Method and arrangement for monitoring a transmission medium

摘要

Field devices are commonly used in unprotected environments, which means that these field devices and the conductor pairs connecting the field devices to the input modules/output modules of an automation installation are exposed to significant climatic and environmental factors. These factors have a detrimental effect on the transmission quality of the signals to be transferred between field devices and modules, which may result in erroneous measurements and dangerous operating states during control of a technical process. Measures to simplify monitoring of the transmission medium are proposed.
