Linked job nets refer to master linked job nets, and so care is required when changing the job net information.
Changing the job flow for linked job nets
The job flow for linked job nets, and job nets at levels below the linked job nets, cannot be changed directly.
If the job flow for a master linked job net, or any job nets below the master linked job net is changed, the changes will be reflected to all of the linked job nets that refer to the changed job net, except for linked job nets that have been duplicated via a "copy and start" operation. The status of all of the jobs in the linked job nets where the changes are reflected will be "Waiting".
Note
If linked job nets or job nets (except for job nets that have been duplicated via a "copy and start" operation) at higher levels above the linked job nets are executing, the job flow for the master linked job net that the linked job nets refer to cannot be changed. Make the changes after the job net has terminated.
Changing job net information for linked job nets
Job net information for linked job nets, and job nets at levels below the linked job nets, cannot be changed. To change the job net information for a linked job net, change the master linked job net that the linked job net refers to.
The execution conditions for master linked job nets, and job nets at levels below the master linked job nets, cannot be changed. For other items, job net information can be changed in the same way as for normal child job nets. Except for the following items, the changes will be reflected to all of the linked job nets that refer to the changed job net. However, the changes will not be reflected to job nets that have been duplicated via a "copy and start" operation.
Items that are not reflected to linked job nets as a result of changes to the master linked job net
Instruction
The value will continue to be the value that was specified for the master linked job net when the linked job net was registered.
Base job net
This item is never specified regardless of the settings for the master linked job net.
Note
If linked job nets or job nets (except for job nets that have been duplicated via a "copy and start" operation) at higher levels above the linked job nets are executing, the job net information for the master linked job net that the linked job nets refer to cannot be changed. Make the changes after the job net has terminated.
Recovery-change for linked job nets
Recovery-change can be performed for linked job nets, and job nets at levels below the linked job nets.
However, it is not possible to perform recovery-change for master linked job nets, and job nets at levels below the master linked job nets.
Temporarily changing job information for linked job nets
Job information for linked job nets, and job nets at levels below the linked job nets, can be temporarily changed.
Job information for master linked job nets, and job nets at levels below the master linked job nets, cannot be temporarily changed.
Exception days for linked job nets
The startup days for linked job nets, and job nets at levels below the linked job nets, cannot be changed directly.
For master linked job nets, and job nets at levels below the master linked job nets, exception days can be specified in the Startup Days window. Exception days will be reflected to all of the linked job nets that refer to the changed job net, except for those job nets that have been duplicated via a "copy and start" operation. Exception days are reflected even if a linked job net that refers to the job net to be changed is running.
Changing remarks for linked job nets
Remarks for master linked job nets, linked job nets, and job nets at levels below these linked job nets, can be changed. Even if the remarks for a master linked job net, or a job net at a level below the master linked job net, are changed, the changes will not be reflected to the linked job nets that refer to the changed job net. However, if remarks for a master linked job net, or a job net at a level below the master linked job net, are registered or changed, the remarks will be reflected to any new linked job nets that are subsequently registered.
