Resetting Time/Date/Events Specifications

Even if you have defined a time, a date, or an event-based triggering scheme, you can change these settings through links. This lets you redefine the operation of your system without modifying the SQT blocks. It provides you with the ability to change the execution of a batch, the upload of process information, or suspend operation until maintenance is performed on critical operating equipment.

For example, if iFIX ODBC downloads batch recipes that are stored in a relational database, operation can be suspended and rescheduled to a future date through a display link.

The following figure shows a cookie production line that has experienced a mechanical failure. The next recipe download has been rescheduled by changing the trigger time through a display link.

NOTE: When a Text block is used to trigger an event, ODBC SQL can only read the first 40 characters from the block's A_CV field. If you include more than 40 characters in this field, the additional text is ignored.
