Bộ điều khiển lập trình nhúng PAC CPU 80188 + OS MiniOS7 +3 cổng RS-232/485 +1 cổng Ethernet + 8 cổng I/O Expansion ICP DAS I-8831-80
Introduction
The I-8431-80/I-8831-80 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-8431-80/I-8831-80 are 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.
Features
Provide multi Serial Port interface on back plane.
COM1: RS-232
COM3: RS-232/RS-485
COM4: RS-232
