VDI 4201 Blatt 3:2012-07 (R2018)

This guideline specifies the specific requirements for the realization of a digital interface on the basis of Modbus. It details the general performance criteria on digital interfaces for data exchange between automated measuring and electronic data evaluation systems for monitoring emissions specified in guideline VDI 4201 Part 1. The requirements of this guideline are used together with the requirements of VDI 4201 Part 1 in performance tests of automated measuring and electronic data evaluation systems equipped with digital interfaces on the basis of Modbus. This guideline meets together with guideline VDI 4201 Part 1 the requirements of the Uniform Practice in Monitoring Emissions (Bundeseinheitliche Praxis bei der Überwachung der Emissionen) and of DIN EN 15267-3 with respect to a complete description of the digital interface in the relevant standards and guidelines. This guideline may be applied only in conjunction with guideline VDI 4201 Part 1. It is addressed to manufactures of automated measuring and electronic data evaluation systems for monitoring emissions, to test institutes performing performance tests of such systems, and to the authorities responsible for the declaration of suitability. Furthermore, it assists users of performance-tested systems for monitoring emissions in the operation of these systems.
