7 Application Instructions API 50-99 From the figure above, we can see that the temperature control after auto-tuning is working fine and we use only approximately 20 minutes for the control. Next, we modify the target temperature from 80°C to 100°C and obtain the result below. From the result above, we can see that when the parameter is 100°C, we can still control the temperature without spending too much time. DVP-PLC APPLICATION MANUAL 7-146
