Where wiring cost is a concern, it may be more cost-effective to distribute I/O points closer to the field devices they control. Field I/O modules can pass I/O data to/from the controller with one single communications link. Terminator field I/O Network Interface Modules offer Ethernet, DeviceNet, Modbus RTU, or Profibus communication.
The Terminator I/O MODBUS network interface module allows you to
connect I/O as a slave station on a MODBUS RTU network. The
T1K-MODBUS can communicate with any MODBUS RTU network master using
high-level MODBUS commands.
MODBUS Communications - MODBUS RTU Master Some of our DirectLOGIC
Programmable Logic Controllers (PLCs) can be used as MODBUS masters,
directly through a communication port on the CPU. (Consult
our "PLC Hardware" product category Web site sections or our product
catalog for more information.)
Ethernet Networking - T1H-EBC100 module
The T1H-EBC100 module provides a low-cost, high-performance Ethernet
link between Terminator I/O and your MODBUS TCP Master, PC-based
control or WinPLC/ DL205/ DL405 CPUs using the H*-ERM module for
Inexpensive cables and connecting devices
The Terminator EBC modules are made with industry standard RJ45
connections for easy networking. Off-the-shelf Ethernet
hubs and repeaters make configuring a network a breeze.
No DIP-switch settings All addressing and
set-up features are configurable through the software configuration
tool. All I/O data is passed into the EBC buffer and communicated
as a block almost instantaneously to the host device.
Adding I/O modules The T1H-EBC100 modules
support the full line-up of Terminator I/O discrete and analog
Supported protocols The T1H-EBC100 module
supports TCP/ IP, UDP/ IP, IPX and the MODBUS TCP/IP application
layer protocol at 100 Mbps maximum.
Network masters Network masters include any
MODBUS TCP master (PLC, PC, or other), the DL205 and DL405 DirectLOGIC
PLCs and WinPLCs using the Ethernet Remote Master module (ERM), and
PCs using PC-based control software that includes MODBUS TCP
Ethernet I/O drivers.
T1H-EBC100 as H*-ERM slave When using a DirectLOGIC
CPU with an ERM module as the network master, the T1H-EBC100 slave
will provide fast analog I/O update times.
Save money on your Terminator I/O system when compared with
competitive I/O alternatives
Virtually unlimited number of I/O points (Up to sixteen
modules per EBC system)
Deterministic I/O updates on dedicated networks
Use off-the-shelf networking components to connect to your
Fast I/O updates of less than 1 ms per base
On-board serial port for operator panel, or ASCII devices
Profibus Slave (T1H-PBC module)
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 hardwiring costs. Profibus provides
specifications for information exchanged between nodes, such as
controller data associated with low-level device and configuration
parameters individually related to system operations.
DeviceNET Slave (T1K-DEVNETS module)
If you are already using or planning to implement a DeviceNET
controller network, our Terminator I/O subsystem will help further
reduce the cost of your overall application. We now offer the
T1K-DEVNETS (slave) module, which allows our Terminator I/O subsystem
to be linked with a DeviceNET master controller.
DeviceNET is a lowcost control network that provides a common method
to connect on a single network. This advanced communications media
and software is referred to as DeviceNET and significantly reduces
hardwiring costs. DeviceNET provides specifications for information
exchanged between nodes, such as controller data associated with
low-level devices and configuration parameters individually related
to system operations.
