If a fault occurs, the LCD displays
Er
.
In interconnected plants, the address (device and segment number) of the control-
ler causing the fault is displayed on all the other controllers. But no address ap-
pears on the controller that caused the fault.
Example of display in interconnected plants:
50
20
06
02
= operating line
= error number
= segment number (LPB)
= device number (LPB)
The error message disappears only after the fault has been rectified. There is no
acknowledgement!
