Precautions for replacement
ibility
*1
Set "2" at the intelligent
function module switch setting.
*2
On QD62-H02, as the value is
used with 32-bit signed binary
values, change of sequence
program is required.
On QD62-H02, as the external
input specifications differ,
confirm the external devices
specifications.
