Purpose
The Fanout (FN) block sends the value it receives to the Next Block and up to four additional blocks. The block listed as a Next Block receives the value immediately. The additional destination blocks receive the value the next time iFIX scans those blocks. If the destination block is in Manual mode, the update is instantaneous.
Features
The Fanout block:
- Is a secondary block.
- Sends values to blocks that are in the same database.
- Requires that the target primary blocks be in Manual mode to receive values.
- Can only send values to a Trend block that is in the Next Block field.
- Does not place blocks on scan by sending its values.
- Does not generate alarms.
- Can be used in a chain with exception-based or time-based processing.
