 Self-Tuner
design
The I-7520 contains a "Self Tuner" ASIC on the modules.
This chip can auto tune the data baud rate and data format in
the whole RS-485 network. In otherwords, the user may use it via
RS-485 network to link PLC, RS-485 device, RS-232 device and other
PC. Even the data format and data baud rate of those devices is
different.
 Intelligent
design
I-7000 modules provides signal conditioning system monitoring,
alarm signal output, safe value setting
I/O Range Programmable
I/O type and range of modules can be configurable. The users select
the type and range remotely by issuing command from the host.
You can use fewer modules for different applications. It can increase
application flexibility and lower the maintenance cost.
Dual Watchdog Design
I-7000 Provides Module and Host Watchdog. The module watchdog
is a hardware watchdog. The host watchdog is a software watchdog.
The module watchdog is designed to automatically reset the microprocessor
when the module fails. The host watchdog monitors the host controller
(PC or PLC). The output of module can go to the safe Value State
if the host fails.
Stand Alone Control
The user may use the I-7188 embedded control module to control
the I/O ports of I-7000 module directly without host. The user
can download an application program to the flash memory of I-7188
from the host via the RS-232 port.
Wide Range Power Input
The I-7000 requires 10V to 30V unregulated DC power supply.
Easy mounting and connection
The user may mount the modules on a DIN rail, Panel or Wall. The
user can use the screw-terminal block to connect the signals
Host Swap Design
The Plug-in terminal blocks are used in I-7000 modules. The user
may hot-swap the modules directly and lower the maintenance effort.
RS-485 Industrial Multi-Drop network
The I-7000 series modules use the industrial EIA RS-485 communication
protocol to transmit and recive data at high speed over long distances.
All modules have been designed to be easy to interface to the
populuar computer and controller. All communcation to and from
the modules is performed with printable ASCII charcaters. All
modules use high speed photocouple to prevent common mode problem.
Internal surge protection circuitry is used on data lines to protect
the modules from spikes.
RS-232 to RS-485 conversion
The user can use the I-7520 RS-232/RS-485 converter, ISA-7520R
or PCI-7520AR to change standard RS-232 signals into isolated
RS-485 signals. ISA-7520R is an ISA bus RS-485 board and the function
is the same as I-7520R. PCI-7520AR is a PCIbus RS-485/RS-422 board
and the function is similar to I-7520AR. RS-485 bus control is
transparent to the user and the user doesn't have to understand
the real operation. Host software is simple written in half-duplex
RS-232 like.
Why "Self Tuner"
In indutrial application system, the user may use RS-485 network
to link PLC, PC, RS-232 device, machine ...etc. Because the data
baud rate and the data format of those device is different, it
is impossible for the converter to link them. The I-7520 contains
a patented "Self Tuner" ASIC. This chip can auto-tune
the baud and data format in whole RS-485 network. It also handle
the direction of the RS-485 communication line. Since the unique
features of this ASIC, you can implement a very flexible RS-485
network system. The user don't have to open the plastic case of
I-7520 to select a correct dip switch for different baud rate
and data format.
Communication protocol
All I-7000 modules use a simple command /response protocol for
communication. A module must be interrogated by the host to obtain
data. A module can never initiate a command sequence. The user
can use high-level language, such as C, VB, Dephi ... to write
their application programs. Some famous packages can control I-7000
Directly. Such as Labview, HP VIEW, Testpoint, IsaGraf.... etc.
Network can be expandable
I-7510 repeater is more than a pure isolated repeater. "Self
Tuner" ASIC is inside. It has some outstanding features,
such as 3000V isolation, 115K maxi. speed, variable baud and data
format, Each I-7510 repeater can let you add 256 modules I-7000
modules to the network or extend the network to another 4,000ft
long. Logically you can access 2,056 modules in one RS-232 port.
Physically the user should consider the network length and the
hardware loading effect. The user should use I-7510 to isolate
different groups to avoid high volatge hitting the communication
wires.
