Autotuning the PIDE Instruction
The Logix Designer application PIDE autotuner provides an open-loop autotuner
built into the PIDE instruction. You can autotune from PanelView terminal or
any other operator interface devices, as well as the Logix Designer application. The
PIDE block has an Autotune Tag (type PIDE_AUTOTUNE) that you specify
for those PIDE blocks that you want to autotune.
The PIDE autotuner is installed with the application, but you need an activation
key to enable it. The autotuner is only supported in function block programming;
it is not available in ladder diagram or structured text programming.
Use the Autotune tab to specify and configure the autotune tag for a PIDE block.
