Network Accessories
Repeaters
For extending CTNet cable segments and
creating star topologies, there are three
types of repeaters available (see At-a-Glance
table on previous page).
CTNet Cable
Control Techniques stocks a high-quality
shielded twisted-pair cable suitable for
high-speed data transmission.
PC Network Interface Card
For desktop and laptop computers,
use the USB22-CTNet network card.
This interface card provides direct
access to all of the drive and I/O
modes in a system.
CTNet I/O
A high-quality modular I/O system is available for CTNet
systems. Remote systems for CTNet include a bus coupler
and a large variety of snap-on terminal
blocks allowing up to 256 digital
inputs or outputs and up to 100
analog inputs and outputs per bus
coupler. Up to 64 remote I/O systems
can be attached to a CTNet network.
I/O points can be easily read or written.
The range of CTNet I/O options include:
• Digital input terminals in 5, 24, and 48Vdc, 120Vac
• Digital output terminals 5 and 24Vdc, Relay Output
(115-400Vac)
• Analog input and output terminals for a wide array
of applications. All standard voltages, mA, RTD,
thermocouple, etc.
Application Coprocessor Platforms
SM-Applications Plus / SM-Register Option Modules
SM-Applications Plus and SM-Register snap-in coprocessors
include CTNet high-speed peer-to-peer eldbus connectivity.
These CTNet-equipped coprocessors are based on a high-
performance microprocessor with up to 384KB of program
storage and 80KB of variable storage for user applications.
In addition to the CTNet eldbus, serial ports are available
for RS485 communications. The coprocessors also include
a built-in counter-timer unit and position controller
capability.
The Digitax ST-P Servo drive includes a built-in coprocessor
with the same functionality as the SM-Application Plus
Option Module.
