Quantum Communication Interface Modules
Overview
Nine types of communication interface modules are available and presented in the
table below, and are described in the following text.
Network Interface Modules
The following table shows the communication interface modules.
RIO Modules (CRP/CRA/NRP)
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
Type Description
RIO There are three types of RIO modules:
CRP: Single and dual channel Remote I/O interface modules (RIO heads)
connected via a coaxial cable network.
CRA: Single and dual channel Remote I/O interface modules (RIO drops)
connected via a coaxial cable network.
NRP: Remote I/O fiber optic repeater module (RIO head or drop) connected
via a coaxial cable network and fiber optic cables.
DIO Single and dual channel Distributed I/O interface modules connected via a
twisted pair Modbus Plus cable network.
NOM Single and dual channel Network Option Modules (NOM) connected via a
twisted pair Modbus Plus cable network.
Fiber Optic
Modbus Plus
Modbus Plus on fiber module connected via a fiber optic Modbus Plus cable
network.
Ethernet
