10.3.1
Handling Run-Time Errors with the ERROR task
Certain run-time errors will cause the ERROR task to be invoked if it exists. This provides a
convenient way to safely handle the error condition and take whatever action is necessary, such as
a controlled stop of the system or signalling of an alarm.
When an ERROR task runs, all other tasks will have been stopped. Therefore the ERROR task has
exclusive execution rights. Once the ERROR task has completed, the program ends and no other
tasks operate.
When the option module is reset (Pr
S.00.007
= On (1)), this will restart the user program (providing
auto-run Pr
S.01.013
=1) and clear any drive trip. This reset action can be performed at any time,
not just after a run-time error or in an ERROR task.
The task that caused a run-time error can be determined by reading Pr
S.01.050
.

Ethernet error codes
If the option module detects an Ethernet error during operation, it will force a SlotX Error trip on the
drive with a sub trip string. Table 10-3 shows the possible Ethernet error codes and sub trip string.
Table 10-3 Ethernet error codes
Drive trips do not cause the ERROR task to run. Only certain user program errors do.
