(1) This function backs up PID constants set at the completion of auto tuning
automatically in FeRAM.
When 1 is set and auto tuning is started, data in the following buffer memory
addresses are automatically backed up to FeRAM at the completion of auto
tuning.
Buffer memory address name
Proportional band (P) setting
Integral time (I)
Derivative time (D)
Loop disconnection detection
judgment time
Auto tuning status flag (Xn4, Xn5) turns off at the completion of auto tuning.
Write 0 in this setting when the flag turns off.
(2) Do not change this setting during execution of auto tuning.
(3) While auto tuning is being executed with this function enabled, do not change
the setting value, backup data in FeRAM, or perform default setting registration.
(1) A dead band for alerts is set. For details, refer to Section 3.2.10.
(2) For thermocouple input, the setting range is 0 to 1000 (0.0 to 100.0 ).
For micro voltage, voltage and current input, the setting range is 0 to 1000 (0.00
to 10.00%) for full-scale of the input range.
(1) The sampling count for generating an alert is set.
When the value is set, the system is placed in alert status if the sampling count
remains within the alert range between when the measured value (PV) has fallen
within the alert range and when the sampling count reaches or exceeds the alert
delay count.
For details, refer to Section 3.2.10.
(2) The setting range is 0 to 255 (0 to 255 times).
