Hi all, I was wondering if anyone could shed some light on how I would go about controlling a data log with a primitive. I am using a G306 HMI and a CSMSTRV2 modular controller. I have created a data log and data tags for 8 TC's and I want to be able to turn the data logger on/off via buttons on the touch screen. Not sure if this even possible... Any help would be greatly appreciated.
