Description of Atrium Processor LEDs
(Original Document)
Labeling of the LEDs
Six LEDs (RUN, TER, BAT, I/O, FIP and ERR) found on the processor card enable fast diagnostics of the status of the PLC station.
LEDs on the TSX PCI 57 card:
Due to the small amount of space available on the shield, only the ERR LED is visible when the PC housing the processor is closed.
For better user-friendliness, the state of the RUN, I/O, ERR and FIP LEDs is displayed via a utility in the task bar in Windows 2000 or Windows XP on the PC with the processor card. This functionality is only available when the host PC is running (PCIWAY driver installed)
Description
The following table describes the role of each LED:
Display LED
On
Flashing
Off
BAT
(red)
  • battery missing,
  • battery flat,
  • battery the wrong way round,
  • wrong type of battery.
-
Running normally.
RUN
(green)
PLC running normally, program executing.
PLC in STOP mode or blocked by software error.
  • PLC not configured: application missing, invalid or incompatible,
  • PLC error: processor or system error.
TER
(yellow)
-
Terminal port link active. The rate of flashing is relative to the amount of traffic.
Link not active.
I/O
(red)
Input/Output errors coming from a module, a channel or a configuration error.
X-Bus error.
Normal state, no internal error.
FIP
(yellow)
-
Fipio bus link active. The rate of flashing is relative to the amount of traffic.
Link not active.
ERR
(red)
Processor or system error.
  • PLC not configured (application missing, invalid or incompatible),
  • PLC blocked by a software error,
  • Memory card battery error,
  • X-Bus error.
Normal state, no internal error.
NOTE:
  • An X-Bus error is indicated by simultaneous flashing of the ERR and I/O LEDs.
  • The FIP LED is only present on the TSX PCI 57 354 processor.
