RESTR block will never save [ERROR 309]

RESTR block will never save [ERROR 309]

RESTR block Module 1,01,02 Block 1000 will *never* save because S2 is unwired and S3 is wired to constant 0

This RESTR has one or both of S2 and S3 unwired or wired to constant logic 0. This block will never save

A RESTR block will perform the save operation if, and only if, there is a logic 1 on both S2 and S3. If this never happens then when the restore operation is performed, the value restored will likely not be useful.

For best results, logic should be used to set S2 and S3 at times appropriate for a save operation. This might be on a time schedule, or when the value to be saved has changed (or changed enough) to make it useful to save.

This message is likely to show an error in the system configuration. It should be reviewed. The issue raised may be in unused logic or graphics, or have other realities that make it a non-issue.
