Text Status Indication
A text indicator for the slice relates whether the slice is OK (Green) or BAD (Red). If the
slice is BAD then the system cannot determine the pre-defined slice at the specified slot
address. This indicates either the slice is missing, or there is a problem with the main BUS
power. If the surrounding slices also indicate BAD, it is most likely the main power is a
problem. If a single slice is BAD, then it most likely a missing slice, a failed slice, or the
wrong type of slice is installed in the slot.
LED Status Indication
A graphic indicator located at the top of each slice
provides power and availability status for each
slice in the PLC rack.
•
Single Green LED
– The slice is OK. The
correct slice is installed in the slot and not
reporting any issues with either the primary
or IO power busses.
•
Single Red LED
– The slice is BAD. There
is most likely a missing slice, a failed slice,
or the wrong type of slice is installed in the
slot.
•
Green and Red LED
– The slice is OK, the primary power bus to the slice is indicat-
ing a problem. The slice is installed correctly however the power source for the primary
power bus is indicating a problem.
•
Green and Yellow LED
– The slice is OK, the IO power bus to the slice is indicating a
problem. The slice is installed correctly however power source for the IO power bus is
indicating a problem.
•
Green, Red, and Yellow LED
– The slice is OK, the IO and Bus power to the slice
indicate a problem. The slice is installed correctly however the power sources for both
the IO and primary busses are indicating a problem.
•
No LED indicators
– The slice is RESERVED. The correct slice is installed in the slot
however this slice is not required for the given system configuration.
•
‘X’ Indicator
– The slice is not applicable. The correct slice is installed in the slot
however the system configuration does not require the slice. The slice has been
installed to properly maintain the slot addressing.
