I-8431-G CR ICP DAS MiniOS7 Based

• 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 –25°C to  +75°C
• 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.

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.
