Example
∗1: By this function, the value of the secondary loop LSP2 is forcibly written
over the primary loop MV1 when the secondary loop is set to Local.
Note As shown above, the function of ITEM032 (bumpless processing between pri-
mary/secondary loops) of the Basic PID block (Block Model 011) or Advanced
PID block (Block Model 012) can be used to enable switching of primary loop
MV1 to the secondary loop LSP2 when the secondary loop is set to Local.

1: The self node overwrites the actual Local Set Point 2
value with primary side MV1 when the self node is the
local node by setting bumpless output to 1 (ON).
