Table 9- 11 Inserting the PID instruction and the technological object
When you insert a PID instruction into your user program,
STEP 7 automatically creates a technology object and an
instance DB for the instruction. The instance DB contains
all of the parameters that are used by the PID instruction.
Each PID instruction must have its own unique instance
DB to operate properly.
After inserting the PID instruction and creating the
technological object and instance DB, you configure the
parameters for the technological object (Page 337).
