Regarding specifications of the forced ON/OFF function for external input/output
Is there any difference in the forced ON/OFF function of external input/output between iQ-F series and iQ-R series?
Answer
The following points are different for the iQ-F series.
・All output disabled flag (SM8034)
When SM8034 is ON, the all output disabled flag is given priority, so all output terminals are turned OFF regardless of forced ON/OFF registration, and only the forced ON/OFF is reflected on the output device.
・Non-latch memory all clear (SM8031)
If SM8031 is ON, forced ON/OFF will not be reflected.
・Memory hold stop (SM8033)
If SM8033 is ON, forced ON/OFF will not be reflected.
・All output disabled flag (SM8034)
When SM8034 is ON, the all output disabled flag is given priority, so all output terminals are turned OFF regardless of forced ON/OFF registration, and only the forced ON/OFF is reflected on the output device.
