Execution

On the application program of the PLC, the user sets the command variable to the value 1.

The versiondog server checks the value of the command variable (Trigger URL) at specified intervals of 1 minute. If the variable has the value 1, the job is added to the queue for job execution.

When the job starts, versiondog writes a 1 to the status variable on the controller. As soon as the job has been successfully executed, the status variable receives the value 2. To allow a restart, versiondog sets the value back to 0 on the controller.
