system overview
If you are using a PROFIBUS™ controller
network, the Terminator I/O sub-system
will help further reduce the cost of your
overall application. The T1H-PBC module
allows the micro-modular Terminator I/O
sub-system to be linked with a PROFIBUS
master controller. PROFIBUS is a control
bus that provides a common method
to connect automation equipment with
devices on a single network. This standard
communications media is referred to as
PROFIBUS and significantly reduces hard-
wiring costs. PROFIBUS
provides specifica-
tions for information exchanged between
nodes, such as controller data associated
with low- level device and configuration
parameters individually related to system
operations.
PROFIBUS allows 32 stations per segment.
Segments vary in length depending on
the desired transmission speed. The
maximum speed is achieved on a segment
100 meters (327 feet) in length. Our
PROFIBUS-DP Slave represents a single
station. Repeaters also count as stations
and are used to extend the network to
greater distances. Our PROFIBUS module
supports baud rates of 9.6 Kbaud to 12
Mbaud depending on the network length.
Here’s how it works:
The T1H-PBC module is a PROFIBUS
slave, which can be plugged into
the network interface position of the
Terminator I/O micro-modular family of
I/O bases. This module reports all the
identification data, diagnostic information,
and parameters that control the module
operation. The T1H-PBC module scans
and reports all discrete and analog I/O
data to a PROFIBUS master. The exter-
nally-powered AC Terminator I/O base
units contain a 24VDC power supply for
simple wiring of sensors and actuators
into the Terminator I/O modules, and for
controlling them with a PROFIBUS master.
Using our PROFIBUS I/O sub-system
will increase installation flexibility as well
as save on wiring costs. The T1H-PBC
module supports all Terminator discrete
and analog I/O modules.
The T1H-PBC also offers the following
features:
•
Cost-effective:
With a single network for
devices, hardwiring costs are reduced.
•
Easy connectivity:
Low-cost installation is
easy to implement and maintain.
•
Diagnostics:
The PROFIBUS slave offers
advanced error diagnostics not commonly
available in traditional systems.
•
High baud rates:
Response time is 10 ms
per device
•
LED Indicators:
These provide quick indi-
cation of Terminator power and operating
mode.
