The ScreenLogic interface shows acid and chlorine dosing on a timeline. The bars that indicate the dosing times have different widths--the width of the bar probably indicates the amount of the dose.
The amount of acid/chlorine used/remaining is also indicated in a six segment bar graph.
I don't think the ScreenLogic interface has a way to get the actual dose amounts, but maybe the data it uses for this history chart is available somewhere? I was thinking I could get the actual dosage amount from that data.
Has anybody found something like that, either in a local file on a laptop, or by "eavesdropping" on the RS-485 bus?
