(3) Using the scaling function (for example in the Q68AD-G) to change a resolution
If the module after replacement (for example, the Q68AD-G) supports the scaling function
can be changed using this function.
(Condition)
(a) Resolution of an A series analog I/O module: 1/8000 (Only one channel is used.)
(b) Q series analog I/O module: Q68AD-G
(Example of sequence program to set the function and read the scaling value)
