I-8831-80 embedded controller

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-8831 can be used in remote data acquisition and control applications, including environment monitoring, power management and factory automation.

Features

• Equipped with MiniOS7, ,an embedded OS similar to DOS that is developed by ICP DAS Co., LTD.
• Support IPv4.
• Provides full C library functions such as 8K, 87K I/O, 7-segment LED, RTC (real time clock), EEPROM etc.
• Firmware can be updated via the RS-232 port.
• The XServer architecture greatly simplify the programming of TCP/IP protocol.
• Supports the VxComm technique for all ports (RS-232 and Ethernet).
• Provides a hardware serial number or an ASICKey to protect designated systems.
• Compact I/O Expansion slot allows the quick installation of I/O modules.
• 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 support i-8K and i-87K series I/O modules, such as DI/DO, AI/AO, Counter/Frequency modules.
• 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.
