SmartPAC 2 with WPC 2000 Integration User Manual 1128600
Reporting Downtime and Scrap to SFC H-5
downtime reason is backfilled (see Figure H-3 for a schematic time line), SmartPAC logs one
second to the initial error (e.g., “Sensor 5–End of Stock”), assuring that the fault is
documented, and the remaining time to the new downtime reason (e.g., “Waiting for Coil”).
Downtime reasons can also be “forward filled” in Forced Error Dialog mode.
As in Forced Idle Dialog mode, the Forced Dialog message can be programmed to display a
specified number of minutes after the press stops (see Figure H-3). This Error Dialog Time
setting prevents nuisance faults such as “Counter preset reached” from being reported as
downtime.
Persist Dialog Mode
Periods during which the press is powered down are normally documented as Offline Time
and the period following the next power-up assigned to Idle Time. Periods subsequent to
machine power-ups are documented as Idle Time even when the period immediately
preceding the shutdown has been assigned to an Unplanned Downtime reason. The only
machine states that carry over from the period immediately preceding a shutdown to the
period immediately succeeding a power-up are Changeover Time and Planned Downtime. In
