I am using a PanelView 1000 and AB SLC5/04 PLC.
The screen I have set up consists of a maintained push-button for setting control mode (AUTO/MANUAL), a numeric entry block for setting the manual setpoint, and two monentary buttons to increment/decrement the setpoint in manual mode.
The issue I have is that when the screen is changed or goes to the screensaver, the "MODE" button goes to the 0, AUTO, position re-setting the setpoint to 0. The setpoint change is correct for the AUTO mode at this time.
AB support recommended changing the tag registers for the push button. This worked on some system but not on others. I have changed the tags to different points within the same registry and that corrected the problem as well. AB has no explanaition for any of this.
Has anybody had similar expierences or know the cause of the issue?
