Only job nets that meet the following conditions can be registered in a group.
The job net belongs to the same Project as the group.
The Execution condition is specified. The Execution condition is set to Time Startup. Only one execution time (one startup per day) is registered.
Copy and start is not specified in the job net properties.
Enabled Valid during job net execution is not set as the message event execution condition.
No identical job net exists in the group (identical job nets cannot be registered in the same group).
The job net is not registered in another group.
Information
When "start" is specified for a group, all job nets registered in the group start without waiting for an occurrence of the message event or for the startup time. Also, see "14.1.7 Group Operations and Actions".
If a job net residing in the preceding job net of the same group has been set to [Valid execution time], it waits for the normal termination of the preceding job net regardless of the [Wait for startup time] setup. Also, it waits for an occurrence of the message event and the Scheduled time. Also, see "4.3.1 Registering Groups".
