| Date: | 5/19/99 |
| Product: | SPEL for Windows 1.x and 2.x (all versions) |
| OS: | Windows 3.1, Windows '95, Windows '98 and Windows NT 4.0 |
| Problem: | Checksum error 87 or time out during project build |
Symptoms
During project build, checksum error 87 occurs or
there is a communication time out.
Causes
The safe guard input is being toggled while files
are being sent to the controller. This causes check sum errors in the
controller's RAM disk. It can also cause communication timeouts.
Remedies
Ensure that the safe guard input state does not
change during project build.
If error 87 previously occurred, you
should format the RAM disk area and then rebuild the project.
