Panic data
Cause
The watchdog timer alarm occurred on CPU
Unit.
Provide remedy following instructions in the
manual of the CPU Unit.
Time out of the cyclic monitor time.
The followings are the possible causes:
• End refresh is prohibited on CPU Unit.
• The scan time of CPU Unit is too long.
Remedies:
Enable end refresh
Set the longer cyclic monitor time.
CPU Unit Bus error
Fatal error occurred on CPU Unit.
Check if MC Unit is mounted on the backplane
correctly. If the error persists even after the
checking and correction, CPU Unit or the back-
plane may be broken. Replace it as needed.
Non-fatal error occurred on CPU Unit.
Provide remedy following instructions in the
manual of CPU Unit.
Transfer not possible because there is no Unit
for the specified unit number
Normally, this error does not occur. If it should
occur, report to OMRON.
Transfer not possible because the destination
address in the routing table has not been set.
Normally, this error does not occur. If it should
occur, report to OMRON.
Transfer not possible because of a routing table
error.
Normally, this error does not occur. If it should
occur, report to OMRON.
An incorrect packet has been transferred.
Normally, this error does not occur. If it should
occur, report to OMRON.
Routing not possible because the maximum
frame length has been exceeded.
Normally, this error does not occur. If it should
occur, report to OMRON.
Set if trap processing has been executed.
Normally, this error does not occur. If it should
occur, report to OMRON.
