Operation
1. When the instruction input is OFF:
Initializes the PID3 instruction.
Operation mode is set as specified by B+8.
Auto mode SV is set as specified by B+4.
Manual mode MV is set as current MV.
Internal calculation data is initialized.
MV remains unchanged.
2. When the instruction input is ON:
Executes PID calculation every n scan which is specified by B+12. The following operation modes are
available according to the setting of A+5.
Auto mode
This is a normal PID control mode with ASV as set value.
Set value differential limit DSV, manipulation value upper/lower limit MH/ML and differential limit DMV
are effective.
Bump-less changing from auto mode to manual mode is available. (Manual mode manipulation value
MMV is over-written by current MV automatically. MMV
