Eric @ SM Posted August 2, 2012 Report Share Posted August 2, 2012 Tech in the field did an install of two ultrasonic 4-20mA sensors for product tank level indication of a V570-57-T20B + EX-A2X + DI16 + RO8 + ATC8. The bit value assigned to the two inputs of the ATC8 are changing, but the display appears to lag and/or not update. I've looked at the VLP file and cannot see why it would act in this manner. If the tech does an initialize & reset, the display is updated. The only thing that I can even think of, is the the MI used as a source for the display was also used as a source for a string, as there were going to be serial slave displays, which are not going to be used. I have half a notion to tell the tech to disable that net of the VLP and see how it acts (it has a timer block incorporated). With the exception of the net for storing data in the string, this program has been used by our company for the past couple years w/out issue but I don't see how it should affect the screen display update...?
