In this work, a method for detecting and correcting errors in Modbus-RTU communications is designed, implemented, and assessed in a smart metering application. This is a low-cost solution for improving communication quality in conventional Modbus-RTU architectures with copper fieldbus. It consists of introducing error detection and correction devices in the network segments most susceptible to errors caused by electromagnetic interference. Experimental validations were conducted and demonstrated the effectiveness of this method for isolating noisy segments in the communication bus, maintaining full compatibility with commercial devices and improving the performance of the entire network.

“…In [17], the authors have addressed the transmission quality improvement in industrial communications based on Modbus RTU, using relay devices with the ability to detect and correct errors. This method respects the Modbus RTU protocol parameters, so that the enhanced bus with relay devices can be used together with common devices.…”

“…Tests performed on repeaters/error correctors validate the fulfillment of design requirements and demonstrate their effectiveness in improving transmission quality for industrial Modbus RTU data transmission networks. The authors in [17] present the design and implementation of error detection and correction scheme in a Modbus RTU network based on the REED-SOLOMON code. Parity bits transmission is done following Modbus protocol parameters, so the bus can be used by common devices without error detection/correction scheme.…”

Few developments have changed the evolution of the automation process as substantially as the development of industrial local area networks and communication protocols. Especially fieldbus systems, networks created for the lowest levels of the automation hierarchy, have an enormous influence on the flexibility and performance of modern automation systems in all application areas. The technique of updating data on Modbus type devices involves a procedure of reading data at regular time intervals called pooling. Some automation processes include interdependence between different control variables belonging to different hardware devices. This paper presents and analyzes various scenarios related to a variable architecture configuration of physical modules based on Modbus communication protocol. The proposed Modbus Extension (ModbusE) concept is presented by defining the new optimized message format, and the structure of the acquisition cycle to obtain a deterministic temporal behavior, solutions for describing devices at the Modbus protocol level being presented. The status update of each Modbus module is done according to the address of the device, but also the number of registers per device. The paper analyses the worst-case scenario of communication involving Modbus devices on the same network and exchanging data corresponding to one or more server registers.INDEX TERMS Modbus, local industrial networks, acquisition cycle, fieldbus.
