Control Selector Function Block

The Control Selector (CSEL) function block (figure 8‐6) selects one of three control signals to perform override control
to a PID function block. The block supports mode control. The outputs are calculated based on the actual operation
mode, which is determined by parameter values and input value statuses.
There are no standard alarms in this function block. Custom alarms are supported.
Figure 8‐6. Control Selector (CSEL) Function Block
BKCAL_IN is the analog input value and status from a downstream block's BKCAL_OUT output that is used for
backward output tracking for bumpless transfer.
SEL_1 is the first input value to the selector.
SEL_2 is the second input value to the selector.
SEL_3 is the third input value to the selector.
BKCAL_SEL_1 is the selector output value associated with SEL_1 for backward output tracking to an upstream PID
function block.
BKCAL_SEL_2 is the selector output value associated with SEL_2 for backward output tracking to an upstream PID
function block.
BKCAL_SEL_3 is the selector output value associated with SEL_3 for backward output tracking to an upstream PID
function block.
OUT is the output value and status.
