Design of MOD-CAN Interface Card Based on OPC Technology

The actuality that SHCAN2000 system relies on FIX configuration software has limited its application scope significantly. In this paper, the interface card what accord with OPC specification was realized through applying LM3S8962 microcontroller and OPC technology, the opening performance of data acquisition system was greatly improved, which can effectively avoid the repeatability of development process and incompatibility of many integrated software systems, at the same time, the standardization of hardware and software was also fulfilled the requirements. The improved Field Bus control system has a broader application prospect in industrial control field.
