35.2 List of Functions
The following table lists the functions.
Analog input
Analog output
PID control function
List of functions Description Reference
A/D conversion enable/disable setting function Function to enable or disable A/D conversion per channel.
The conversion process time can be reduced by disabling conversion for unused
channels.

A/D conversion
method
Sampling processing Method of converting each analog input at END processing to generate the
equivalent digital output.
Page 578
Time average Method of averaging the time of A/D conversion values and outputting these average
values as the digital signal.
Count average Method of averaging the count of A/D conversion values and outputting these
average values as the digital signal.
Moving Average Method of averaging the analog input for a specified count measured at every END
process, and outputting these average values as the digital signal.
Over scale detection function Function to detect analog input values that are over an input range. Page 580
Scaling function Function that converts user-defined maximum and minimum digital values in
accordance with a configured scale.
Page 582
Shift function Function that adds a specified amount to the A/D conversion value.
Fine adjustments during system startup can be easily performed.
Page 583
Digital clipping function Function that specifies the maximum A/D conversion value as 4000 and the
minimum value as 0 when voltage is input that exceeds the input range.
Page 581
Maximum value/minimum value hold function Function that holds the minimum and maximum digital operation values. Page 584
Warning output function Function to output warning when digital operation values exceed the specified range. Page 585
Event history function Collects errors that occurred in the CPU module, and stores them as event
information into the CPU module.
Page 586
List of functions Description Reference
D/A conversion enable/disable function Function to enable or disable D/A conversion.
When analog output is not used, the conversion process time can be reduced by
disabling conversion.
Page 588
D/A output enable/disable setting function Specifies whether to output the D/A conversion value or output an offset value
(HOLD setting value).
Page 588
Analog output HOLD/CLEAR function Sets the digital value before D/A conversion to the previous value or clears the value
(0) depending on the operation status of the CPU module (RUN, STOP, and STOP
error).
Page 589
Analog output test when CPU module is in
STOP status function
Outputs a user-defined analog value by setting the output enable/disable flag to
enabled when the CPU module is stopped, and changing the digital value.
Page 590
Scaling function Function that converts user-defined maximum and minimum digital values in
accordance with a configured scale.
Page 591
Shift function Function that adds a specified amount to the digital value.
Fine adjustments during system startup can be easily performed.
Page 592
Warning output function Function to output warning when digital values exceed the specified range. Page 592
Event history function Collects errors that occurred in the CPU module, and stores them as event
information into the CPU module.

List of functions Description Reference
PID control via instruction function Performs PID control by the PID instruction. Page 595
PID control via parameter function Performs PID control (standard PID control, heating-cooling PID control) by using GX
Works3 parameters.
