| Abstract: | This paper presents a method to design a kind of equipment monitor and control system based on CAN bus. The system is consist of PLCs in different brands, one Master module and 30 Slaves, each of which has a STM32F107 MCU with Cortex-M3 core, containing an internal CAN bus controller that makes the CAN bus works efficiently. In addition,each module has multiple transmission interfaces and supports communication protocols of all the PLCs on line. |
