3-3-2 Precaution
For PC system settings, select the cycle OUT refresh method for output refresh-
ing (DM 6639) as much as possible. If the user needs to select direct OUT re-
fresh method, take the following into consideration.
Word n
Data output
Word n + 1
Data output
0.5 ms
Completion of output
After executing an instruction, it takes approximately 0.5 ms for output comple-
tion. If a new instruction or the END instruction is executed within 0.5 ms, the
completion of the output of the previous instruction may delay.
When turning PC on or off, the output terminal may have voltage momentarily
(i.e., approximately 1 V for a few milliseconds). If this causes a problem, take an
appropriate countermeasure externally.
