•
Red LED HLT (HaLTed) means a serious fault. The controller has stopped. The system
halt information is probably missing or incomplete. The recommended actions are:
1.
Restart the controller. See
Section 5.5.15, System Restart following Maintenance
.
If HLT still occurs it is possible to interpret new halt code information from the display
and continue with step 2.
2.
Reload the software and restart. See example in
Section 5.5.17, Loading of Application
If HLT still occurs continue with step 3.
3.
Replace the processor module.
•
Yellow LED TO (Time Out). Normally OFF. Sometimes it flashes under normal
conditions to indicate that an I/O board has been addressed but does not respond. A board
can be withdrawn for repair or a board can fail.
•
Green LED BC means that the backup voltage for RAM is connected
•
Green LED DUAL means that a redundant processor is ready. If the controller includes
two processor modules both of them should normally indicate DUAL.
•
The character display normally show the working mode of the controller (P1, P2 and so
on). See Chapter 4. If anything else is presented, the system has probably stopped and the
stop code can be read from
. This section also includes
corrective actions.
•
The four LEDs close to the service port show the status of the communication with a
connected engineering station
–
Yellow LED HI I - High speed input
–
Yellow LED HI O - High speed output
–
Yellow LED LO I - Low speed input
–
Yellow LED LO O - Low speed output.
5.5.9.8 I/O
This section deals with the S100 I/O. Follow the instructions and make conclusions applicable.
The corresponding information for the S400 I/O and S800 I/O can be found in a separate user’s
guide MasterFieldbus and S400 I/O and S800 I/O User’s Guide respectively.
•
Each I/O board has a red Fault indication LED. Replace a board with a LED which
indicate a fault. First read
Section 5.5.10.1, Board and Subrack Mounted Unit Exchange
•
Check whether the circuit board is activated in the data base.
•
If all I/O boards indicate fault check that the system is not in CONFIGURATION mode.
