10-4. Auto tuning Auto tuning (AT) is a function that automatically calculates PID constant. There are four types of auto tunings namely AT1 to AT4 as shown below. ① AT1 ・It is an auto tuning for output 1. ・It can be executed in RUN status (excluding program end status) or in constant value control status. ・Execute auto tuning by using SV when AT1 is set.
10-5. PID control PID is the most generic control algorithm that consists of three operations namely P (Proportion), I (Integration) and D (Differentiation). ① P operation ・It is the basic operation of PID control. It largely affects the responsiveness and the stability. Offset occurs only in proportion operation.

10-9. Transmission signal output It is a function that selects one type from PV (measurement value), SV (measurement value), MV1 (Output value 1), MV2 (Output value 2), MFB (feedback value), SUB (subsidiary output) and outputs using analog signal. Output 2 specifications of transmission signal output depending on the format are also available. For example it is used in applications like, selecting a PV transmission and connecting that analog signal to the recorder and recording the PV of this controller in the recorder.

Term Explanation In the function that has delay in alarm output, initial alarm is switched ON, when the judgment time of alarm ON is continuously equal to the setting value or more. If the judgment time of alarm ON, is less than the setting value, alarm is not switched ON. Alarm delay For example, if setting value of alarm delay is 5, when alarm is activated continuously for 5 seconds or more, initial alarm is switched ON.
