played even if the status of the monitored PC bit changes back from ON to OFF
(7-3-3 “Bit Memory Tables”, page 295). After checking the error at the equip-
ment, one of the following methods must be used to return to the screen that was
displayed before the error occurred: using a touch switch with the switch screen
function (page 334), writing a screen number to the control area (page 265), or
switching the screen by using a bit memory table (page 295).
Example: Displaying a screen that shows details of the error when the “TEMPERATURE AB-
