E_CYCLE Test Statistics

Here are some E_CYCLE performance statistics collected on various platforms using JUnit 3. For more details see www.holobloc.com/doc/fb/rt/events/E_CYCLETest.htm.

Dynamic Updating of E_CYCLE period

There has been some discussion within the IEC 61499 Maintenance Team of the appropriate behavior of E_CYCLE blocks when doing programmatic updates of the cycle period (DT input) while the block is running. The events/E_CYCLE documentation on the FBNavigator site explains how this is done in the FBDK, and a new test/E_CYCLE_DEMO system configuration is included in today's FBDK self-update with documentation on the FBNavigator site showing you how to use an E_DELAY block to obtain the correct STOP/START event sequencing for this purpose.
