7 ANALOG I/O MODULE MIGRATION

7.3 Comparison of Analog I/O Module Functions
Description
A control mode can be selected from the following modes.
• Standard control
• Heating-cooling control (normal mode)
• Heating-cooling control (expanded mode)
• Mix control (normal mode)
• Mix control (expanded mode)
Whether to clear or hold the transistor output status when a
CPU module stop error occurs or when a CPU module is
turned from RUN to STOP can be selected.
The following control methods can be used with the settings
of proportional band (P), integral time (I), and derivative time
(D).
• Two-position control
• P control
• PI control
• PD control
• PID control
The stable status position in the P control or PD control can
be moved manually.
A manipulated value (MV) can be set manually by users
without being automatically calculated by the PID control.
Sets suitable PID constants automatically.
In addition to the PID control, this function selects a suitable
response speed for the set value (SV) change from three
levels to simply achieve the two-degree-of-freedom PID
control.
This function improves dynamic characteristics by selecting a
suitable derivative action for fixed value actions or ramp
actions.
The change rate setting of the set value (SV) per set time unit
when this value is changed. The batch setting or individual
setting can be selected for the temperature rise and drop.
Moving averaging process can be set to a temperature
process value (PV). With this function, the fluctuation of
temperature process values (PV) can be reduced in
electrically noisy environments or in the environments where
temperature process values (PV) fluctuate greatly. The
moving averaging process can be disabled to hasten the
response to the change of temperature process values (PV).
This function can convert temperature process values (PV)
into the set width to import them in the buffer memory.
This function issues an alert when a temperature process
value (PV) or deviation (E) meets the condition set in
advance.
When deviation (E) continues for a long period of time, this
function prevents the PID operation results (manipulated
value (MV)) calculated by integral actions from exceeding the
effective range of the manipulated value (MV).
