Appendix 3.3 Adding the scaling operation function to sequence program

Adding a scaling operation program to the L series sequence program can change a resolution.
(1) Example of scaling operation sequence program
(Sample program conditions)
(a) Resolution of the AnS series module: 1/4000
(b) Device that stores the present value read from the analog I/O module: D0
