Improving Inter-processor Data Transfer Rates over Industrial Networks

Abstract

Industrial networks allow information exchange between processors connected to them in industrial automation systems. Special protocols are used for inter- processor communication over industrial networks. In order to achieve optimum functionality, the inter- processor communication should be in real time. Data reduction and compression algorithms are used to transfer the information in a relatively short period of time. Data reduction algorithms can be used to improve information transfer rates over the industrial networks to achieve better performance. However, the nature of industrial networks demands special data reduction techniques compared to other networks. This paper proposes a data reduction algorithm for industrial networks. The proposed data reduction algorithm is based on a commonly used industrial protocol called Controller Area Network (CAN) protocol. However, the presented algorithm may be extended to other communication protocols without the loss of generality.
