1.3 Hardware
The ROC809 and ROC827 are highly innovative and versatile units
with an integrated backplane to which the central processor unit (CPU),
power input module, communication modules, and I/O modules
connect. The ROC809 (see
Figure 1-1
) has nine module slots, of which
three can house communication modules. The ROC827 base unit
(shown on the left-hand side of
Figure 1-2
) has three I/O module slots.
The ROC800-Series expansion backplanes (EXPs) attach to the
ROC827 base unit (see
Figure 1-2
). Each EXP provides six additional
I/O module slots. The ROC827 can support up to four EXPs, for a total
of 27 I/O module slots (six slots per EXP plus the three I/O slots on the
ROC827 base unit).
The ROC800s use a Power Input module to convert external input
power to the voltage levels required by the electronics and to monitor
voltage levels to ensure proper operation. Three Power Input modules—
12 Volts dc (PM-12), 24 Volts dc (PM-24), and 30 Volts dc (PM-30)—
are available. For more information on the Power Input modules, refer
to
Chapter 3, Power Connections
.
The ROC800s support a variety of communication protocols: ROC Plus,
Modbus, Modbus TCP/IP, Modbus encapsulated in TCP/IP, and
Modbus with Electronic Flow Measurement (EFM) extensions.
Figure 1-1
shows the housing, typical I/O modules, and communication
modules installed in a ROC809. The patented ABS (Acrylonitrile
Butadiene Styrene) plastic housing has wire covers to protect the wiring
terminals. The housing includes DIN rail mounts for mounting the unit
on a panel or in a user-supplied enclosure. Patent 6,771,513 covers the
ROC800 enclosure (refer to
