remote I/O port in addition to the native RS-485
port. Allen-Bradley Remote I/O is a robust, widely used industrial data
network that uses twinaxial cable as its physical media. The
Powermonitor 3000 emulates a logical quarter rack and supports both
polled I/O and block transfer communications. The Remote I/O port
and the native RS-485 port may be used simultaneously, although
overall data throughput may be reduced.
Remote I/O communications wiring should be installed in a
daisy-chain configuration. We recommend the use of Belden 9463
twinaxial cable or equivalent. The maximum cable length is shown in
