Hi, First of all, Scale PLC analog input from 0 - 16000 to -80 to 120. (or -800 to 1200 if you want to represent one decimal). This value should be represented as an integer data type in the CS1. See CS1/CJ1 Scaling on this website for help with scaling. Secondly, set up a 'numeral display' object using NTST on the NT631 as shown below. Also configure the numeral table as shown with 'binary' data type. Note that the 'System' data type may also be preset to binary depending on your project. Note that my example will display values -800 to 1200 as -80.0 to 120.0. Nibroc
