    15 OPERATIONS DURING CONTROL 15-4 Externally Switching the SV No. When two or more target set values (SV) are used, selection of the execution SV No. can be switched by an external contact. Only DI7 to DI10 can be set. This function can be used only when the optional external I/O control function is installed.

    15 OPERATIONS DURING CONTROL 15-5 Auto Tuning Executing and Stopping Auto Tuning Select execution/stop of PID auto tuning (AT). During execution of auto tuning, the optimum PID constants are calculated according to the limit cycle method, and those values are used to automatically perform control action. During execution of auto tuning, hunting caused by the limit cycle occurs near the SV value.

    15 OPERATIONS DURING CONTROL 15-8 Control Standby (STBY) This function is for setting control output, event output or external output (DO) to a standby state (stop), and standing by for input, etc. to stabilize before starting control. Analog output acts regardless of the execution/standby setting. Control output in the Standby Mode becomes the preset output at standby (initial value 0%), and the STBY LED indicator blinks.

    15 OPERATIONS DURING CONTROL 15-9 Pausing/Resuming Ramp Control (RAMP) "Ramp control" is a function for not suddenly changing SV when it is switched but is a function for ensuring that SV changes according to a fixed ramp (rate-of-change). This function enables this device to be used as a simple programmable controller. Ramp control can be paused, resumed and aborted during execution.
