Introduction
The i-8000 is
a family of compact, modular, intelligent and rugged, distributed
embedded I/O controller designed for data
acquisition and control in manufacturing, research and education.
This new exciting series offers a flexible, versatile, and
economical solution to a wide range of applications. From
Data-Acquisition, process control, test and measurement, to energy
and building management.
The i-8000 is a modular network -based
embedded I/O controller with the capability of connecting I/O either through it¡¦s own
dual backplane bus or alternatively through remote I/O units and
remote I/O modules. The unit comprises a main control unit with a
range of standard communication interfaces, and a dual backplane bus
permitting I/O expansion.
The dual backplane
bus is hybrid in nature providing the facility to connect either
serial (i-87K I/O) or parallel I/O modules (i-8000 I/O). The
parallel bus is used for high speed data transfer application. There
are various of I/O modules including Digital Input/ Output , Analog
Input/ Output, Counter/ Frequency and Motion I/O modules.
TThe i-8000 can
be used as an intelligent distributed data acquisition front end
connected to a Host machine running a standard SCADA package, or
alternatively. It can be user programmed as an autonomous controller
running an embedded software application. Significant non-volatile
memory is available for data and program storage. |

Support for Virtual COM
technology |
¡@ |
| |
Using the VxComm technology, PC can create
virtual COM ports to map the RS-232, RS-485 of the i-8441/8841.
The software running on the PC can operate the virtual COM ports
like a standard COM port to access the serial devices connect to the
i-8441/8841. That is to say, the original software developed for
the serial devices can access the serial devices via the
Ethernet/Internet without any modification.
Each PC can control up to 256 COM ports
(including real COM ports). Using the multi serial port I/O module
(i-8142,i-8144,i-8112,i-8114) , each i-8441/8841 can have extra
16 COM ports. |

Support Modbus
Protocol |
¡@ |
| |
Using the Modbus firmware, i-8441/8841 offers
following Modbus features:
- Modbus/TCP/RTU/ASCII slave
- Modbus/TCP/RTU/ASCII master
- Gateway for Modbus/TCP to Modbus/RTU

Easy-to-use software development
tool kits (using C language) |
¡@ |
| |
If the default firmware does not totally fulfill
the user's application needs, custom firmware can be developed for
i-8441/8841 using the SDK (Xserver, Modbus library) provided by
ICPDAS. |

i-8441/8841 has a build-in web server for
configuration. You can use standard web browsers (such as IE,
Netscape, Firefox,..etc) to configure its Ethernet and COM ports
configurations. |

Remote Configuration/Maintenance |
¡@ |
| |
i-8441/8841 can be operated via the Ethernet
(TCP/IP or UDP) or RS-232, to allow tasks such as downloading
programs, configuration, updating the MiniOS7, etc. |

Built-in watchdog timer (WDT) |
¡@ |
| |
i-8441/8841 include an internal watchdog timer
(WDT). The watchdog timer will trigger a system reset if the main
program fails or neglects to regularly service the watchdog. The
intention is to bring the system back from the hung state into
normal operation. |

Dual I/O Bus Interface
(Parallel bus for i-8000
I/O modules, Serial Bus for i-87K I/O modules) |
¡@ |
| |
The i-8441/8841 support both i-8000 and i-87K
I/O modules. ICPDAS provides all function libraries and demo
programs which can help developing customer's application. |
