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 3 As shown above, the function of ITEM032 (bumpless processing between
primary/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.
However, control is as follows when the primary loop MV1 must be switched
to the secondary loop PV2 when the secondary loop is set to Manual.
When the secondary loop is set to Manual, turn the primary loop MV tracking
switch ON and use the secondary loop PV2 to switch the primary loop MV1
to this PV2. The following shows an example of this.
