  Introduction
The I-8431/ I-8831 are ethernet embedded controller with 4/8 I/O slots. Both are equipped with MiniOS7,an embedded OS similar to DOS that is developed by ICPDAS Co., LTD.

The MiniOS7 can boot up in a very short time (0.4~0.8 second).It has built-in hardware diagnostic function, and supports the full functions to access all 8K and 87K series I/O modules, such as DI, DO, DIO, AI, AO, Counter/Frequency, motion modules etc.

To simplify the TCP/IP program developing process, we designed a XServer architecture. It is a reliable, opened, expandable, all purposed,and easily to be used library. The Xserver implements 90% functionalities of Ethernet communication. Refer the rich demo programs we provided, software engineer can easily finish the 10% remaining funtionalities and greatly shorten the developing time.

The I-8431/I-8831are equipped an ethernet port and their back planes are equipped three serial COM Port, they include RS-232 and RS-485 ports and can be used in remote data acquisition and control applications, including environment monitoring, power management and factory automation. By using S-256 (256 KBytes) or S-512 (512 KBytes)battery backup SRAM, they provide data logger storage function.

Note: S256 and S512 are optional accessories.

  Features  
 
  Provide multi Serial Port interface on back plane.
COM1: RS-232
COM3: RS-232/RS-485

COM4: RS-232   Provides a hardware serial number or an ASICKey to protect designated systems.

The built-in watchdog circuit will reset the CPU module if a failure occurs in either the hardware or software, allowing the controller system more reliable and stable in harsh and noisy environments.
Dual Bus designed to supports I-8K and I-87K series I/O modules, such as DI/DO, AI/AO, Counter/Frequency modules
Compact I/O Expansion slot allows the quick installation of various 8K and 87K I/O module
  The XServer architecture greatly simplify the programming of
  TCP/IP protocol.
  Supports the VxComm technique for all ports (Serial Port and
  Ethernet Port).
 
  Firmware updated via the RS-232 port

  Ventilated housing designed to operate between ¡V25¢XC to
  +75¢XC

  Using DIN rail clips or Screw poles around the corners
  allows the control unit to be easily mounted on the control
  box
  Frame Ground provides a path for bypassing ESD, allowing
  enhanced static protection (ESD) capability and ensures that
  the module is more reliable.


  Equipped with MiniOS7, an embedded OS similar to DOS that
  is developed by ICP DAS Co., LTD.

  Provides full C library functions such as 8K, 87K I/O, 7-
  segment LED, RTC (real time clock), EEPROM etc.
