Precautions for replacement
Since the resolution differs between AnS series
and L series modules, it needs to be matched
using a sequence program, user range settings,
or the scaling function (refer to Appendix 3).
The conversion speed of L60AD4 is faster than
A1S68AD. Therefore, noise which were not
imported to A1S68AD can be imported as analog
signals. In this case, use the averaging
processing function to remove the effect of noise.
Consider of replacing with several L60AD4
modules.
The number of occupied I/O points is changed to
16 points.
Wiring needs to be changed.
Recalculation of internal current consumption
(5VDC) is required.
