Explanation
1. This instruction works only with AS series (FWV1.06.00) and ISPSoft V3.06 or later versions.
2. Xno is the starting input number to refresh. Length is the length to refresh. If the X point is the built-in input point of
a CPU, when Xno is X0.3, the value of Length is 3, after executing the REFF instruction, the input filtering time of
X0.3 ~ X0.5 are refreshed.
Since X input point of the extension module is grouping in 8 for a unit, when Xno is X1.9 and the value of Length
is 3, after executing the REFF instruction, the input filtering time of X1.8 ~ X1.15 are refreshed. When Xno is 1.3,
and the value of Length is 3, after executing the REFF instruction, the input filtering time of X1.0 ~ X1.7 are
refreshed. When Xno is X1.3 and the value of Length is 9, the input filtering time of X1.0 ~ X1.15 are refreshed.
3. Xno and Length should be set in the input of PLC input system. If the setting exceeds the range, even if you have
executed REFF instruction, the I/O will NOT be refreshed and error message will NOT be shown.
4. If the X point is the built-in input point of a CPU, the filtering time unit is µs. While if the X point is the input point of
