[ISS Support Case] How to reference a BIT in a MODBUS register

Last updated: March 6th, 2025

Description

Direct Email: Any recommendation on how to decode an integer into individual bits? I have some devices that give alarms as a 16 bit integer but each bit represents a different alarm or warning. Usually from a TI PLC you can read V100.1 etc. but evidently you cant read these MODBUS register bits individually. I believe I can do this in an InTouch app but really only want to display the alarms on PI that is feed from the Wonderware Historian.
