SetAlarm
The SetAlarm instruction generates the user-defined error that corresponds to event code Code. Event
codes are defined in the event setting table on the Sysmac Studio. The time of occurrence, event name,
event group, event code Code, event level, additional information Info1, additional information Info2, and
detailed information are stored in the user event log area that corresponds to the level of the event
code. The value for the time of occurrence is automatically obtained. The event name, event group, and
detailed information that are set from the Sysmac Studio are recorded. The event level that corresponds
to the event code is recorded. The event levels are given below. The smaller the event code is, the
higher the event level is.
The following figure shows a programming example. A user-defined error with event code 101 is gener-
ated. The values of variables abc and def are stored as attached information.
You can specify either global variables or local variables for Info1 and Info2.
• Up to 32 user-defined errors can be generated in each of the eight event levels (for up to 256 user-
defined errors total).
