Allows you to select the type of tracking and the
output value when a fault condition occurs.
Supported I/O options for the DO function block are
SP Tracks PV in Man, SP Tracks PV in LO, SP Tracks
Retained Target in Man or LO, Fault State to Value,
Use Fault state on Restart, Target to Man if Fault
State Activated, and Use PV for BKCAL_OUT.
