35 CPU MODULE BUILT-IN ANALOG FUNCTION
35.4 Functions (Analog Output)
Shift function
Function that adds the set input value shift amount to the digital value.
Changes to the input value shift amount will be reflected in the digital operation value in real time, allowing fine adjustments to
be easily performed during system startup.
Corresponding devices
The devices which are used by the shift function are listed below.
Setting methods
Set the desired input value shift amount when performing a shift addition.
Operation
When the added digital value resulting from the shift processing exceeds the range between -32768 and +32767, the value is
fixed to the lower limit (-32768) or the upper limit (32767).
After the value is written for the input value shift amount, the input value shift amount is added to the digital value.
The scaling function and the warning output function are executed for the digital value to which the shift amount has been
added.
Warning output function
Function that checks the digital value set for output against the warning output upper limit and lower limit values configured in
advance for each channel, and outputs a warning when the value is outside the set range.
Corresponding devices
The devices which are used by the warning output function are listed below.
Setting methods
The procedure to use the warning output function is described below.
1. Disable the warning output setting.
