MODBUS协议由于其简单性和开放性，目前在现场和SCADA级别都非常流行。然而，物理传输介质的选择目前仅限于低性能TIA/EIA-485总线（MODBUS RTU）或以太网（MODBUS TCP），其拓扑和布线缺点以及额外的软件复杂性。在本文中，一个MODBUS适配层的控制器局域网（称为MODBUS CAN）的建议，正式验证，并进行实验评估。结果表明，在一个典型的低成本的嵌入式系统，其性能相比毫不逊色的MODBUS TCP实现，基于100 Mbps的以太网，在同一系统上进行，并使用相同的协议栈。
The MODBUS protocol is nowadays very popular at both the field and SCADA levels, thanks to its simplicity and its open nature. However, the choice of physical transmission medium is currently limited to either the low-performance TIA/EIA-485 bus (MODBUS RTU) or Ethernet (MODBUS TCP), with its topology and cabling shortcomings and additional software complexity. In this paper, a MODBUS adaptation layer for the Controller Area Network (called MODBUS CAN) is proposed, formally verified, and evaluated experimentally. The results show that, on a typical low-cost embedded system, its performance compares favorably with respect to a MODBUS TCP implementation, based on a 100Mbps Ethernet, carried out on the same system and using the same protocol stack.
