The Total Memory and Used Memory totals were incorrect in the Windows simulation after the SCN 4520 - Simulated Battery Backed Ram change.

Record Memory was being included in one of the segments that get added to the Total Mem and Total Used row. That resulted in it being counted more than once. Moving Records into its own segment on Windows and Adjusting how the total memory is calculated in Windows resolved the issue.

Hole Correction must work slightly differently if the XL is placing the holes that it then corrects on vs detecting and correcting on holes than another control system is placing.

A new setup parameter called Hole Correction Mode has been added to allow the operation to configured.

The setup has two settings, Synchronous and Asynchronous.

Select Synchronous if the holes are being placed by the XL using the same encoder as the cutoff.

Select Asynchronous if the holes are placed by another control system using a separate encoder.

When Asynchronous is selected, the controller compares the measured length of the parts (based on hole locations) to the expected length of the parts calculates a Hole Correction factor to adjust the targets that is adds to the queue. This adjustment must occur to prevent the XL targets from drifting out of Hole Tolerance with respect to the holes it is correcting on.

The Hole Correction Diagnostic screen was modified to show the current setting for Hole Correction Mode.

Asynchronous mode requires an Initial Hole in order to initialize the part queue. The controller will shear on this hole to start the process. If there is no hole present when the queue is initialized the controller will halt and display a Missing Initial Correction Hole error. This hole must be located in the material beyond the leading edge of the coil. If a hole is detected prior to the strip making it beyond the sensor an Invalid Initial Correction Hole error will be displayed and the controller will be halted.

The initial hole must be detected before entering the Run Mode. This will require the operator to clear the Queue and then jog the hole through the sensor before placing the controller into run.

Hole Correction was enabled on the following Models:

1. XL202CLF, XL206CLF, XL212CLF
2. XL202HCLF, XL206HCLF, XL212HCLF
3. XL200HCL
4. XL244HCL
5. XL200H
6. XL202H, XL206H, XL212H

This is the first time that Hole Detection and Hole Correction have been available in the same controller. Hole Correction is available when a Hole Detect Controller (Hole Mode Select) is in Standard Mode rather than Count Hole Mode.
