FX3S/FX3G/FX3GC/FX3U/FX3UC Series
Programming Manual - Basic & Applied Instruction Edition
13 High-Speed Processing – FNC 50 to FNC 59
13.1 FNC 50 – REF / Refresh
Explanation of function and operation
1. 16-bit operation (REF and REFP)
1) When refreshing outputs (Y)
"n" points are refreshed from the output specified in . ("n" must be a multiple of 8.)
- When this instruction is executed, the output latch memory is refreshed to the output status in the specified
range.
2) When refreshing inputs (X)
"n" points are refreshed from the input specified in . ("n" must be a multiple of 8.)
- If the input information is turned ON approximately 10 ms (response delay time of the input filter) before the
instruction is executed, the input image memory turns ON when the instruction is executed.
- In X000 to X017
*1
, the response delay time of the input filter can be changed.
*1. X000 to X007 in the FX
3G/FX3GC.
