When the auto tuning result reflection function is used, the tag types connectable as primary loops are as
follows.
• PID
• 2PID
• 2PIDH
When PID parameters are tracked, the parameter values stored in this tag FB are not restored even though
"Restore" is performed with the PX Developer monitor tool after auto tuning is completed in the primary loop.
Perform the following operations to restore the PID constants to the one before the auto tuning.
• Set the PID parameter tracking flag (PRM_TRK) of this tag FB to "Not executed" (0).
• Set the PID parameter before the auto tuning in the primary loop for the PID parameter of this tag FB.
• Set the PID parameter tracking flag (PRM_TRK) of this tag FB to "Executed" (1).
