RIO Modules
(CRA/CRP)
Quantum RIO head and drop modules use a S908-based networking I/O
configuration. Communication is done via single or dual coaxial cabling up to 15,000
feet away. This configuration supports a mix of the following product lines:
z SY/MAX
z 200 Series
z 500 Series
z 800 Series
z Quantum I/O
When Quantum RIO is required, the Quantum controller may support up to 31 RIO
drops. In an RIO configuration, an RIO head module is connected with coaxial cable
to RIO drop modules at each remote drop.
DIO Module
(CRA)
Quantum DIO is implemented over a Modbus Plus network. The CPU or NOMs
module may be the network head via their Modbus Plus ports.
Quantum DIO Modbus Plus drop adaptors are specifically designed to link Quantum
I/O modules to the head via twisted pair shielded cable (Modbus Plus). The DIO
drop modules also provide the I/O with power (maximum 3A) from a 24 Vdc or a 115/
230 Vac source. Each DIO network supports up to 63 distributed drops using
repeaters.
Network Option
Module (NOM)
Quantum NOM modules provide extended communication capabilities for the
Quantum system within a Modbus Plus configuration.
Modbus Plus on
Fiber Module
(NOM)
Quantum Modbus Plus on Fiber modules provides connectivity to Modbus Plus
nodes by fiber cable without fiber optic repeaters, and allows the creation of a pure
fiber optic network or a mixed fiber optic/twisted-pair network (with the use of a
490NRP254 Fiber Optic Repeater).
Ethernet TCP/IP
(NOE) Modules
Quantum Ethernet TCP/IP modules make it possible for a Quantum controller to
communicate with devices on an Ethernet network using TCP/IP – the de facto
standard protocol. An Ethernet module may be inserted into an existing Quantum
system and connected to existing Ethernet networks via fiber optic or twisted pair
cabling.
SY/MAX Ethernet
Modules (NOE)
Quantum-SY/MAX-Ethernet modules are Quantum CPU network option modules
that can be placed in a Quantum backplane to connect Quantum controllers to SY/
MAX devices and applications.
MMS-Ethernet
Modules (NOE)
Quantum-MMS-Ethernet modules are Quantum CPU network option modules that
can be placed in a Quantum backplane to connect Quantum controllers to MMS
devices and applications.
