Right-click the fieldbus function block and
select Function Block Unassign from the
popup menu.
Unassigns Fieldbus block (FFAI101) from
device (ST101), for this example.
TIP
You must unassign the given fieldbus block from its associated device before you can
delete the device from Project.
ATTENTION
If you unassign a Fieldbus block that has a RCAS_IN or ROUT_IN connection from a
Experion block, be aware that the VCR that was formed when the connection was
made is not removed when the block is unassigned. To remove this VCR, you must
delete the block and then recreate it. The same is true, if you want to delete the
RCAS_IN or ROUT_IN connection and re-wire it to the block's CAS_IN pin.
