The Allen-Bradley 1788-CNCHKR is a pocket sized, field device used to check the quality of ControlNet network. This tool is ideally used as a commissioning and maintenance tool for evaluating the quality of installation of new and existing ControlNet networks.
The 1788-CNCHKR is capable of checking the quality signal by measuring the characteristics of signal such as Level of distortion, Noise or signal reflections, Rising and falling edges, Minimum message duration, Minimum between-message duration, Peak-to-peak amplitude and Violations to Manchester signal encoding. This tool also features a Node Finder and Oscilloscope output. Node finder is used for detecting a node in the ControlNet network, specified by the user through the built-in Thumbwheel switches. The oscilloscope output is used for providing trigger signal and isolated network signal for displaying messages of specific node in the oscilloscope.
