Issue
This is a short guide to show the correct use of output blocks with forced values in Function Block programs
Environment
SmartStruxure AS using Function Block programs
Cause
There is a design difference between the Vista Menta function block programming and the new version for SmartStruxure.
In the old Menta programs it is possible to connect the output from an output block and connect it to an expression block. The forced value from the output block was passed to an expression block connected downstream of the output block. This is NOT supported in SmartStruxure at the current release Ver 1.3 (April 2013)
If this is done in SmartStruxure then should the output block be forced in any way the forced signal is ignored by the downstream block
Resolution
Follow the guidelines as detailed in the attached document.
