Curtis 1356/1356P CAN Expansion Module Manual,
DIAGNOSTICS AND TROUBLESHOOTING
When an error occurs in the 1356 /1356P, a fault message can be monitored
through the Curtis programmer. Meanwhile, an emergency message will be
produced on the CAN bus according to the CANopen standard. This message
will be sent once. When the fault clears, a No Fault emergency message will
be transmitted.
The fault log is accessed by SDO reads of the Standard Object at Index
0x1003. Reading the Fault Log Length sub-index 0x00 will return a value of 16
(the depth of the fault log). Reading from the sub-index 1 though 16 (0x01 – 0x10)
will return the faults plus time stamps in order from newest to oldest. The fault
log can be cleared by writing 0 to the Fault Log Length object (sub-index 0x00).
Additionally, the highest priority fault code will be flashed on the red
and yellow status LEDs. The red LED enumerates the digit place and the yel-
low LED enumerates the value. For example, a code 23 would be displayed as
one red flash, followed by two yellow flashes, followed by two red flashes and
finished with three yellow flashes. The 1356 /1356P's two LEDs will display
this repeating pattern:
red
✱
(first digit)
The fault codes are listed in the troubleshooting chart (Table 5).
During normal operation, the yellow LED flashes continuously.
On power-up, the integrity of the code stored in memory is automatically
tested. If the software is found to be corrupted, the red Status LED will flash
rapidly.
The flash code can also be flashed on a single remote LED connected to the
serial port. For example, a code 23 would be displayed as two flashes, followed
by a 500 ms delay, and finished with three flashes. The 1356 /1356P will repeat
this pattern at 1 second intervals.
