Appendix 3 How to Change Resolution After Analog I/O Module is
Replaced
This section describes how to change the resolution of an analog I/O module after the module is
replaced from AnS series to L series.

Appendix 3.1 Resolution

The following table lists a example of the resolutions for the AnS series and L series analog I/O
modules.
Each AnS series analog I/O module has different resolution. Please check the resolution of the
module in this handbook or user
If the resolution differs between AnS series and L series modules, it needs to be matched by a user (by
creating a sequence program or changing user range settings).

*1 Adjust the resolution using the scaling function. (Refer to Appendix 3.2.)
*2 Change the resolution in a sequence program. (Refer to Appendix 3.2.)

Appendix 3.2 Using the scaling function of an analog I/O module

By using the scaling function of the L series analog I/O module, a resolution can be changed.
(1) Example of setting intelligent function module parameters
Parameters can easily be set by using the intelligent function module parameters of GX Works2 without
a program. For details of the setting procedure, refer to the manual for each module.
(Setting conditions)
(a) Resolution of the AnS series module: 1/8000 (Only one channel is used.)
(b) L series module: L60AD4
(Example of scaling setting window)
Point
The scaling value (digital operation value) and digital output value of the analog input module are stored
different buffer memory addresses, therefore, the scaling value of each channel needs to be read from
the buffer memory.
