IEC 61158 Industrial Communication Networks, Fieldbus Specifications

    IEC 61158 Introduction

    IEC 61158 is a detailed standard of a fieldbus communication system as applied in industrial automation. It addresses several types of protocols and profiles to provide deterministic and real-time communication amongst sensors, actuators, controllers, and supervisory systems. The standard parameters include data link coatings, application layers, timing mechanisms, and interoperability regulations in support of distributed control network designs. Compliance has guaranteed integration, reliability, and uniform performance in multifaceted industrial communication networks.

    Get Certified IEC 61158 for Reliable Industrial Fieldbus Communication

    The IEC 61158 certification ascertains that fieldbus communication devices and networks satisfy internationally agreed prerequisites of real-time data exchange, interoperability, and deterministic operation. Certified systems can be used to improve efficiency, minimize delays in communications, and help in the effective distributed control of an industrial system.

    Scope of IEC 61158

    • Industrial automation on digital fieldbus communication networks. 
    • Gives communication protocols, layers, and message structures. 
    • Facilitates deterministic and real-time distributed control. 
    • Develops interoperability and multi-vendor compatibility requirements. 
    • Defines performance, time, and integrity of data. 
    • Could be applied to sensors, actuators, controllers, and supervisory control systems.

    IEC 61158 Equipment and Sample Preparation

    Specimen PreparationFieldbus communication devices, controllers, and network nodes are configured according to the intended industrial communication architecture.
    Specimen SizeComplete fieldbus networks or representative communication nodes are selected for functional and interoperability testing.

    IEC 61158 Technique, Process, and Data Collection

    The systems of fieldbus communication are set up and tested in controlled industrial network systems. Data packets are sent between machines to assess protocol compliance, time determinism, and fault management. Latency, packet loss, and throughput are captured by the network analysis and diagnostic tools. The obtained results are documented and compared with the IEC 61158 protocol and performance requirements to confirm the reliability and interoperability of communication.

    IEC 61158 Testing Procedure and Requirements

    Protocol Conformance TestVerify compliance with defined fieldbus communication protocols
    Data Transmission Integrity TestEnsure accurate and error-free data exchange between devices
    Compliance AuditConfirm adherence to IEC 61158 communication architecture and protocol specifications

    IEC 61158 Analysis Results and Interpretation

    The use of acceptable results makes it known that fieldbus networks are capable of deterministic real time communication, data integrity, and interoperability across multi-vendor devices. Constant latency and minimum errors in packets are good indicators of good communication performance. Deviations in protocol configuration, network optimization, or EMC suppression may be needed in case of nonconforming results. Adherence provides effective and reliable distributed industrial automation.
