[2] Precautions during parameter setting
(1) When the "3: External input signal 1 of QD77MS", "4: External input signal 2
of QD77MS", "5: External input signal 3 of QD77MS", or "6: External input
signal 4 of QD77MS" is set in the QD77MS2/QD77MS4, the error "External
input signal selection error" (error code: 936) occurs at turning the PLC
READY signal [Y0] ON, and the READY signal [X0] is not turned ON.
Set "0: External input signal of QD77MS" to use the external input signal of
QD77MS2/QD77MS4.
(2) When the "0: External input signal of QD77MS" is set in the QD77MS16, the
error "External input signal selection error" (error code: 936) occurs at turning
the PLC READY signal [Y0] ON, and the READY signal [X0] is not turned ON.
Set "3: External input signal 1 of QD77MS", "4: External input signal 2 of
QD77MS", "5: External input signal 3 of QD77MS", or "6: External input signal
4 of QD77MS" to use the external input signal of QD77MS16.
[3] Control details
The following table shows the external signal that becomes valid by setting
"[Pr.80] External input signal selection".
