[Functions]

MELSEC-Q

(1)The PFWRT instruction completion can be confirmed using the complete devices ((D)+0) and ((D)+1).

(a)Complete device ((D)+0)

This device is turned ON by the END processing of the scan for which PFWRT instruction is completed, and turned OFF by the next END processing.

(b)Complete state display device ((D)+1)

This device is turned ON and OFF according to the state in which PFWRT instruction is completed.

• When completed normally : Kept unchanged at OFF.

When completed abnormally : This device is turned ON by the END processing of the scan for which PFWRT instruction is completed, and turned OFF by the next END processing. (same ON/OFF

operation as complete device).
